class=\"wp-block-paragraph\">Lorsqu\u2019un rayon lumineux non polaris\u00e9 p\u00e9n\u00e8tre dans un cristal de calcite parfait \u00e0 un angle droit par rapport \u00e0 la surface, il se divise en deux rayons. Le premier traverse le cristal et \u00e9merge de la face oppos\u00e9e en suivant un chemin rectiligne, dans la continuit\u00e9 du rayon incident, comme dans toute exp\u00e9rience de r\u00e9fraction avec un cristal parall\u00e9l\u00e9pip\u00e8de. Mais un autre rayon est form\u00e9 au point d\u2019incidence, qui forme un angle diff\u00e9rent de z\u00e9ro avec le rayon incident. Cela ne se produit pas ordinairement, puisque le trajet d\u2019un rayon incident qui arrive perpendiculairement \u00e0 la surface n\u2019est en g\u00e9n\u00e9ral pas \u201cbris\u00e9\u201d; par cons\u00e9quent, ce second rayon est appel\u00e9 le <strong>rayon r\u00e9fract\u00e9 extraordinaire<\/strong>. \u00c0 son \u00e9mergence du cristal, par le c\u00f4t\u00e9 inverse, ce rayon est \u00e0 nouveau r\u00e9fract\u00e9, poursuivant ensuite un chemin parall\u00e8le \u00e0 celui de l\u2019autre rayon qui s\u2019\u00e9chappe. Dans le cristal, tout comme apr\u00e8s leur passage, ces deux rayons poss\u00e8dent une polarisation lin\u00e9aire. Les rayons ordinaire et extraordinaire ont des directions de polarisation perpendiculaires. Pour le rayon extraordinaire E, cette direction se trouve dans le plan qui contient \u00e9galement les deux rayons, mais elle est orthogonale au rayon lui-m\u00eame. Quant au rayon ordinaire O, sa direction de polarisation est perpendiculaire \u00e0 ce plan. Pour bien diff\u00e9rencier le rayon d\u2019incidence parmi les autres, il a \u00e9t\u00e9 repr\u00e9sent\u00e9 en vert sur la figure 3D suivante, et uniquement sur celle-l\u00e0. Toutefois, il n\u2019y a eu aucun changement de teinte lors du processus physique.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div

class=\"wp-block-paragraph\">Chaque cristal employ\u00e9 par Alice est accompagn\u00e9 de deux lucioles, qui servent de sources lumineuses. Chacune de ces lucioles \u00e9met de la lumi\u00e8re dans un c\u00f4ne dont l\u2019ouverture est assez large sur laquelle est superpos\u00e9 un petit \u00e9cran perfor\u00e9 qui ne laisse passer qu\u2019un fin rayon parall\u00e8le dans la direction perpendiculaire \u00e0 la surface du cristal. Ce faisceau \u00e9troit est masqu\u00e9, sauf lorsque Alice le d\u00e9voile parce qu\u2019elle souhaite l\u2019utiliser comme source de lumi\u00e8re. Les emplacements des lucioles sont soigneusement s\u00e9lectionn\u00e9s. Plus pr\u00e9cis\u00e9ment, les deux points d\u2019incidence sur la face du cristal de leurs rayons lumineux sont choisis avec le but suivant: comme nous avons vu plus haut, chacun des rayons produit, au point de r\u00e9fraction, deux rayons, un ordinaire et un extraordinaire \u2013 les deux points d\u2019incidence sont localis\u00e9s tels que le rayon extraordinaire E1 de la luciole 1 et le rayon ordinaire O2 de la luciole 2 sortent de la face oppos\u00e9e du cristal exactement au m\u00eame endroit. Les deux autres faisceaux r\u00e9fract\u00e9s, le faisceau normal O1 provenant par la luciole 1 et le faisceau extraordinaire E2 provenant de la luciole 2, ne sont pas n\u00e9cessaires pour cette situation particuli\u00e8re. Ils sont repr\u00e9sent\u00e9s sur le sch\u00e9ma suivant par une portion tr\u00e8s courte (absente des illustrations subs\u00e9quentes). On pourrait placer de petits \u00e9crans absorbants au point de sortie de ces rayons pour les \u00e9liminer. Comme les rayons E et O ont des directions de polarisation diff\u00e9rentes, chaque association de deux lucioles et d\u2019un cristal de calcite correspond, pour Alice, \u00e0 une source de lumi\u00e8re polaris\u00e9e qu\u2019elle peut choisir selon sa convenance (correspondant \u00e0 la luciole dont elle enl\u00e8ve le masque).&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La figure

