Energy spectrum, exchange interaction and gate crosstalk in a pair of double-quantum-dot system: a molecular orbital calculation
Xu-Chen Yang, Xin Wang
We present a theoretical study of a four-electron four-quantum-dot system based on molecular orbital methods, which hosts a pair of singlet-triplet spin qubits. We explicitly take…
Benchmarking of dynamically corrected gates for the exchange-only spin qubit in noise environment
Chengxian Zhang, Xu-Chen Yang, Xin Wang
We study theoretically the responses of the dynamically corrected gates to time-dependent noises in the exchange-only spin qubit system. We consider noises having spectra pro…
Noise filtering of composite pulses for singlet-triplet qubits
Xu-Chen Yang, Xin Wang
Semiconductor quantum dot spin qubits are promising candidates for quantum computing. In these systems, the dynamically corrected gates offer considerable reduction of gate errors…
Fast control of semiconductor qubits beyond the rotating-wave approximation
Yang Song, J. P. Kestner, Xin Wang +1
We present a theoretical study of single-qubit operations by oscillatory fields on various semiconductor platforms. We explicitly show how to perform faster gate operations by goin…
