Abstract Objective The outbreak of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) has caused more than 26 million cases Corona virus disease (COVID-19) in the world so far. To control spread disease, screening large numbers suspected for appropriate quarantine and treatment are a priority. Pathogenic laboratory testing is typically gold standard, but it bears burden significant false negativity, adding to urgent need alternative diagnostic methods combat disease. Based on...
Abstract Background The outbreak of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) has caused more than 2.5 million cases Corona Virus Disease (COVID-19) in the world so far, with that number continuing to grow. To control spread disease, screening large numbers suspected for appropriate quarantine and treatment is a priority. Pathogenic laboratory testing gold standard but time-consuming significant false negative results. Therefore, alternative diagnostic methods are urgently...
We introduce and explore a one-dimensional "hybrid" quantum circuit model consisting of both unitary gates projective measurements. While the are drawn from random distribution act uniformly in circuit, measurements made at positions times throughout system. By varying measurement rate we can tune between volume law entangled phase for (no measurements) "quantum Zeno phase" where strong suppress entanglement growth to saturate an area-law. Extensive numerical simulations trajectories...
In this paper we continue to explore "hybrid" quantum circuit models in one-dimension with both unitary and measurement gates, focussing on the entanglement properties of wavefunction trajectories at long times, steady state. We simulate a large class Clifford circuits, including or without randomness locations using stabilizer techniques access time dynamics systems up 512 qubits. all find volume law entangled phase for low rates, which exhibits sub-dominant logarithmic behavior entropy,...
Frustrated quantum magnets not only provide exotic ground states and unusual magnetic structures, but also support unconventional excitations in many cases. Using a physically relevant spin model for breathing pyrochlore lattice, we discuss the presence of topological linear band crossings magnons antiferromagnets. These are analogs Weyl fermions electronic systems, which dub magnons. The bulk magnon implies chiral surface forming arcs at finite energy. We argue that such antiferromagnets...
Random quantum dynamics generates error correcting codes that are robust against observers and errors. Here, the authors describe a simple physical picture of such codes, mapping characteristic code properties to statistical mechanics fluctuating ``entanglement domain walls''. The criterion is understood as decoupling condition walls, which leads universal scaling law ``code distance''.
We present random quantum circuit models for non-unitary dynamics of free fermions in one spatial dimension. Numerical simulations reveal that the tends towards steady states with logarithmic violations entanglement area law and power correlation functions. Moreover, starting a short-range entangled many-body state, dynamical evolution correlations quantitatively agrees predictions two-dimensional conformal field theory space-like time direction. argue this behavior is generic time-dependent...
Local measurements in random quantum circuits lead to a new class of ``entanglement phase transitions''. Through extensive calculations at the critical point ``stabilizer'' --- organized by mapping from finite rectangular geometry semi-infinite plane authors find here an emergent conformal field theory description entanglement dynamics, whose exponents are beyond any known theory. As we show, symmetry implies measurement-induced Bell-like nonlocality, where distant qubits become entangled...
Universal multipartite entanglement is studied for a variety of measurement induced phase transitions, exact results are presented in special case, and remarkable consistency found several different models away from this limit.
We investigate the prospects of employing linear cross-entropy to experimentally access measurement-induced phase transitions (MIPT) without requiring any postselection quantum trajectories. For two random circuits that are identical in bulk but with different initial states, $\chi$ between measurement outcome distributions acts as a boundary order parameter, and can be used distinguish volume law from area phases. In (and thermodynamic limit) measurements cannot $\chi = 1$. < Clifford...
The properties of the volume-law-entangled phase weakly monitored quantum circuits are related to classical statistical mechanics a directed polymer in random environment, shedding light on stability volume-law entanglement presence repeated projective measurements.
Topologically ordered phases are stable to local perturbations, and topological quantum error-correcting codes enjoy thresholds errors. We connect the two notions of stability by constructing classical statistical mechanics models for decoding general Calderbank-Shor-Steane linear codes. Our construction encodes correction success probabilities under uncorrelated bit-flip phase-flip errors, simultaneously describes a generalized <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"...
