Dissipative phase transitions and passive error correction
Yu-Jie Liu, Simon Lieu
We classify different ways to passively protect classical and quantum information, i.e. we do not allow for syndrome measurements, in the context of local Lindblad models for spin…
Bounds on Autonomous Quantum Error Correction
Oles Shtanko, Yu-Jie Liu, Simon Lieu +2
Autonomous quantum memories are a way to passively protect quantum information using engineered dissipation that creates an ``always-on'' decoder. We analyze Markovian autonomous d…
Quantum phase transition between symmetry enriched topological phases in tensor-network states
Lukas Haller, Wen-Tao Xu, Yu-Jie Liu +1
Quantum phase transitions between different topologically ordered phases exhibit rich structures and are generically challenging to study in microscopic lattice models. In this wor…
Model-Independent Learning of Quantum Phases of Matter with Quantum Convolutional Neural Networks
Yu-Jie Liu, Adam Smith, Michael Knap +1
Quantum convolutional neural networks (QCNNs) have been introduced as classifiers for gapped quantum phases of matter. Here, we propose a model-independent protocol for training QC…
Magnon squeezing enhanced entanglement in a cavity magnomechanical system
Ming-Song Ding, Ying Shi, Yu-jie Liu +1
We investigate the generation of the entanglement in a cavity magnomechanical system, which consists of three modes: a magnon mode, a microwave cavity mode and a mechanical vibrati…
Data compression for quantum machine learning
Rohit Dilip, Yu-Jie Liu, Adam Smith +1
The advent of noisy-intermediate scale quantum computers has introduced the exciting possibility of achieving quantum speedups in machine learning tasks. These devices, however, ar…
Candidate for a passively protected quantum memory in two dimensions
Simon Lieu, Yu-Jie Liu, Alexey V. Gorshkov
An interesting problem in the field of quantum error correction involves finding a physical system that hosts a ``passively protected quantum memory,'' defined as an encoded qubit…
