DESCRIPTION:Speakers: Oleg Mukhanov (SeeQC)\nTraditionally\, the control a
 nd measurement of superconducting quantum devices including arrays of qubi
 ts are done using room-temperature classical electronics connected to cryo
 genic environment via high fidelity cables. This poses daunting technical 
 challenges to quantum system scaling as the heat load\, latency\, noise as
 sociated with bringing signals in and out of the cryostat rise dramaticall
 y with number of quantum devices. By integrating the control and readout e
 lectronics into the cryostat in proximity to quantum devices\, these probl
 ems can be drastically reduced to enable large-scale quantum arrays. This 
 can finally lead to quantum processing systems that can outperform the bes
 t available classical supercomputers.  Superconducting Single Flux Quantum
  (SFQ) digital logic can be a basis for the implementation of a proximal c
 lassical co-processor for low-overhead qubit control and measurement. SFQ 
 digital circuits also can perform in situ classical processing of the resu
 lts of quantum measurement to enable fast error tracking and feedback to s
 tabilize the quantum array. Furthermore\, hybrid quantum-classical systems
  integrating together the quantum and classical processing hardware units 
 can match to various application algorithm architectures which typically c
 ombine quantum and classical algorithmic modules.  Latest results in the S
 FQ-based digital control of superconducting qubits will be presented. The 
 implementation of a scalable quantum-classical 3D integrated system extend
 ing across multiple temperature stages will be discussed.\n\nhttps://indic
