Fast Random Compilers for Time-Dependent and Time-Independent Lindbladian Simulation
Randomized product formulas provide simple and flexible methods for quantum simulation.Do Neural Networks Learn Structure-Preserving Maps? A Case Study in Latent-to-Hilbert Embeddings
We ask whether a neural network can learn a structure-preserving map from a compressed latent space to a Hilbert-space representation.Demonstration of a Structured Agentic Workflow for Applied Quantum Computing Research
Quantum hardware advances now make it practical to explore quantum approaches to scientific problems.Lifted surgery for non-Abelian two-block group-algebra codes
Code surgery measures a logical operator of a quantum LDPC code with $O(d)$ rounds of syndrome extraction.Shallow Quantum Circuits for Geometrically Local Lindblad Dynamics
Open-system dynamics govern decoherence, transport, and engineered dissipation in quantum many-body systems.Minimax Quantum State Tomography in a Known Trace-Distance Ball
We study quantum state tomography when the unknown state lies in a trace-distance ball of radius $R$ around a known reference state $ρ$.On State Distinguishing Without Inverse Queries
In the quantum state distinguishing problem, an algorithm is given copies of a state $|ψ\rangle$ or $|φ\rangle$ separated by trace distance $\varepsilon$, and tasked with deciding which is the case.Walk/Zeta correspondence for quantum walks on path graphs: a pre-geometric structure implied by a generalized reflection principle
We establish a local Konno-Sato correspondence for reflected random and Szegedy walks on a finite path graph.Performance Analysis of Multiparty GHZ-State Quantum Conference Key Agreement over Optical Fiber Channel
Quantum conference key agreement (QCKA) enables multiple spatially separated users to establish a common key with composable information-theoretic security by exploiting multipartite quantum…Game of Nons: Non-Gaussian Nonunitary Environments with Nonlinear Coupling
We develop a perturbative framework for systems coupled quadratically to bosonic environments with quadratic Hamiltonians and linear Lindblad operators.Spin-orbit-induced gauge field and spin Hall effects in quasi-paraxial fluids of light
We show that quasi-paraxial fluids of light propagating in nonlinear Kerr media naturally experience an effective gauge field arising from the intrinsic spin-orbit interaction of light encoded in…Nonlinear quantum multi-spin dynamics without entanglement
We introduce a distinct route for extending classical atomistic spin dynamics into the quantum regime for arbitrary spin $s$, based on a variational product-state \textit{ansatz} that includes both…Optimization Geometry of QAOA and Variational Quantum Algorithms
Variational quantum algorithms turn choices of Hamiltonian, ansatz, and parameterization into a classical nonconvex optimization problem.Optimal and Verifiable Quantum Advantages in Communication Complexity
We establish optimal quantum-classical separations in communication complexity for search problems.Autonomous Quantum Memories from Classical Stochastic Processes
The study of quantum memories out of thermal equilibrium is motivated both by the need for memories that withstand realistic noise in fault-tolerant quantum computers and by the fundamental question…Erasure of entanglement-locked energy in multi-cell quantum batteries through decoherence
Charging a quantum battery through a pumped charger can lock a substantial part of its stored energy inside the bipartite correlations that grow between the constituent cells, and this…A solvable quantum many-body problem
A many-body wavefunction exponential in R, where the square of R is the sum of the squares of the interparticle distances, is shown to be the solution of Schrodingers equation for a potential…Frame-dependent coherence of Gaussian quantum states
A Hilbert space is usually described using an orthonormal basis, but a more general description can be defined using a tight frame.Ground state energy estimation and preparation by the truncated power method
The Guided Local Hamiltonian Problem (GLHP) is the problem of ground state energy estimation and preparation given a guiding state having good overlap with the true ground state.Simultaneous Circuit Tests for Finite Reversible Models of Quantum Control
A finite reversible model can approximate individual quantum gates while retaining freedom in its transition tables and preparation contexts.
