Researchers at \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne (EPFL) and the Hitachi Cambridge Laboratory have recently designed an integrated circuit (IC) that integrates silicon quantum dots with conventional readout electronics. This chip, introduced in a paper published in Nature Electronics<\/i>, is based on a 40-nm cryogenic complementary metal-oxide semiconductor (CMOS) technology that is readily and commercially available.<\/p>\n

\u201cOur recent paper builds on the expertise of the two groups involved,\u201d Andrea Ruffino, one of the researchers at EPFL who carried out the study, told TechXplore. \u201cThe goal of our group was to build cryogenic (Bi)CMOS integrated circuits<\/a> for readout and control of quantum computers, to be co-packaged or co-integrated in the final stage with silicon quantum processors. On the other hand, the team at the Hitachi Cambridge Laboratory have been studying silicon quantum devices<\/a> for many years.\u201d<\/p>\n

Ruffino and his colleagues at EPFL joined forces with the team at the Hitachi Cambridge Laboratory with the common goal of uniting classical circuits and quantum devices on a single chip<\/a>. Their paper builds on some of their previous efforts, including the proposal of cryogenic CMOS ICs for quantum computing<\/a>, as well as the realization of fast-sensing<\/a> and time-multiplexed sensing<\/a> of silicon quantum devices.<\/p>\n","protected":false},"excerpt":{"rendered":"
