Kelvin-Wave Multiplication by Sound Emission
Kelvin waves are bending excitations of a quantized vortex.Cross-Platform Verification of Continuous-Variable Quantum Systems
Cross-platform verification compares output states of independently operated bosonic and quantum optical systems when classical predictions and joint measurements are unavailable.Bath-state (In)dependence of Non-Markovianity Measures in Quadratic Open Systems
Open quantum system dynamics fail to fulfill the conditions of the Markov approximation when the environment and system timescales are close to each other.Nonequilibrium statistical thermodynamics of a small quantum system coupled to quantum reservoirs
A statistical mechanical formulation where nonequilibrium averages of selected quantum observables are given exactly as averages over local density operators is used to describe the dynamics and…Non-Bloch Dynamical Quantum Phase Transitions with Memory
Dynamical quantum phase transitions (DQPTs) of periodic chains are determined by real Bloch momenta.Identifying Logical Operations from Syndrome Histories for qLDPC Codes
Syndrome histories are normally used to detect and correct errors in fault-tolerant quantum computation, but they can also reveal information about the logical operations executed during computation.Dissipative controller as a hidden source of errors in quantum gates
Quantum systems are typically controlled by classical devices that necessarily dissipate energy to the surrounding environment.Distributed Inner-Product Estimation for Continuous-Variable Quantum States
Distributed inner product estimation (DIPE) is a fundamental task in quantum information, aiming to estimate the inner product between two unknown quantum states prepared on distributed quantum…Reversible photorefractive attack in continuous-variable quantum key distribution
Quantum key distribution (QKD) offers information-theoretic security, but device imperfections introduce implementation vulnerabilities.Inevitability of the Petz transpose map
Bayes' rule is central to classical statistical inference: given a prior and a stochastic model, it determines the corresponding retrodictive conditional probabilities.A density calculus for quantum field theory
These notes provide an introduction to Haagerup noncommutative $L^p$ spaces for quantum field theorists.Detuning-assisted cavity enhancement in spectroscopy
Cavity-enhanced spectroscopy is a widely used experimental technique.Stabilizing fluctuating Cooper pairs with a terahertz resonator
Coupling quantum materials to electromagnetic cavities or resonators without external driving has gained prominence as a new control mechanism.Three-dimensional QCA that are not stably circuits
We prove that the three-dimensional chiral $\Z_p$ Clifford quantum cellular automata of Haah and of Sun--Yang--Wang--Tantivasadakarn--Chen are, for every odd prime $p$, not finite-depth quantum…Bounds for General $(r,δ)$-Quantum Locally Recoverable Codes
We study general $(r,δ)$-quantum locally recoverable codes (qLRCs) without assuming purity or a stabilizer structure, and with arbitrarily overlapping recovery blocks.Bulk gap stability and spectral flow for fermions with weak long-range interactions
We prove that weak long-range many-body interactions preserve the bulk gap of a free fermion system and that a quasi-local spectral flow transports the free ground state to ground states of the…Transport in spinful non-Hermitian gauge lattices
We extend the generalized transfer-matrix method introduced in [H.QDMin: Coherent Quantum Minimum Finding for Nuclear Deformation Landscapes
Locating the minimum of a nuclear collective landscape can require many interacting many-body calculations.High-Fidelity Universal Quantum Gates in a Cryogenic Atom Array
Neutral atoms in optical tweezer arrays have emerged as a leading platform for quantum information processing.Local determination of low-energy states in gapped fermion systems with weak long-range interactions
We consider bulk-gapped fermion systems whose infinite-volume bulk is obtained by adding sufficiently weak even many-body interactions to a free Hamiltonian with spectral gap $g>0$, allowing…
