Quantum machine learning with indefinite causal order
Nannan Ma, P. Z. Zhao, Jiangbin Gong
In a conventional circuit for quantum machine learning, the quantum gates used to encode the input parameters and the variational parameters are constructed with a fixed order. The…
Mitigation of systematic amplitude error in nonadiabatic holonomic operations
P. Z. Zhao, Jiangbin Gong
Nonadiabatic holonomic operations are based on nonadiabatic non-Abelian geometric phases, hence possessing the inherent geometric features for robustness against control errors. Ho…
Average value estimation in nonadiabatic holonomic quantum computation
Guo-Fu Xu, P. Z. Zhao
Nonadiabatic holonomic quantum computation has been attracting continuous attention since it was proposed. Until now, various schemes of nonadiabatic holonomic quantum computation…
Higher-order protection of quantum gates: Hamiltonian engineering coordinated with dynamical decoupling
P. Z. Zhao, Tianqi Chen, Sirui Liu +1
Dynamical decoupling represents an active approach towards the protection of quantum memories and quantum gates. Because dynamical decoupling operations can interfere with a system…
