A Restricted Boltzmann Machine with Quantum-State Visible Units
Zhe-Hao Zhang, Yi-Cong Yu, Xiaoming Cai +1
We construct a restricted Boltzmann machine (RBM) whose visible input is a quantum state rather than a classical configuration. Each hidden unit carries a trainable quantum templat…
Localization Tensor Revisited: Geometric-Probabilistic Foundations and a Structure-Factor Criterion under Periodic Boundaries
Zhe-Hao Zhang, Xiaoming Cai, Yi-Cong Yu
We revisit the localization tensor (LT) from geometric and probabilistic perspectives and construct extensions that are naturally compatible with periodic boundary conditions (PBC)…
Universal Properties of Critical Mixed States from Measurement and Feedback
Zhehao Zhang, Yijian Zou, Timothy H. Hsieh +1
We explore the universal properties of mixed quantum matter obtained from "single-shot" adaptive evolution, in which a quantum-critical ground-state is manipulated through a single…
Non-onsite symmetry breaking: topological phase coexistence and criticality
Zhehao Zhang, Yabo Li, Tsung-Cheng Lu
We explore the states of matter arising from the spontaneous symmetry breaking (SSB) of non-onsite symmetries. In one spatial dimension, we construct a frustration-f…
Quantum Communication and Mixed-State Order in Decohered Symmetry-Protected Topological States
Zhehao Zhang, Utkarsh Agrawal, Sagar Vijay
Certain pure-state symmetry-protected topological orders (SPT) can be used as a resource for transmitting quantum information. Here, we investigate the ability to transmit quantum…
Microscopic origin of quantum supersonic phenomenon in one dimension
Zhe-Hao Zhang, Yuzhu Jiang, Hai-Qing Lin +1
Using the Bethe ansatz (BA), we rigorously obtain non-equilibrium dynamics of an impurity with a large initial momentum in the one-dimensional (1D) interacting bosonic medium.…
Mixed-state long-range order and criticality from measurement and feedback
Tsung-Cheng Lu, Zhehao Zhang, Sagar Vijay +1
We propose a general framework for using local measurements, local unitaries, and non-local classical communication to construct quantum channels which can efficiently prepare mixe…
The X-Cube Floquet Code
Zhehao Zhang, David Aasen, Sagar Vijay
Inspired by the coupled-layer construction of the X-Cube model, we introduce the X-Cube Floquet code, a dynamical quantum error-correcting code where the number of encoded logical…
