Leakage and sweet spots in triple-quantum-dot spin qubits: A molecular-orbital study
Chengxian Zhang, Xu-Chen Yang, Xin Wang
A triple-quantum-dot system can be operated as either an exchange-only qubit or a resonant-exchange qubit. While it is generally believed that the decisive advantage of the resonan…
Fast pulse sequences for dynamically corrected gates in single-triplet qubits
Robert E. Throckmorton, Chengxian Zhang, Xu-Chen Yang +3
We present a set of experimentally feasible pulse sequences that implement any single-qubit gate on a singlet-triplet spin qubit and demonstrate that these new sequences are up to…
Randomized benchmarking of barrier versus tilt control of a singlet-triplet qubit
Chengxian Zhang, Robert E. Throckmorton, Xu-Chen Yang +3
Decoherence due to charge noise is one of the central challenges in using spin qubits in semiconductor quantum dots as a platform for quantum information processing. Recently, it h…
