Coherence Protection for Mobile Spin Qubits in Silicon
Jan A. Krzywda, Yuta Matsumoto, Maxim De Smet +6 more·Feb 9, 2026
Mobile spin qubit architectures promise flexible connectivity for efficient quantum error correction and relaxed device layout constraints, but their viability rests on preserving spin coherence during transport. While shuttling transforms spatial di...
Majorana zero modes in superconductor-magnet heterostructures with d-wave order
Bastien Fajardo, T. Pereg-Barnea, Arun Paramekanti +1 more·Feb 9, 2026
Magnetic skyrmions in proximity to superconductors offer a route to engineering topological superconductivity due to the synthetic spin-orbit coupling engendered by the spin twist of the skyrmion texture. Previous theoretical works show that this lea...
Quantum annealing and condensed matter physics
Viv Kendon, Nicholas Chancellor·Feb 9, 2026
Quantum annealing leverages the properties of interacting quantum spin systems to solve computational problems, typically optimisation problems. Current hardware now has capabilities that can be used to solve condensed matter physics problems, too. I...
Quantum State Characterization of Gravitational Waves via Graviton Counting Statistics
Kristian Toccacelo, Thomas Beitel, Ulrik Lund Andersen +1 more·Feb 9, 2026
Although gravitational waves are now routinely observed, the detection of individual gravitons has long been regarded as impossible. Recent work, however, has demonstrated that single-graviton detection can be achieved and may be feasible in the near...
Quantum Phaselift
Dhrumil Patel, Laura Clinton, Steven T. Flammia +1 more·Feb 9, 2026
Estimating quantum time-series such as the Loschmidt amplitude $f(t)=\langleψ|\mathrm{e}^{-\mathrm{i}Ht}|ψ\rangle$ is central to spectroscopy, Hamiltonian analysis, and many phase-estimation algorithms. Direct estimation via the Hadamard test require...
Negative Hybridization: a Potential Cure for Braiding with Imperfect Majorana Modes
Cole Peeters, Themba Hodge, Stephan Rachel·Feb 9, 2026
Majorana zero modes, the elementary building blocks for the quantum bits of topological quantum computers, are known to suffer from hybridization as their wavefunctions begin to overlap. This breaks the ground state degeneracy, splitting their energy...
Constant-space-overhead fault-tolerant quantum input/output and communication
Paula Belzig, Hayata Yamasaki·Feb 9, 2026
Fault-tolerant capacities quantify the ability of a quantum channel to reliably transmit information when every component of the encoding and decoding procedure is noisy. Earlier work analyzed achievable communication rates under such noise using fau...
Area Scaling of Dynamical Degrees of Freedom in Regularised Scalar Field Theory
Oliver Friedrich, Kristina Giesel, Varun Kushwaha·Feb 9, 2026
How many canonical degrees of freedom does a quantum field theory actually use during its Hamiltonian evolution? For a UV/IR-regularised classical scalar field, we address this question directly at the level of phase-space dynamics by identifying the...
Anomalous spin transport in integrable random quantum circuits
Songlei Wang, Chenguang Liang, Hongzheng Zhao +1 more·Feb 9, 2026
High-temperature spin transport in integrable quantum spin chains exhibits a rich dynamical phase diagram, including ballistic, superdiffusive, and diffusive regimes. While integrability is known to survive in static and periodically driven systems, ...
Surface code off-the-hook: diagonal syndrome-extraction scheduling
Gilad Kishony, Austin Fowler·Feb 9, 2026
In the rotated surface code, hook errors (errors on auxiliary qubits midway through syndrome extraction that propagate to correlated two-qubit data errors) can reduce the circuit-level code distance by a factor of two if the extraction schedule is po...
Volume-law protection of metrological advantage
Piotr Wysocki, Jan Chwedeńczuk, Marcin Płodzień·Feb 9, 2026
Although entanglement can boost metrological precision beyond the standard quantum limit, the advantage often disappears with particle loss. We demonstrate that scrambling safeguards precision by dispersing information about the encoded parameter int...
Universality classes split by strong and weak symmetries
Jongjun M. Lee, Myung-Joong Hwang, Igor Boettcher·Feb 9, 2026
Dissipative phase transitions are strongly shaped by the symmetries of the Liouvillian, yet the quantitative impact of weak and strong symmetries on critical behavior has remained unclear. We study a squeezed-photon model with single- and two-photon ...
Eigenstate Thermalization for Local versus Translationally Invariant Observables
Rohit Patil, Marcos Rigol·Feb 9, 2026
Local observables and their translationally invariant counterparts are generally thought as providing the same predictions for experimental measurements. This is used in the context of their expectation values, which are indeed the same in clean syst...
Quantum-Inspired Self-Attention in a Large Language Model
Nikita Kuznetsov, Niyaz Ismagilov, Ernesto Campos·Feb 9, 2026
Recent advances in Natural Language Processing have been predominantly driven by transformer-based architectures, which rely heavily on self-attention mechanisms to model relationships between tokens in a sequence. Similarly, the field of Quantum Nat...
Hybrid Method of Efficient Simulation of Physics Applications for a Quantum Computer
Carla Rieger, Albert T. Schmitz, Gehad Salem +5 more·Feb 9, 2026
Quantum chemistry and materials science are among the most promising areas for demonstrating algorithmic quantum advantage and quantum utility due to their inherent quantum mechanical nature. Still, large-scale simulations of quantum circuits are ess...
Cascaded Optomechanical Sensing for Small Signals
Marta Maria Marchese, Daniel Braun, Stefan Nimmrichter +1 more·Feb 9, 2026
We propose a sensing scheme for detecting weak forces that achieves Heisenberg-limited sensitivity without relying on entanglement or other non-classical resources. Our scheme utilizes coherent averaging across a chain of N optomechanical cavities, u...
