Optimized trajectory unraveling for classical simulation of noisy quantum dynamics

Zhuo Chen, Yimu Bao, Soonwon Choi

The dynamics of open quantum systems can be simulated by unraveling it into an ensemble of pure state trajectories undergoing non-unitary monitored evolution, which has recently be…

Diagnostics of mixed-state topological order and breakdown of quantum memory

Ruihua Fan, Yimu Bao, Ehud Altman +1

Topological quantum memory can protect information against local errors up to finite error thresholds. Such thresholds are usually determined based on the success of decoding algor…

Mixed-state topological order and the errorfield double formulation of decoherence-induced transitions

Yimu Bao, Ruihua Fan, Ashvin Vishwanath +1

We develop an effective field theory characterizing the impact of decoherence on states with abelian topological order and on their capacity to protect quantum information. The dec…

Measurement-Induced Power-Law Negativity in an Open Monitored Quantum Circuit

Zack Weinstein, Yimu Bao, Ehud Altman

Generic many-body systems coupled to an environment lose their quantum entanglement due to decoherence and evolve to a mixed state with only classical correlations. Here, we show t…

Finite-time teleportation phase transition in random quantum circuits

Yimu Bao, Maxwell Block, Ehud Altman

How long does it take to entangle two distant qubits in a quantum circuit evolved by generic unitary dynamics? We show that if the time evolution is followed by measurements of all…

The Measurement-induced Transition in Long-range Interacting Quantum Circuits

Maxwell Block, Yimu Bao, Soonwon Choi +2

The competition between scrambling unitary evolution and projective measurements leads to a phase transition in the dynamics of quantum entanglement. Here, we demonstrate that the…

Symmetry enriched phases of quantum circuits

Yimu Bao, Soonwon Choi, Ehud Altman

Quantum circuits consisting of random unitary gates and subject to local measurements have been shown to undergo a phase transition, tuned by the rate of measurement, from a state…

Theory of the phase transition in random unitary circuits with measurements

Yimu Bao, Soonwon Choi, Ehud Altman

We present a theory of the entanglement transition tuned by measurement strength in qudit chains evolved by random unitary circuits and subject to either weak or random projective…

Quantum Error Correction in Scrambling Dynamics and Measurement-Induced Phase Transition

Soonwon Choi, Yimu Bao, Xiao-Liang Qi +1

We analyze the dynamics of entanglement entropy in a generic quantum many-body open system from the perspective of quantum information and error corrections. We introduce a random…

Boundary Green functions of topological insulators and superconductors

Yang Peng, Yimu Bao, Felix von Oppen

Topological insulators and superconductors are characterized by their gapless boundary modes. In this paper, we develop a recursive approach to the boundary Green function which en…
