We numerically study the measurement-driven quantum phase transition of Haar-random quantum circuits in $1+1$ dimensions. By analyzing the tripartite mutual information we are able to make a precise estimate of the critical measurement rate $p_c = 0.17(1)$. We extract estimates for the associated bulk critical exponents that are consistent with the values for percolation, as well as those for stabilizer circuits, but differ from previous estimates for the Haar-random case. Our estimates of the…

Measurement-induced criticality and entanglement clusters: A study of one-dimensional and two-dimensional Clifford circuits
Entanglement transitions in quantum dynamics present a novel class of phase transitions in nonequilibrium systems. When a many-body quantum system undergoes unitary evolution interspersed with
Probing sign structure using measurement-induced entanglement
The sign structure of quantum states is closely connected to quantum phases of matter, yet detecting such fine-grained properties of amplitudes is subtle. Here we employ as a diagnostic
Quantum Coding with Low-Depth Random Circuits
TLDR
It is found that for any rate beneath the capacity, high-performing codes with thousands of logical qubits are achievable with depth 4-8 expurgated random circuits in $D=2$ dimensions.
Topological order and entanglement dynamics in the measurement-only XZZX quantum code
We examine the dynamics of a (1 + 1) -dimensional measurement-only circuit defined by the stabilizers of the [[5,1,3]] quantum error correcting code interrupted by single-qubit Pauli measurements. The
Dynamical Purification Phase Transition Induced by Quantum Measurements
Continuously monitoring the environment of a quantum many-body system reduces the entropy of (purifies) the reduced density matrix of the system, conditional on the outcomes of the measurements. We
Decoding the Entanglement Structure of Monitored Quantum Circuits
Given an output wavefunction of a monitored quantum circuit consisting of both unitary gates and projective measurements, we ask whether two complementary subsystems are entangled or not. For
Statistical Mechanics Model for Clifford Random Tensor Networks and Monitored Quantum Circuits
We study entanglement transitions in Clifford (stabilizer) random tensor networks (RTNs) and monitored quantum circuits, by introducing an exact mapping onto a (replica) statistical mechanics model.
Robust decoding in monitored dynamics of open quantum systems with Z_2 symmetry
We explore a class of “open” quantum circuit models with local decoherence (“noise”) and local projective measurements, each respecting a global Z2 symmetry. The model supports a spin glass phase
Measurement-induced phase transitions in sparse nonlocal scramblers
TLDR
This work considers sets of deterministic sparse couplings that naturally interpolate between local circuits that slowly scramble information and highly nonlocal circuits that achieve the fast-scrambling limit, and finds that circuits featuring sparse nonlocal interactions are able to withstand substantially higher rates of local measurement than circuits with only local interactions.
Entanglement Negativity at Measurement-Induced Criticality
We propose entanglement negativity as a fine-grained probe of measurement-induced criticality. We motivate this proposal in stabilizer states, where for two disjoint subregions, comparing their

Characterizing how entanglement grows with time in a many-body system, for example after a quantum quench, is a key problem in non-equilibrium quantum physics. We study this problem for the case of

TLDR
As an application, the exact value sqrt[3]/2 is computed for the conductivity at the spin Hall transition, as well as the shape dependence of the mean conductance in an arbitrary simply connected geometry with two extended edge contacts.

It is found that the entanglement spectrum of a subsystem evolves with three distinct timescales, and features hold for chaotic Hamiltonian and Floquet dynamics as well as a range of quantum circuit models.

The Gottesman-Knill theorem, which says that a stabilizer circuit, a quantum circuit consisting solely of controlled-NOT, Hadamard, and phase gates can be simulated efficiently on a classical computer, is improved in several directions.
