Zhenyu Cai

Dr Zhenyu Cai 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. In addition to leading a £2.2 million EPSRC Fellowship ( £1.7 million funding with £500k industrial support), he 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, contributing to UK-wide efforts in building robust, scalable quantum technologies.

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 mitigation strategies such as multi-exponential error extrapolation, and resource-efficient methods for quantum error mitigation. He has also explored quantum variational simulations and the application of artificial intelligence in quantum computing. His contributions aim to enhance the reliability and performance of quantum technologies in the Noisy Intermediate-Scale Quantum (NISQ) era.
