Open system quantum dynamics can generate a variety of long-range entangled mixed
states, yet it has been unclear in what sense they constitute phases of matter. To establish …

We propose a general framework for using local measurements, local unitaries, and
nonlocal classical communication to construct quantum channels, which can efficiently …

We study states with intrinsic topological order subjected to local decoherence from the
perspective of separability, ie, whether a decohered mixed state can be expressed as an …

We study quantum many-body mixed states with a symmetry from the perspective of
separability, ie, whether a mixed state can be expressed as an ensemble of short-range …

We study the entanglement structure of topological orders subject to decoherence on the
bipartition boundary. Focusing on the toric codes in d space dimensions for d= 2, 3, 4, we …

Entanglement, measurement, and classical communication together enable teleportation of
quantum states between distant parties, in principle, with perfect fidelity. To what extent do …

Defects are common in physical systems with boundaries, impurities or extensive
measurements. The interaction between bulk and defect can lead to rich physical …

Quantum critical systems constitute appealing platforms for exploring novel measurement-
induced phenomena due to their innate sensitivity to perturbations. We study the impact of …

The entanglement entropy (EE) of the ground state of a one-dimensional Hamiltonian at
criticality has a universal logarithmic scaling with a prefactor given by the central charge c of …

Entanglement in quantum many-body systems can exhibit universal phenomena governed
by long-distance properties. We study universality and phase transitions of the entanglement …