Les cristaux sont dispos\u00e9s de mani\u00e8re \u00e0 ce que leurs rayons \u00e9mergents convergent vers un m\u00eame point, formant un angle droit. \u00c0 l\u2019endroit o\u00f9 les deux rayons se rencontrent, un miroir semi-argent\u00e9 est install\u00e9, perpendiculairement au plan form\u00e9 par les deux rayons, et de mani\u00e8re \u00e0 former un angle de 45&nbsp;degr\u00e9s avec chacun d\u2019entre eux. Parce que le miroir est semi-argent\u00e9, un photon qui arrive au miroir en suivant l\u2019un ou l\u2019autre des deux rayons a 50&nbsp;% de chances d\u2019\u00eatre transmis sans changement de direction, et 50&nbsp;% de chances d\u2019\u00eatre r\u00e9fl\u00e9chi. L&rsquo;illustration en trois dimensions montre comment le rayon r\u00e9fl\u00e9chi d\u2019un cristal correspond au rayon continu de l\u2019autre. (Au-del\u00e0 du miroir, il existe aussi un autre trajet possible pour la lumi\u00e8re, o\u00f9 le rayon du premier cristal continuerait sans r\u00e9flexion. Il co\u00efnciderait alors avec le rayon r\u00e9fl\u00e9chi provenant du second cristal. Cette alternative n\u2019est pas consid\u00e9r\u00e9e ici \u2013 un autre petit \u00e9cran pourrait bloquer ces photons-l\u00e0.)<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\"

deux parties de l\u2019installation d\u2019Alice, nous les appelons \u00ab\u2009Droit\u2009\u00bb et \u00ab\u2009Oblique\u2009\u00bb. Le c\u00f4t\u00e9 Droit \u00e9met des photons polaris\u00e9s lin\u00e9airement, dont la direction est soit dans le plan d\u00e9fini par les deux rayons arrivant au miroir semi-argent\u00e9, soit perpendiculaire \u00e0 ce plan. Nous appelons ces directions de polarisation \u00ab\u2009horizontales\u2009\u00bb (ou \u00ab h\u2009\u00bb) ou \u00ab\u2009verticales\u2009\u00bb (ou \u00ab\u2009v\u2009\u00bb), selon le cas. Les photons du c\u00f4t\u00e9 Oblique ont des directions de polarisation que nous appellerons \u00ab\u2009gauche\u2009\u00bb (g) ou \u00ab\u2009droite\u2009\u00bb (d). Au-del\u00e0 du miroir semi-argent\u00e9 d\u2019Alice, le faisceau \u00e9manant de son installation se compose de quatre types de photons: Dh, Dv, Og et Od.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Envoi de la s\u00e9quence de photons par Alice<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Dans le cadre du protocole BB84, Alice transmet une s\u00e9rie de photons \u00e0 Bernard par l\u2019interm\u00e9diaire du canal ouvert, un \u00e0 la fois \u00e0 des intervalles de temps pr\u00e9d\u00e9termin\u00e9s. Alice \u00e9met des photons lin\u00e9airement polaris\u00e9s des quatre types distincts,&nbsp; s\u00e9lectionnant al\u00e9atoirement le c\u00f4t\u00e9 et la direction de polarisation de chaque photon qu\u2019elle \u00e9met. Elle note les choix qu\u2019elle fait. Le miroir semi-argent\u00e9 d\u2019Alice achemine chaque photon vers Bernard avec une pr\u00e9cision de 50% (les 50% restants empruntent un chemin diff\u00e9rent et ne servent donc \u00e0 rien). Par cons\u00e9quent, un photon atteindra Bernard environ la moiti\u00e9 du temps aux instants pr\u00e9vus par l\u2019entente pr\u00e9alable entre Alice et Bernard.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">L\u2019installation de Bernard<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Bernard, quant \u00e0 lui, dispose d\u2019un assemblage similaire \u00e0 celui d\u2019Alice, comme le montre la figure ci-dessous. Lorsque la lumi\u00e8re traverse l\u2019assemblage, elle heurte d\u2019abord un miroir semi-argent\u00e9. Chaque photon est alors soit transmis directement sans r\u00e9flexion, soit r\u00e9fl\u00e9chi \u00e0 90&nbsp;degr\u00e9s par rapport \u00e0 son angle d\u2019incidence initial, selon un sch\u00e9ma

