  Description of the Talk

   

  Quantum Computing, having the ability to exponentially enhance the raw computing power, and Artificial Intelligence (AI), having the ability to impart unprecedented intelligence to connected devices through algorithms that learn, are the two key technologies of the 21st century. Although novel devices can significantly advance the field of quantum computing, conventional CMOS based analog and mixed signal circuits can enable quantum computing using classical op amp based circuits. AI algorithms on the other hand are tolerant to errors in computation, thereby enabling approximate and low-precision computing which has resulted in the resurrection of more than half-a-century old analog computing.

  This talk would present various analog computing techniques that could enable AI algorithms or more specifically machine learning (ML) algorithms. The talk could also delve into mixed-sginal computing where it will dive into the details of in-memory computing as well as adoption of novel memory devices, viz., memristors, to enable energy efficient computing. The talk would also present some classical analog hardware for emulating quantum algorithms, like Grover’s search algorithm, for quantum computing systems.

  Description of the Talk

   

  This talk will cover practical challenges for cryogenic CMOS designs for next generation quantum computing. Starting from system level, it will detail the design considerations for a non-multiplexed, semi-autonomous, transmon qubit state controller (QSC) implemented in 14nm CMOS FinFET technology. The QSC includes an augmented general-purpose digital processor that supports waveform generation and phase rotation operations combined with a low power current-mode single sideband upconversion I/Q mixer-based RF arbitrary waveform generator (AWG). Implemented in 14nm CMOS FinFET technology, the QSC generates control signals in its target 4.5GHz to 5.5 GHz frequency range, achieving an SFDR > 50dB for a signal bandwidth of 500MHz. With the controller operating in the 4K stage of a cryostat and connected to a transmon qubit in the cryostat’s millikelvin stage, measured transmon T1 and T2 coherence times were 75.5μs and 73 μs, respectively, in each case comparable to results achieved using conventional room temperature controls. In further tests with transmons, a qubit-limited error rate of 7.76×10-4 per Clifford gate is achieved, again comparable to results achieved using room temperature controls. The QSC’s maximum RF output power is -18 dBm, and power dissipation per qubit under active control is 23mW. An improved, low power design version that achieves half of this power will also be presented.

• 2024 IEEE CASS Seasonal School on “Intelligence in Chips: Memristive Sensing & Bioinspired Computing Systems”
   

  October 16-19, 2024, Online

   

  https://www.intelligenceinchip.com/

   

  Description of the Seasonal School Technical Theme:

   

  We propose to organise the third seasonal school, continuing our highly successful CASS seasonal school in 2021 on “Intelligence in Chip: Tomorrow of IC” and 2022 on “Intelligence in Chips: Integrated Sensors and Memristive Computing”. Our past workshops were hosted by the Kerala chapter. This year, the German chapter proposes to organise this in its push to reinitiate activities in Germany, in partnership with colleagues from Italy and India.
  
  The 2021 school explored the future design of intelligence in IC while the 2022 workshop explored sensing and computing using memristors on a chip. In the third workshop, we will enhance the system element of intelligent sensing on a chip, particularly based on image sensing. A large number of proposed AI circuits aim to work on images and videos produced by CMOS image sensors, while being bioinspired. We aim to showcase the integration of these two circuit design approaches – that of image sensors and bioinspired computing approaches using novel memory elements of Memristors. We have planned a series of very concentrated seminars lasting 3 days on joint design of imaging and intelligence using traditional CMOS circuits jointly with Memristors. In addition to updates on design aspects of these, we will also concentrate on manufacturability of these devices, and we will train CASS student and wider membership on potential fabrication routes for such systems. In addition to training seminars, we also propose to have case studies of designing such systems from leading academic and industrial groups in the field.
