Title:
Cryogenic Electronics for Quantum-Classical Applications
Abstract
The core of a quantum computer or a quantum sensor is generally an array of qubits or quantum detectors and classical electronics for its control; it operates on the qubits/detectors with nanosecond latency and a very low noise. Classical electronics is generally operating at room temperature, however recently, we have proposed that it moves closer to the qubits/detectors and operates at cryogenic temperatures to improve compactness and reliability. This has introduced new constraints to the electronics, especially in terms of noise and power dissipation, due to the extremely weak signals generated by quantum devices that require highly sensitive circuits and systems, along with very precise timing capability. We advocate the use of CMOS technologies to achieve these goals, whereas the circuits will be operated at 2-10K. We believe that these, collectively known as cryo-CMOS circuits, will make future qubit arrays scalable, enabling a faster growth in qubit count. Quantum sensing based on superconducting materials, will become more reliable and robust to the conditions of operation. In the talk, the challenges of designing and operating complex circuits and systems at deep-cryogenic temperatures will be outlined, along with preliminary results achieved in the control of quantum devices by ad hoc integrated circuits that were optimized to operate at low power in these conditions. The talk will conclude with a perspective on the field and its trends.
Title:
Quantum imaging and sensing
Abstract
Detecting single photons may enable one to achieve capabilities beyond classical imaging and sensing, for example, better signal-to-noise and signal-to-background ratio, super-resolution, mid-IR and RF sensing, or information hiding in plain sight. An important ingredient in these modalities is technology for single-photon detection, time stamping, and algorithms taking quantum mechanics into account. Solid state single-photon detection may be based on silicon and III-V materials, to sense a large electromagnetic spectrum from near UV to near IR through visible wavelengths. In this talk, we review a wide variety of detectors and how they were extended to multi-pixel cameras to achieve quantum imaging and sensing, with a focus on standard technologies, such as CMOS. The suitability of CMOS single-photon image sensors for quantum imaging and sensing is demonstrated through concrete examples.
