Spin-qubit noise spectroscopy from randomized benchmarking by supervised learning
Chengxian Zhang, Xin Wang
We demonstrate a method to obtain the spectra of noises in spin-qubit devices from randomized benchmarking, assisted by supervised learning. The noise exponent, which indicat…
Minimal Non-orthogonal Gate Decomposition for Qubits with Limited Control
Xiao-Ming Zhang, Jianan Li, Xin Wang +1
In quantum control theory, a question of fundamental and practical interest is how an arbitrary unitary transformation can be decomposed into minimum number of elementary rotations…
Mobility edge and intermediate phase in one-dimensional incommensurate lattice potentials
Xiao Li, S. Das Sarma
We study theoretically the localization properties of two distinct one-dimensional quasiperiodic lattice models with a single-particle mobility edge (SPME) separating extended and…
Plug-and-Play Approach to Non-adiabatic Geometric Quantum Gates
Bao-Jie Liu, Xue-Ke Song, Zheng-Yuan Xue +2
Nonadiabatic holonomic quantum computation (NHQC) has been developed to shorten the construction times of geometric quantum gates. However, previous NHQC gates require the driving…
Quantum Information Scrambling Through a High-Complexity Operator Mapping
Xiaopeng Li, Guanyu Zhu, Muxin Han +1
Quantum information scrambling has attracted much attention amid the effort to reconcile the conflict between quantum-mechanical unitarity and the thermalizaiton-irreversibility in…
Tunable charge qubit based on barrier-controlled triple quantum dots
Xu-Chen Yang, Guo Xuan Chan, Xin Wang
We present a theoretical proposal of a tunable charge qubit, hosted in triple quantum dots. The manipulation is solely performed by changing the heights of the two potential barrie…
Analytic calculation of high order corrections to quantum phase transitions of ultracold Bose gases in bipartite superlattices
Zhi Lin, Wanli Liu
We clarify some technical issues in the present generalized effective-potential Landau theory (GEPLT) that makes the GEPLT more consistent and complete. Utilizing this clarified GE…
A velocity-space adaptive unified gas kinetic scheme for continuum and rarefied flows
Tianbai Xiao, Kun Xu, Qingdong Cai
In this paper, a unified gas kinetic scheme with adaptive velocity space (AUGKS) for multiscale flow transport will be developed. In near-equilibrium flow regions, particle distrib…
Automatic spin-chain learning to explore the quantum speed limit
Xiao-Ming Zhang, Zi-Wei Cui, Xin Wang +1
One of the ambitious goals of artificial intelligence is to build a machine that outperforms human intelligence, even if limited knowledge and data are provided. Reinforcement Lear…
On the validity of microscopic calculations of double-quantum-dot spin qubits based on Fock-Darwin states
Guo Xuan Chan, Xin Wang
We consider two typical approximations that are used in the microscopic calculations of double-quantum dot spin qubits, namely, the Heitler-London (HL) and the Hund-Mulliken (HM) a…
