This paper demonstrates a quantum advantage in strong coin flipping—a cryptographic primitive for distrustful parties—by experimentally implementing a protocol using a deterministic quantum dot single-photon source that outperforms both classical methods and previous faint-laser pulse implementations.
This paper proposes a novel approach to quantum state tomography that reconstructs the state of an open quantum system by measuring transport currents and their correlations, establishing an exact link between these observables and the system's Lindbladian dynamics to enable state certification and entanglement detection without requiring isolation from environmental dissipation.
This paper presents experimental and theoretical evidence for the formation of three-atom-thick gold structures in break-junction systems and introduces a robust method for calibrating atomic-scale distances and assessing electrode sharpness using these structures as a benchmark.
This paper establishes that macroscopic superconducting coherence in hybrid normal-superconducting devices governs deviations from standard thermodynamic uncertainty relations in the subgap regime, leading to the derivation of a generalized quantum uncertainty bound for the Andreev regime that remains universally valid.
This paper investigates finite-size effects in thin films of nodal line semimetals, demonstrating that hybridization of drumhead and bulk surface states can drive transitions into lower-dimensional nodal lines, partially gapped phases with 2D Weyl cones, or fully gapped topological phases characterized by thickness-dependent invariants.
This study demonstrates two Hahn echo-based quantum sensing protocols using molecular spins (VO(TPP) and VOPt(SOCPh)₄) embedded in a superconducting resonator to discriminate time-dependent magnetic fields without periodicity matching, achieving sensitivities down to approximately for microsecond-duration signals.
This study reveals that the finite thickness of quasi-2D Weyl semimetal systems induces a crossover from 2D quantum Hall universality to 3D Gaussian Unitary Ensemble behavior, suggesting that such auxiliary degrees of freedom may explain existing discrepancies in universal critical exponents.
This paper proposes and analyzes measurement-powered quantum tunneling engines that utilize the energy exchange from detecting virtually occupied states to simultaneously generate power and achieve autonomous refrigeration, while also demonstrating a "purification-by-noise" effect that drives the system into a stationary dark state.
This paper investigates a Duffing resonator under bichromatic excitation, revealing how the competition between two drives in the slow-beating regime induces dynamical phase transitions between coexisting states, which are characterized by a cycle-averaged amplitude order parameter and mapped to provide a framework for controlling nonlinear systems across various platforms.
This paper investigates how an orbital magnetic field induces gap-opening and layered Chern insulating states in lattice-based Weyl semimetals, revealing rich phenomenology driven by cone anisotropy and distinct surface Fermi-arc evolution that differs from continuum predictions.
