Evolution from quantum anomalous Hall insulator to heavy-fermion semimetal in magic-angle twisted bilayer graphene
Cheng Huang, Xu Zhang, Gaopei Pan +4
The ground states of twisted bilayer graphene (TBG) at chiral and flat-band limit with integer fillings are known from exact solutions, while their dynamical and thermodynamical pr…
Optimizing for periodicity: a model-independent approach to flux crosstalk calibration for superconducting circuits
X. Dai, R. Trappen, R. Yang +12
Flux tunability is an important engineering resource for superconducting circuits. Large-scale quantum computers based on flux-tunable superconducting circuits face the problem of…
Demonstration of long-range correlations via susceptibility measurements in a one-dimensional superconducting Josephson spin chain
Daniel M. Tennant, Xi Dai, Antonio J. Martinez +20
Spin chains have long been considered an effective medium for long-range interactions, entanglement generation, and quantum state transfer. In this work, we explore the properties…
Calibration of flux crosstalk in large-scale flux-tunable superconducting quantum circuits
X. Dai, D. M. Tennant, R. Trappen +16
Magnetic flux tunability is an essential feature in most approaches to quantum computing based on superconducting qubits. Independent control of the fluxes in multiple loops is ham…
Customized quantum annealing schedules
Mostafa Khezri, Xi Dai, Rui Yang +3
In a typical quantum annealing protocol, the system starts with a transverse field Hamiltonian which is gradually turned off and replaced by a longitudinal Ising Hamiltonian. The g…
A Game Theoretic Approach to Quantum Information
Xianhua Dai, V. P. Belavkin
This work is an application of game theory to quantum information. In a state estimate, we are given observations distributed according to an unknown distribution (associated…
Additivity of Entangled Channel Capacity for Quantum Input States
V. P. Belavkin, X. Dai
An elementary introduction into algebraic approach to unified quantum information theory and operational approach to quantum entanglement as generalized encoding is given. After in…
