Robust Spin Qubit Coupler via Minimal Kitaev Chain
Jiaan Qi, Hongqi Xu
While a minimal Kitaev chain is promised to host unprotected Majorana zero modes, its role for spin qubits is relatively underappreciated. Following recent breakthroughs in the fin…
Multi-qubit DC gates over an inhomogeneous array of quantum dots
Jiaan Qi, Zhi-Hai Liu, Hongqi Xu
The prospect of large-scale quantum computation with an integrated chip of spin qubits is imminent as technology improves. This invites us to think beyond the traditional 2-qubit-g…
Spin-Orbit Interaction Enabled High-Fidelity Two-Qubit Gates
Jiaan Qi, Zhi-Hai Liu, H. Q. Xu
We study the implications of spin-orbit interaction (SOI) for two-qubit gates (TQGs) in semiconductor spin qubit platforms. SOI renders the exchange interaction governing qubit pai…
Efficacy of noisy dynamical decoupling
Jiaan Qi, Xiansong Xu, Dario Poletti +1
Dynamical decoupling (DD) refers to a well-established family of methods for error mitigation, comprising pulse sequences aimed at averaging away slowly evolving noise in quantum s…
Randomized benchmarking in the presence of time-correlated dephasing noise
Jiaan Qi, Hui Khoon Ng
Randomized benchmarking has emerged as a popular and easy-to-implement experimental technique for gauging the quality of gate operations in quantum computing devices. A typical ran…
Comparing randomized benchmarking figure with average infidelity of quantum gate-set
Jiaan Qi, Hui Khoon Ng
Randomized benchmarking (RB) is a popular procedure used to gauge the performance of a set of gates useful for quantum information processing (QIP). Recently, Proctor et al. [Phys.…