miroir semi-argent\u00e9 de Bernard renvoie chaque photon qui le frappe soit vers le cristal identique \u00e0 celui utilis\u00e9 par Alice pour produire ce photon (c\u2019est-\u00e0-dire le cristal Correct) ou vers l\u2019autre cristal (le cristal Incorrect), avec une probabilit\u00e9 de 50% pour chaque option. Si le photon arrive \u00e0 son cristal Correct, sa direction de polarisation est d\u00e9j\u00e0 align\u00e9e avec les directions sp\u00e9ciales pour ce cristal-l\u00e0; il suivra dans le cristal le chemin d\u00e9termin\u00e9 par sa polarisation, et quittera le cristal par le point de sortie correspondant \u00e0 cette polarisation. Bernard a plac\u00e9 une grenouille d\u2019une esp\u00e8ce rare \u00e0 chacun des quatre points de sortie possibles des deux cristaux. Sa r\u00e9tine est capable de d\u00e9tecter des photons individuels. Ces grenouilles ont \u00e9t\u00e9 dress\u00e9es \u00e0 sauter lorsqu\u2019elles d\u00e9tectent un photon. Quand un photon atteint son cristal Correct, Bernard peut en conclure, \u00e0 partir des r\u00e9actions de ses grenouilles, si Alice a \u00e9mis un photon de polarisation v ou h (si D est le cristal Correct) ou g ou d (si O est le cristal Correct). Lorsqu\u2019un photon atteint un cristal Incorrect, sa polarisation forme un angle de 45&nbsp;degr\u00e9s par rapport \u00e0 chacune des directions sp\u00e9cifiques de ce cristal. Par cons\u00e9quent, le cristal redirige la polarisation du photon vers l\u2019une de ses deux directions sp\u00e9cifiques, avec une probabilit\u00e9 de 50% pour chacune. Dans ce cas, Bernard ne peut tirer aucune information utile du comportement des grenouilles.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Bernard et Alice apprennent la cl\u00e9 secr\u00e8te<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Il est clair que Bernard ignore si le photon qui arrive chez lui a abouti \u00e0 son cristal Correct ou Incorrect. Cependant, il est capable de communiquer avec Alice. Apr\u00e8s chaque instant pr\u00e9d\u00e9termin\u00e9 avec elle, o\u00f9 elle a envoy\u00e9 un photon, il lui fait savoir si le photon est arriv\u00e9 chez lui ou non (seulement la moiti\u00e9 arrive \u00e0 bon port, comme nous l\u2019avons vu plus t\u00f4t). Dans le cas o\u00f9 le photon est arriv\u00e9, il indique de quel c\u00f4t\u00e9 il est sorti, D ou O. Pour chaque photon qui arrive chez lui, Alice indique \u00e0 Bernard si la d\u00e9termination de ce dernier correspond au c\u00f4t\u00e9 qu\u2019elle a utilis\u00e9. Apr\u00e8s plusieurs \u00e9changes d\u2019informations, Bernard et Alice sont maintenant en mesure de d\u00e9terminer quels photons ont parcouru le chemin d\u2019Alice \u00e0 Bernard sans que leur orientation de polarisation ait \u00e9t\u00e9 modifi\u00e9e. Bernard est d\u00e9sormais capable d\u2019identifier pr\u00e9cis\u00e9ment la direction de la polarisation choisie par Alice pour ces photons.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En attribuant une valeur 0 \u00e0 l\u2019une des deux orientations de polarisation possibles pour chaque photon inchang\u00e9, et une valeur 1 \u00e0 l\u2019autre, Alice et Bernard ont ainsi convenu d\u2019une suite de bits totalement al\u00e9atoire, sans jamais avoir exprim\u00e9 explicitement cette information lors de leurs conversations sur le canal ouvert.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Voici une illustration de l\u2019installation compl\u00e8te des deux c\u00f4t\u00e9s: Alice et Bernard. Dans cette situation, chaque cristal a \u00e9t\u00e9 \u00e9tiquet\u00e9 avec des lettres \u00ab\u2009A\u2009\u00bb ou \u00ab\u2009B\u2009\u00bb afin de le diff\u00e9rencier sur tous ses c\u00f4t\u00e9s, m\u00eame apr\u00e8s une rotation en trois dimensions. Cette figure sert aussi de mod\u00e8le pour le dessin de la petite courtepointe. Les d\u00e9tails sont mis en \u00e9vidence par la diminution consid\u00e9rable de la distance entre les deux miroirs semi-argent\u00e9s (et donc de la longueur du canal ouvert) ; cette distance est en r\u00e9alit\u00e9 beaucoup plus grande.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns alignfull

