(38:20 + Q&A) Dr. Imran Bashir, Equal1 -- Presentation from 2023 Workshop on Quantum Computing: Devices, Cryogenic Electronics and Packaging (QC-DCEP) ...  Tutorial: For electrical engineers who are not fully versed in physics and quantum mechanics.
Summary: Silicon based Qubits have been proposed as an alternative to Josephson junction structures when it comes to scaling the quantum processor from hundreds to a thousand Qubits. The control electronics in such system needs to generate a unique RF control and DC bias per Qubit without exceeding the thermal budget of the cryocooler. This Talk describes a monolithic integration of the semiconductor quantum core and its associated classic control circuitry manufactured in the 22FDX fully depleted silicon-on-insulator (FD-SOI) technology from GlobalFoundries. The quantum control signal is synthesized from a single RF reference clock that drives the pulse generator for timing control and the 8bit capacitive DAC for amplitude control. The on-chip cryogenic memory stores unique patterns to generate various quantum gate behaviors. The readout circuits use a sampled architecture designed to reduce the common-mode and flicker noise in the front-end. In addition, a fully integrated bias generation system using a single input reference is proposed for a moderately complex 2D quantum structure. The combined area of the entire control circuitry is 0.042mm² while the total power consumption with a reference clock 2.5GHz is 10.7mW at 3.5K.
Imran Bashir received the BSEE degree from the University of Texas at Arlington in 2001 and the MSEE and Ph.D. degrees from the University of Texas at Dallas in 2008 and 2014. He joined Texas Instruments in 2002 and was elected to Group Member of the Technical Staff in 2006. He played a key role in the productization of GSM/EDGE SoCs based on the Digital RF Processor DRPTM technology. In 2009, he joined NVidia Inc. and worked on 2G/3G/4G multi-mode cellular radios. In 2014, he worked as a Mixed-Signal IC Designer with a start-up called Senseeker Engineering Inc. where he designed read-out circuits for IR image sensors. In 2016, he joined Cypress Semiconductor Corp. as an RF/Analog IC design engineer working on connectivity ICs. In August 2019, Imran joined Equal1 Labs Inc. as VP of Analog Engineering and is working on highly integrated and scalable Quantum Processors. Imran has multiple patents and journal papers in the field of Digital Polar Transmitters, Self-Calibration, Interference Mitigation, and Injection Locked Oscillators. In addition to his day-time job, Imran has volunteered as an officer for the IEEE-SSCS, IEEE-CASS, and IEEE-EDS Santa Clara Valley Chapters. He is a member of Tau Beta Pi and Eta Kappa Nu.
