Dualities in one-dimensional quantum lattice models: Lie groups, Schur-Weyl duality and symmetry breaking
We present a systematic framework for gauging continuous symmetries, and show that the Schur-Weyl duality arises naturally as a realization of this construction with open boundary conditions.Beyond Quantum Messages: Toward Quantum-Native Network Functioning
The Quantum Internet is commonly envisioned as a network that transports quantum states and distributes entanglement as the key resource underpinning distributed quantum applications.Recovery gates as a resource in repetition-code process tomography: exhaustive gate-optimal designs for three, five and seven qubits
Process tomography built on stabilizer codes compares the logical channel of a repetition code with a reference channel, and the decoder that produces that channel is almost always fixed to the…Testing Gravitationally-Induced-Entanglement with Massive Particles and Quantum Clocks
We present an experimental proposal to test whether gravity can entangle a levitated particle with an array of quantum clocks.Atomic Static Electric Quadrupole Polarizability from Relativistic Many-Body Theory With Application To Thulium $\left(6s^2\, 4f^{13}\right)$\, $^2F_{7/2}$ and $^2F_{5/2}$
In the present work a method for calculating atomic static electric rank-$n$ tensor quadrupole polarizabilities $α_Q^{(n)}(J)$ for arbitrary atomic electronic structure is presented.Asymptotic analysis of the dynamical field-field correlation function of the impenetrable Bose gas
We study the long-time, large-distance asymptotic behaviour of the two-point correlation function of fields of the impenetrable Bose gas in equilibrium states characterized by a quasi-momentum…Recalibration-Aware Optimization of ZEFOZ Operating Points in $^{167}\mathrm{Er}^{3+}:\mathrm{Y}_2\mathrm{SiO}_5$ for Quantum Memories
Erbium-doped solids like $^{167}\mathrm{Er}^{3+}:\mathrm{Y}_2\mathrm{SiO}_5$ have properties that make them suitable for quantum-network memories, however, their unquenched effective electronic spin…Disorder-blind Mpemba acceleration of quantum state preparation
Using the strong Mpemba effect to accelerate relaxation by initial-state design requires suppressing the slowest mode, which typically needs prior knowledge of the system.Quantum enhanced beam displacement estimation: sensitivity limits, optimal probes, and measurement schemes
We investigate the ultimate sensitivity limits for measuring small transverse beam displacements and identify optimal strategies that attain them, using the framework of mode parameter estimation.DiffSequence-Q: Diffusion Design with Quantum Assistance for Biologically Active Proteins
Designing protein sequences that satisfy both secondary structure requirements and solubility targets remains challenging.Polynomial-time classical simulation of boson and fermion sampling under thermal loss
Sampling experiments are a leading approach to demonstrating quantum computational advantage, yet their robustness to experimental noise is not completely understood.Dynamical effects induced by synthetic SU(1,1) gauge fields
Compact gauge fields are powerful tools for controlling quantum dynamics and topological phases of matter.Room-Temperature Quantum Emission from Boron Nitride Nanotubes
Quantum information systems such as quantum key distribution and quantum communications require bright, high-purity, stable sources of single photons to act as carriers of quantum information.Quantum Knowledge Distillation: State-of-the-art, Applications and Open Problems
Knowledge distillation transfers predictions, representations, or other supervisory information between learning models and is increasingly investigated in quantum machine learning.Provable circuit-level thresholds for non-abelian topological phases
We provide an explicit scheme to realize a quantum memory in any 2D non-chiral topological order.Static and dynamical Casimir effects in a wedge within the worldline formulation
We study a real massless scalar field in $d+1$ dimensions confined to a wedge of opening angle $α$, in the presence of a semitransparent circular arc that may oscillate radially.Exact teleportation bounds for fermionic Hawking thermality beyond the single-mode approximation
Fermionic teleportation near a Schwarzschild horizon involves two physically distinct ingredients that are often varied together: Hawking thermal mixing and the relative composition of the right and…Coherence Spreading Law in Quenched Homogeneous Bose Gases
We investigate nonequilibrium coherence spreading in quenched homogeneous bosonic gases both analytically and numerically.Emergent Incompressibility in Polariton Condensates for Scalable XY Spin Simulation
Driven-dissipative polariton networks offer a powerful analog platform for simulating continuous-spin Hamiltonians.Structural Lower Bounds for Quantum Property Estimation with Persistent Memory
In quantum property estimation, an experimenter estimates $\operatorname{Tr}(Oρ)$ for a family of observables from independent copies of an unknown state $ρ$ simultaneously to additive error $ε$.