si une tierce personne, habituellement d\u00e9sign\u00e9e par \u00ab\u2009\u00c8ve\u2009\u00bb, \u00e9coute discr\u00e8tement la conversation sur le canal ouvert, dans le but de capter (sans que les autres s\u2019en aper\u00e7oivent) la cl\u00e9 secr\u00e8te qu\u2019Alice et Bernard ont d\u00e9cid\u00e9 d\u2019utiliser\u2009? M\u00eame si Eve conna\u00eet parfaitement les installations d\u2019Alice et de Bernard, il est impossible pour elle d\u2019observer les photons qui traversent sans interf\u00e9rer avec eux. Pour mesurer la polarisation de ces photons au moment de leur passage, Eve devrait les faire passer par un appareil de mesure semblable aux cristaux de calcite utilis\u00e9s par Alice et Bernard. Comme Eve ignore, au moment o\u00f9 le photon traverse l\u2019appareil, quelle direction a choisie Alice, elle ne peut pas faire mieux, en moyenne, que de deviner. Elle a une chance sur deux de deviner juste, ce qui entra\u00eenerait une lecture correcte de la polarisation du photon. Ce dernier poursuivrait alors son chemin vers Bernard, qui resterait dans l\u2019ignorance de la supercherie. Toutefois, si elle se trompe, l\u2019essai d\u2019Eve pour interpr\u00e9ter la polarisation du photon r\u00e9oriente cette polarisation vers l\u2019une des directions sp\u00e9ciales du cristal Incorrect pour ce photon. Le photon, avec sa polarisation alt\u00e9r\u00e9e, a une chance sur deux d\u2019\u00eatre renvoy\u00e9 par le miroir semi-argent\u00e9 de Bernard dans la direction de son cristal Correct; en raison du changement de polarisation op\u00e9r\u00e9 par Eve, la polarisation du photon ne correspond plus \u00e0 ce cristal. Par cons\u00e9quent, le cristal subit une nouvelle rotation de polarisation qui, en moyenne, ne correspond \u00e0 la bonne (c\u2019est-\u00e0-dire celle qu\u2019Alice lui avait initialement donn\u00e9e) que dans la moiti\u00e9 des cas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ceci implique qu\u2019Alice et Bernard peuvent d\u00e9tecter la pr\u00e9sence d\u2019Eve en sacrifiant une partie de la s\u00e9quence de bits d\u00e9termin\u00e9e par les polarisations de photons arriv\u00e9s au cristal Correct de Bernard. Si une comparaison des bits r\u00e9v\u00e8le qu\u2019ils ne sont corrects que dans 75% des cas, cela pourrait indiquer qu\u2019une tierce personne perturbe le chemin des photons. Pour \u00eatre certain qu\u2019il n\u2019y a pas d\u2019\u00e9couteurs ind\u00e9sirables, il faut une proportion beaucoup plus grande de bons bits. Une fois cette v\u00e9rification effectu\u00e9e, ils peuvent utiliser les autres bits (non sacrifi\u00e9s) comme cl\u00e9 de cryptage pour prot\u00e9ger le secret de leurs communications futures.<\/p>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"761\" height=\"451\" src=\"https:\/\/i0.wp.com\/mathemalchemy.org\/wp-content\/uploads\/2023\/11\/Charle_Bennett_frogs.gif?resize=761%2C451&#038;ssl=1\" alt=\"\" class=\"wp-image-11395\"\/><\/figure>\n\n\n\n<p class=\"has-text-align-center has-small-font-size wp-block-paragraph\">Sketch par Charles Bennett.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Admirez l\u2019assemblage complet de la petite courtepointe cryptographique.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"877\" height=\"750\" src=\"https:\/\/i0.wp.com\/mathemalchemy.org\/wp-content\/uploads\/2023\/01\/quantum-cryptography-charles-bennet-gilles-brassard-mathemalchemy-math-art-installation.jpg?resize=877%2C750&#038;ssl=1\" alt=\"\" class=\"wp-image-8754\" srcset=\"https:\/\/i0.wp.com\/mathemalchemy.org\/wp-content\/uploads\/2023\/01\/quantum-cryptography-charles-bennet-gilles-brassard-mathemalchemy-math-art-installation.jpg?w=877&amp;ssl=1 877w, https:\/\/i0.wp.com\/mathemalchemy.org\/wp-content\/uploads\/2023\/01\/quantum-cryptography-charles-bennet-gilles-brassard-mathemalchemy-math-art-installation.jpg?resize=300%2C257&amp;ssl=1 300w, https:\/\/i0.wp.com\/mathemalchemy.org\/wp-content\/uploads\/2023\/01\/quantum-cryptography-charles-bennet-gilles-brassard-mathemalchemy-math-art-installation.jpg?resize=768%2C657&amp;ssl=1 768w\" sizes=\"auto, (max-width: 877px) 100vw, 877px\" \/><\/figure>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Surtout, n\u2019allez pas dans votre jardin pour capturer des grenouilles ou des lucioles afin de cr\u00e9er votre propre version du protocole BB84 !
