A termes, pour les ordinateurs quantiques, des milliers, voire des millions de qubits seront n\u00e9cessaires. Or, ceux-ci doivent fonctionner \u00e0 des temp\u00e9ratures autour de -270 \u00b0C (4\u00b0K). Le principal obstacle \u00e0 ce niveau de complexit\u00e9 est ll\u00e9 au volume de contr\u00f4le, qui est directement proportionnel au nombre de qubits dans le syst\u00e8me. Ce probl\u00e8me ne peut donc \u00eatre r\u00e9solu qu’en implantant l’\u00e9lectronique de commande dans le cryostat. Cependant, la puissance g\u00e9n\u00e9r\u00e9e par cette \u00e9lectronique dans le cryostat \u00e9l\u00e8ve sa temp\u00e9rature et compromet le fonctionnement de l’ordinateur. C’est l\u00e0 que SureCore voit une opportunit\u00e9 pour sa m\u00e9moire IP CMOS SRAM ultra basse consommation, puis pour la logique de contr\u00f4le. Un seuil plus bas signifie beaucoup moins de dissipation de puissance \u00e0 g\u00e9rer et donc moins de pertes.<\/p>\n

SureCore, bas\u00e9e \u00e0 Sheffield, vise \u00e0 fournir une IP qui permettra la conception de puces de contr\u00f4le \u00ab Cryo-CMOS \u00bb pouvant \u00eatre colocalis\u00e9es avec les qubits dans le cryostat afin d’aider \u00e0 r\u00e9soudre le probl\u00e8me actuel du volume de c\u00e2blage pour connecter les qubits avec leur \u00e9lectronique de commande associ\u00e9e fonctionnant g\u00e9n\u00e9ralement \u00e0 temp\u00e9rature ambiante \u00e0 l’ext\u00e9rieur du cryostat.<\/p>\n

Cependant, cela n\u00e9cessitera de nouvelles biblioth\u00e8ques complexes caract\u00e9ris\u00e9es pour un fonctionnement en 4\u00b0K.<\/p>\n

Selon Paul Wells, PDG de SureCore.\u00ab Nous sommes particuli\u00e8rement bien plac\u00e9s pour r\u00e9soudre deux des principaux d\u00e9fis du d\u00e9veloppement de Cryo-CMOS. Actuellement, la plage de temp\u00e9rature de fonctionnement industrielle standard pour la plupart des technologies de processus CMOS commerciales est de -40\u00b0C \u00e0 125\u00b0C et cela se refl\u00e8te dans les types de transistor SPICE fournis par les fondeurs de silicium. En travaillant en \u00e9troite collaboration avec des partenaires industriels et des fonderies, nous pr\u00e9voyons de concevoir et de caract\u00e9riser une propri\u00e9t\u00e9 intellectuelle sur silicium capable de fonctionner jusqu’\u00e0 4\u00b0K. Le deuxi\u00e8me d\u00e9fi est de s’assurer que l’\u00e9lectronique de commande dissipe le moins possible de chaleur afin de minimis la charge de refroidissement sur le cryostat. Il est donc essentiel que des techniques de conception \u00e0 faible consommation soient d\u00e9ploy\u00e9es.\u00bb Et  Paul Wells de poursuivre:\u00ab  Nous sommes experts dans la r\u00e9duction de la consommation \u00e9lectrique des CMOS, nos m\u00e9thodes de conception ont d\u00e9j\u00e0 montr\u00e9 jusqu’\u00e0 50 % de r\u00e9duction de puissance dynamique dans les m\u00e9moires IP embarqu\u00e9es. En d\u00e9ployant ces techniques dans la conception de Cryo-CMOS, nous visons \u00e0 minimiser l’exc\u00e8s de chaleur g\u00e9n\u00e9r\u00e9, facilitant ainsi les d\u00e9fis d’\u00e9volutivit\u00e9 pour les grands ordinateurs quantiques \u00bb<\/p>\n

SureCore personnalisera l’adresse IP de sa m\u00e9moire int\u00e9gr\u00e9e appel\u00e9e CryoMem. Celle-ci sera adapt\u00e9e \u00e0 la logique de contr\u00f4le avec une gamme d’IP adapt\u00e9e au d\u00e9veloppement d’une \u00e9lectronique de contr\u00f4le compl\u00e8te.<\/p>\n

\u00ab Cette nouvelle biblioth\u00e8que IP permettra d’acc\u00e9l\u00e9rer le d\u00e9veloppement d’ASIC de contr\u00f4le cryog\u00e9nique rentables pour les entreprises d’informatique quantique qui vont se lancer sur march\u00e9 prometteur pour fournir des solutions de calcul quantique comp\u00e9titives \u00bb, a d\u00e9clar\u00e9 Paul Wells.<\/p>\n
