Exact solution of a boundary-driven transverse-field Ising model with hidden time-reversal symmetry
The dissipative transverse-field Ising (TFI) model provides a paradigmatic setting for nonequilibrium quantum many-body physics.On the numerical limitations of dual Koopman von Neumann embeddings for solving conservative nonlinear ordinary differential equations on quantum computers
The simulation of nonlinear ordinary differential equations on quantum computers is inherently challenging, as quantum gates are linear operators on qubit states.Decoder Model Compatibility Provides Information beyond the Logical Gap under Drifting and Correlated Quantum Noise
Quantum error-correcting decoders provide both corrections and confidence estimates for the logical-error risk of individual measurement records.Evaluation-efficient quantum architecture search with ZX-calculus-based topological reuse
Variational quantum algorithm is a leading approach for quantum chemistry and many-body physics on noisy intermediate-scale quantum devices.Amplified Memory and Finite-Time Regularity in Driven Non-Hermitian Systems
We study the roles of broken spectra and exceptional points in finite-time driven non-Hermitian fermionic dynamics.Representation-Dependent Recoverability in Quantum Compilation
Fault-tolerant compilation can disperse high-level structure: schedules split an accumulated phase across rounds, gate synthesis replaces an angle by a Clifford+$T$ word, and randomized compiling…Eigenoperator Entanglement Statistics in Local Lindbladians
Random matrix spectral statistics are widely used to diagnose quantum chaos in open systems, but whether chaotic eigenvalue correlations are accompanied by Haar-typical eigenoperators remains unclear.The Uncertainty Principle, Uncertainty Relations, and Underlying Trajectories: Feynman, Nelson, Bohm, and Persistent Kac-Dirac Dynamics
A distinction should be made between quantum uncertainty relations and the broader uncertainty principle.MagiCFirm: A Runtime for Magic-State Cultivation with Algorithm-Hardware Co-Design
Magic-state cultivation offers a promising alternative for lowering the cost of non-Clifford operations in fault-tolerant quantum computing (FTQC).A low-temperature entropy source for on-chip true random number generation: universal robustness beyond device quality
True random number generation is a critical capability for fault-tolerant quantum computing at millikelvin temperatures.QaiJi IR: An Eight-Layer Intermediate Representation Family for Hybrid Quantum-Classical Compilation
Hybrid quantum-classical compilers exchange programs among circuit, control-flow, pulse, device, and physical representations.Nonorthogonal variational quantum simulation for quantum chemistry
Dynamical simulation of quantum many-body systems is a central task in quantum chemistry and requires efficient wavefunction representations.Classical Sufficiency in Quantum Statistical Experiments
A quantum measurement transforms a quantum statistical experiment into a classical one, but different measurements generally yield experiments with different statistical information.Anisotropic information geometry of entropy production
We reveal that the information geometry of entropy production exhibits an intrinsic anisotropy, providing a unified origin for the inequivalent geometric constraints obeyed by its different…Differential hierarchy of the Husimi representation
Phase-space representations reveal the geometry of quantum mechanics and distinguish quantum features from classical ones.Evaluating the Effect of the Order of Optimization Passes in Quantum Circuit Optimization
Quantum circuit optimization is critical for mitigating the noise inherent in current quantum hardware.Fully passive monolithic silicon quantum photonic circuit for entangled photon-pair generation
Integrated quantum photonic circuits are a key enabling technology for the scalability of quantum information systems.Quantum heat transport and effects of quantum thermal devices in noncommuting coupled spins
Quantum heat transport governs energy exchange processes and statistical laws in non-equilibrium quantum systems, and plays a pivotal role in quantum thermodynamics.Optimal entanglement criteria from trace invariants
Randomized measurement protocols give experimental access to low-degree polynomial invariants of a quantum state rather than to the state itself, which raises the question of what the best…100 million photons per second from a single organic molecule
At cryogenic temperatures, organic single-photon sources (SPSs) offer Fourier-limited emission, virtually unlimited photostability, and emission wavelengths selectable by molecular design, making…