Quantum systems subject to random unitary evolution and measurements at points in spacetime exhibit entanglement phase transitions which depend on the frequency of these measurements. Past work has experimentally observed near-term quantum computers, but characterization approach using entropy is not scalable due exponential overhead state tomography postselection. Recently, an alternative protocol detect linear cross was proposed, attempting eliminate both bottlenecks. Here, we report...
Motivated by the recent experimental progress on strong spin-orbit-coupled rare-earth triangular antiferromagnet, we analyze highly anisotropic spin model that describes interaction between spin-orbit-entangled Kramers' doublet local moments lattice. We apply Luttinger-Tisza method, classical Monte Carlo simulation, and self-consistent wave theory to Hamiltonian. The phase diagram includes ${120}^{\ensuremath{\circ}}$ state two distinct stripe-ordered phases. frustration is very...
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 two-dimensional square lattice, perform extensive numerical studies entanglement phase transitions between volume-law and area-law entangled phases the one-dimensional boundary states. These occur when either (a) bond dimension $D$ constituent is varied, or (b) subject to breaking bulk bonds, implemented by forced measurements. In...
We study quantum circuits consisting of unitary gates, projective measurements, and control operations that steer the system towards a pure absorbing state. Two types phase transition occur as rate these is increased: measurement-induced entanglement transition, directed percolation into state (taken here to be product state). In this work we show analytically transitions are generically distinct, with trajectories becoming disentangled before reached, analyze their critical properties....
Classical shadows are a powerful method for learning many properties of quantum states in sample-efficient manner, by making use randomized measurements. Here we study the sample complexity expectation value Pauli operators via ``shallow shadows'', recently-proposed version classical which randomization step is effected local unitary circuit variable depth $t$. We show that shadow norm (the quantity controlling complexity) expressed terms Heisenberg time evolution under randomizing...
We explore a class of "open" quantum circuit models with local decoherence ("noise") and projective measurements, each respecting global Z_2 symmetry. The model supports spin glass phase where the symmetry is spontaneously broken (not possible in an equilibrium 1d system), paramagnetic characterized by divergent susceptibility, intermediate "trivial" phase. All three phases are also stable to Z_2-symmetric unitary gates, dynamical transitions between percolation universality class. open...
The authors explore critical properties of entanglement phase transitions in random tensor networks and monitored quantum circuits with Clifford tensors/gates for on-site Hilbert space dimensions which are powers a prime number $p$. Exact mappings to replica spin models characterizations their symmetry groups predict that all universal will depend only on These predictions confirmed extensive numerical simulations. also establish multifractal scaling the purity, reflected continuous spectrum...
Adaptive quantum circuits, in which unitary operations, measurements, and feedback are used to steer many-body systems, provide an exciting opportunity generate interesting dynamical steady states. We introduce adaptive dynamics with continuous symmetry where local drive ordering. In this setting, we find a pure state hosting symmetry-breaking order, is the ground of gapless, Hamiltonian. explore properties approach state. that steady-state order fragile perturbations, even those respect symmetry.
Symmetry plays a fundamental role in our understanding of both conventional symmetry breaking phases and the more exotic quantum topological matter. We explore experimental signatures enriched U(1) spin liquids (QSLs) on pyrochlore lattice. point out that Ce local moment newly discovered QSL candidate ${\mathrm{Ce}}_{2}{\mathrm{Sn}}_{2}{\mathrm{O}}_{7}$, is dipole-octupole doublet. The generic model for these unusual doublets supports two distinct ground states corresponding ice regimes....
Motivated by the recent progress in spin-orbit-coupled triangular lattice spin liquid candidate ${\mathrm{YbMgGaO}}_{4}$, we carry out a systematic projective symmetry group analysis and mean-field study of $U(1)$ spin-liquid ground states. Due to spin-orbital entanglement Yb moments, space-group operation transforms both position orientation local hence it brings different features for realization symmetries from cases with spin-only moments. Among eight liquids that find fermionic parton...
