Statistical mechanics model for Clifford random tensor networks and monitored quantum circuits
Yaodong Li, Romain Vasseur, Matthew P. A. Fisher +1
We introduce an exact mapping of Clifford (stabilizer) random tensor networks (RTNs) and monitored quantum circuits, onto a statistical mechanics model. With Haar unitaries, the fu…
Decodable hybrid dynamics of open quantum systems with Z_2 symmetry
Yaodong Li, Matthew P. A. Fisher
We explore a class of "open" quantum circuit models with local decoherence ("noise") and local projective measurements, each respecting a global Z_2 symmetry. The model supports a…
Entanglement phase transitions in random stabilizer tensor networks
Zhi-Cheng Yang, Yaodong Li, Matthew P. A. Fisher +1
We explore a class of random tensor network models with "stabilizer" local tensors which we name Random Stabilizer Tensor Networks (RSTNs). For RSTNs defined on a two-dimensional s…
Entanglement Domain Walls in Monitored Quantum Circuits and the Directed Polymer in a Random Environment
Yaodong Li, Sagar Vijay, Matthew P. A. Fisher
Monitored quantum dynamics reveal quantum state trajectories which exhibit a rich phenomenology of entanglement structures, including a transition from a weakly-monitored volume la…
