arXiv:2603.28894v1 Announce Type: new Abstract: We introduce a numerical tensor-network method to compute the statistics of the charge transferred across an interface partitioning an interacting one-d…
arXiv:2603.28892v1 Announce Type: new Abstract: Non-Hermitian operators naturally arise in the description of open quantum systems, which exhibit features such as resonances and decay processes, where…
arXiv:2603.28879v1 Announce Type: new Abstract: The rapid growth of machine learning is increasingly constrained by the energy and bandwidth limits of classical hardware. Optical and quantum technolog…
arXiv:2603.28877v1 Announce Type: new Abstract: The $1+1$ dimensional $\mathbb Z_2$ gauge theory is the simplest model that allows for quantum simulation to probe the fundamental aspects of a gauge th…
arXiv:2603.28870v1 Announce Type: new Abstract: We present exact, closed-form results for the non-stabilizerness of random pure states subject to a U(1) symmetry constraint. Using stabilizer entropy a…
arXiv:2603.28869v1 Announce Type: new Abstract: In this paper we propose a totally serious algorithm to solve NP problems in polynomial time provided one is willing to wager the fate of all observers …
arXiv:2603.28852v1 Announce Type: new Abstract: Syndrome extraction in the planar color code is complicated by high weight stabilizers and hook errors that can reduce the circuit-level distance. With …
arXiv:2603.28836v1 Announce Type: new Abstract: The relativistic quantum phase space (QPS) formalism extends classical phase space by incorporating both mean values and variance-covariance matrices of…
arXiv:2603.28827v1 Announce Type: new Abstract: We present a quantum-mechanical calculation of positron channeling radiation in a planar harmonic potential, explicitly accounting for the interference …
arXiv:2603.28821v1 Announce Type: new Abstract: Current quantum computers present significant noise, especially as circuit depth and qubit count increase. Prior work has demonstrated that erroneous ou…
Previously unstable relativistic systems now exhibit a discrete energy spectrum, defying the expected fall-to-the-center collapse. This transformation occurs through the imposition of a simple outgoin…

Doubling down on open-access quantum computing IBM
Generating hybrid entanglement between a qubit and squeezed multi-photon states has remained largely unexplored. This protocol reliably creates entanglement, moving beyond limitations of previous appr…
Local robust shadows on a trapped ion computer, a case study Achieving 96% fidelity in a shadow protocol represents a new balance between speed and accuracy in quantum computation. This work implement…
Until now, materials have concealed their chiral electronic band topologies from direct observation. This work reveals an integer-quantized response to light’s chirality, linking a material’s internal…
Modeling Quantum Optomechanical STIRAP A single quantum vibration can now be linked to another, creating entanglement even when starting from a defined energy state and a continuous wave of energy. Th…
Before this work, assessing whether a quantum embedding correctly separated data groups was essentially a matter of trust. Now, a new protocol allows independent verification of these mappings, even w…
Three qubits per spin is now sufficient to represent a parity Hamiltonian on a quantum annealer, a reduction from previous embedding schemes. This advance unlocks the potential implementation of the S…
Invariant measures of randomized quantum trajectories Until now, randomised quantum trajectories were generally neither φ-irreducible nor contracting, hindering predictable outcomes in quantum experim…
For a fixed number of configurations, representing quantum states becomes less accurate as their non-stabilizerness increases. This demonstrates a clear limit to how well restricted Boltzmann machines…
Optimisation algorithms typically treat parameters as flat variables, yet real-world problems often exist on complex, curved spaces. Quantum Riemannian Hamiltonian Descent achieves a convergence time …
A narrowing of probability distributions by up to twenty per cent reveals a more precise method for measuring when a quantum particle first arrives at a detector. Previously, calculations assumed each…
Lindbladian simulation now requires only O(√N) Trotter steps, a cubic improvement over previous analyses. This advance stems from newly derived commutator-based error bounds, offering a more efficient…
