Capturing Open Quantum System Dynamics with Compact Dressed Hamiltonians
We advance the compact dressed Hamiltonian (CDH) framework to simulate the dynamics of open quantum systems strongly coupled to structured bosonic environments.Hidden parabolic subgroups of $\mathrm{GL}_n$ over finite chain rings
We give a bounded-error quantum polynomial-time algorithm for finding hidden parabolic subgroups of $\mathrm{GL}_n(R)$ over any effectively presented finite chain ring $R$.Stable charged energy and phase transitions in an anisotropic Dicke quantum battery with Kerr nonlinearity
Phase transitions (PTs) in quantum many-body systems offer a powerful route to manipulate the performance of quantum batteries (QBs).Orbital-angular-momentum control of localized Floquet states and photocurrents in Weyl semimetals
Structured light provides a route to controlling quantum materials not only through its polarization, but also through its spatial profile and orbital angular momentum (OAM).Scrambling Separates Superradiance from Quantum Chaos
Early studies on the Dicke model linked superradiance to quantum chaos, whereas later anisotropic Dicke and Rabi studies reached apparently conflicting conclusions.Chaos and scrambling in anisotropic Dicke and Rabi models
Identifying the quantum signatures of classical chaos remains a central question in quantum physics, and quantum scrambling provides a new perspective on this correspondence.Quantum Simulation of the Static Yukawa Model via Effective Particles on a Trapped-Ion Quantum Simulator
Trapped-ion, neutral-atom, and circuit QED quantum computers naturally enable coupled qubit-boson simulations.Tuning between collective dynamics and scrambling through initial-state symmetry alignment in long-range spin models
Long-range interactions in many-body quantum systems give rise to a wide range of dynamical phenomena, from collective dynamics well described by integrable mean-field models with symmetric…Efficient Ground-State Manifold Amplification for Rydberg Atom Arrays via Houdayer Cluster Updates
We demonstrate a hybrid quantum-classical approach for exploring ground-state manifolds of maximum independent set problems, in which quantum hardware supplies the initial solutions and an entirely…NeST: ultra-high-rate qLDPC codes with sub-$50μ$s stabiliser cycles via spin shuttling
Quantum low-density parity-check codes now reach encoding rates up to 50% at useful distances.Entanglement Distribution in Quantum Switch Networks: Memory Limits and Achievability
We study the minimum persistent memory required to distribute a graph state through a quantum switch.Complete Modified Logarithmic Sobolev Inequalities for one-dimensional quantum Spin Chain
We prove a complete modified logarithmic Sobolev inequality with a system-size-independent constant for Chen--Kastoryano--Gilyén Gibbs samplers on one-dimensional spin chain at every fixed positive…Cumulative locality governs collective quantum charging
Quantum batteries can outperform their classical counterparts through collective quantum effects, yet the conditions enabling such advantage remain unclear.Characterizing supersolid phase transitions in trapped quantum gases with tilted dipoles at finite temperature
Motivated by a recent experimental work arXiv:2608.20327, we theoretically investigate the nature of phase transitions in a trapped dipolar quantum gas upon tuning the contact interaction strength…Separability does not certify zero-noise extrapolation: Factorial diagnostics in dynamic quantum circuits
Separately amplifying gate, latency, and mid-circuit measurement errors can simplify zero-noise extrapolation, but a weak interaction between amplification knobs does not establish an accurate…Interacting quantum reference frames
We formulate quantum reference frames within the Dirac quantization of gauge theories, where physical states are obtained from a kinematical Hilbert space $\mathcal{H}_{\rm kin}$ by group averaging.Local Clifford equivalence to CSS codes: Polynomial-time classification and conversion
Calderbank--Shor--Steane (CSS) codes support decoding and fault-tolerant logical operations through separate pure $X$ and pure $Z$ stabilizer checks.CoDecoder: Make Quantum Decoders Up to 100x Faster and Even More Accurate
Fault-tolerant quantum computers need fast and accurate error decoding.Bias-Preserving Entanglement of Kerr-Cat Qubits with an ATS Coupler
Kerr-cat qubits offer a hardware-efficient route to fault-tolerant quantum computing by suppressing bit-flip errors exponentially, while phase-flip errors increase only linearly with the mean photon…Lamb shift of rotational energy levels in quantum gravity
One of the major challenges of modern foundational physics is the combination of quantum physics and general relativity into a theory of quantum gravity.
