Resource-efficient Purification-based Quantum Error Mitigation
Zhenyu Cai
To achieve the practical applications of near-term noisy quantum devices, low-cost ways to mitigate the noise damages in the devices are essential. In many applications, the noisel…
Quantum Error Mitigation using Symmetry Expansion
Zhenyu Cai
Even with the recent rapid developments in quantum hardware, noise remains the biggest challenge for the practical applications of any near-term quantum devices. Full quantum error…
Hybrid quantum-classical algorithms and quantum error mitigation
Suguru Endo, Zhenyu Cai, Simon C. Benjamin +1
Quantum computers can exploit a Hilbert space whose dimension increases exponentially with the number of qubits. In experiment, quantum supremacy has recently been achieved by the…
Resource Estimation for Quantum Variational Simulations of the Hubbard Model
Zhenyu Cai
As the advances in quantum hardware bring us into the noisy intermediate-scale quantum (NISQ) era, one possible task we can perform without quantum error correction using NISQ mach…
Mitigating Coherent Noise Using Pauli Conjugation
Zhenyu Cai, Xiaosi Xu, Simon C. Benjamin
Coherent noise can be much more damaging than incoherent (probabilistic) noise in the context of quantum error correction. One solution is to use twirling to turn coherent noise in…
A Silicon Surface Code Architecture Resilient Against Leakage Errors
Zhenyu Cai, Michael A. Fogarty, Simon Schaal +3
Spin qubits in silicon quantum dots are one of the most promising building blocks for large scale quantum computers thanks to their high qubit density and compatibility with the ex…
