Error-Mitigated Quantum Gates Exceeding Physical Fidelities in a Trapped-Ion System
Shuaining Zhang, Yao Lu, Kuan Zhang +4
Various quantum applications can be reduced to estimating expectation values, which are inevitably deviated by operational and environmental errors. Although errors can be tackled…

Scalable global entangling gates on arbitrary ion qubits
Yao Lu, Shuaining Zhang, Kuan Zhang +5
A quantum algorithm can be decomposed into a sequence consisting of single qubit and 2-qubit entangling gates. To optimize the decomposition and achieve more efficient construction…
