Starting fr om the system level\, it will detail design considerations for non-multipl exed\, semi-autonomous transmon qubit state controllers implemented in 14 nm CMOS FinFET technology. The controller includes an augmented general-pu rpose digital processor supporting waveform generation and phase rotation\ , combined with a low-power current-mode single-sideband conversion I/Q mi xer-based RF arbitrary waveform generator. The QSC generates control signa ls in the 4.5 to 5.5 GHz range with SFDR greater than 50 dB for 500 MHz ba ndwidth. With the controller operating at the 4 K stage of a cryostat and connected to a transmon qubit in the millikelvin stage\, measured T1 and T 2 coherence times were 75.5 us and 73 us\, respectively. Further tests ach ieved a qubit-limited error rate of 7.76 x 10^-4 per Clifford gate\, compa rable to conventional room-temperature controls. The talk will also presen t an improved low-power design version and clocking solutions for large ar rays.\n\nSpeaker(s): \, Dr. Sudipto Chakraborty\n\nAgenda: \n[]\n\nRoom: 2 529\, Bldg: DWE\, Univerisity of Waterloo\, Waterloo\, Ontario\, Canada\, N2L 3G1\, Virtual: https://events.vtools.ieee.org/m/576513 LOCATION:Room: 2529\, Bldg: DWE\, Univerisity of Waterloo\, Waterloo\, Onta rio\, Canada\, N2L 3G1\, Virtual: https://events.vtools.ieee.org/m/576513 ORGANIZER:mabuyaghi@gmail.com SEQUENCE:14 SUMMARY:Challenges and Opportunities for Development of Ultra-Low Power Sca led Quantum Computing Systems URL;VALUE=URI:https://events.vtools.ieee.org/m/576513 X-ALT-DESC:Description: <br /><p>This talk will cover practical challenges for the development of integrated system designs for next-generation quant um computing\, combining integrated circuits\, systems\, and microwave eng ineering.
