Coupling two charge qubits via a superconducting resonator operating in the resonant and dispersive regimes
Chengxian Zhang, Guo Xuan Chan, Xin Wang +1
A key challenge for semiconductor quantum-dot charge qubits is the realization of long-range qubit coupling and performing high-fidelity gates based on it. Here, we describe a new…
Charge noise suppression in capacitively coupled singlet-triplet spin qubits under magnetic field
Guo Xuan Chan, Jason P. Kestner, Xin Wang
Charge noise is the main hurdle preventing high-fidelity operation, in particular that of two-qubit gates, of semiconductor-quantum-dot-based spin qubits. While certain sweet spots…
Implementation of geometric quantum gates on microwave-driven semiconductor charge qubits
Chengxian Zhang, Tao Chen, Xin Wang +1
A semiconductor-based charge qubit, confined in double quantum dots, can be a platform to implement quantum computing. However, it suffers severely from charge noises. Here, we pro…
High-fidelity geometric gate for silicon-based spin qubits
Chengxian Zhang, Tao Chen, Sai Li +2
High-fidelity manipulation is the key for the physical realization of fault-tolerant quantum computation. Here, we present a protocol to realize universal nonadiabatic geometric ga…
