Variational circuit compiler for quantum error correction
Xiaosi Xu, Simon C. Benjamin, Xiao Yuan
Quantum error correction is vital for implementing universal quantum computing. A key component is the encoding circuit that maps a product state of physical qubits into the encode…
Variational algorithms for linear algebra
Xiaosi Xu, Jinzhao Sun, Suguru Endo +3
Quantum algorithms have been developed for efficiently solving linear algebra tasks. However, they generally require deep circuits and hence universal fault-tolerant quantum comput…
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…
Demonstration of Adiabatic Variational Quantum Computing with a Superconducting Quantum Coprocessor
Ming-Cheng Chen, Ming Gong, Xiao-Si Xu +15
Adiabatic quantum computing enables the preparation of many-body ground states. This is key for applications in chemistry, materials science, and beyond. Realisation poses major ex…
