Cai Zhenyu

Dr Cai Zhenyu is an EPSRC Quantum Technologies Fellow and Principal Investigator in Engineering Science at the University of Oxford. His research focuses on quantum error correction, error mitigation, and their hardware-adapted implementation for different applications, aiming to enable resource-efficient, noise-robust pathways to scalable quantum computing. He previously held a Junior Research Fellowship at St John’s College (2020–2024) and completed his undergraduate studies in Cambridge and DPhil in Oxford. He leads a £2.2 million EPSRC Fellowship and is an investigator on several other grants totalling over £1.3 million. He maintains active collaboration with industrial partners and is the lead inventor on four patents. Dr Cai serves on the organising committee of the £3 million RoaRQ Programme and the SEEQA conference.

Zhenyu Cai is an EPSRC Research Fellow at the University of Oxford, specializing in quantum computation, quantum error correction, and quantum error mitigation. His research focuses on developing practical techniques to address noise in quantum systems, particularly for near-term quantum devices. Cai's work includes hybrid quantum-classical algorithms, error extrapolation methods, and symmetry expansion for error mitigation. He has also explored quantum variational simulations, resource-efficient purification-based techniques, and the design of quantum architectures resilient against leakage errors. His contributions span both theoretical and applied aspects of quantum error mitigation, with an emphasis on improving the reliability and performance of quantum computing systems.
