Biography
Dr Zhenyu Cai is a Visiting Fellow in the Department of Engineering Science at the University of Oxford and an Assistant Professor in the Department of Computing at Imperial College London, where he leads the Quantum Error Control research group. He holds an EPSRC Quantum Technologies Fellowship and is also a Senior Quantum Theorist at Quantum Motion.
Before joining Imperial, he held an EPSRC fellowship in Engineering Science at Oxford and was a Junior Research Fellow in Physics at St John’s College, Oxford. He completed his DPhil in Quantum Technologies at the University of Oxford and his BA and MSci in Natural Sciences (Physics) at Trinity College, Cambridge.
Research Interests
Dr Cai develops methods and architectures for reliable quantum computation. His research spans three connected areas:
Quantum error mitigation and correction: developing error-suppression methods and investigating how mitigation and correction can be combined within the same computation.
Practical quantum architectures: designing architectures around hardware constraints, including qubit connectivity, movement, control and leakage, with particular experience in silicon spin-qubit systems.
Quantum algorithms and resource estimation: connecting algorithm design and circuit compilation with error control and physical implementation, accounting for qubit requirements, runtime, repeated measurements and classical processing.
