Pushing beyond the memory barrier in propagation algorithms with randomization
Performant classical tools for simulating quantum circuits are important for benchmarking and supporting upcoming quantum devices.Methods for Deriving Nonlinear Kinetic Equations from the Dynamics of Quantum Systems
The article outlines key topics related to deriving kinetic equations and, in general, to the relationship between the evolution equations governing quantum many-particle systems.Tunable flat bands from a parent chiral Hamiltonian
Systems with flat bands are interesting as they potentially host many exotic quantum phenomena that would be hard to observe in usual systems with dispersive bands.The Prevalence of Straight Shots in Control Space for Reaching Optimal Quantum Performance
Gradient-based algorithms are often applied to identify an optimal control for maximizing a quantum objective functional by following a steepest ascent path to the top of the control landscape.Engineering Low-Latency, High-Throughput Quantum Decoders on NVIDIA GPUs
We design and optimize a quantum error correction (QEC) decoder for NVIDIA GPUs, combining Relay belief propagation, a state-of-the-art message-passing algorithm, with order-zero ordered statistics…From Qubit Tensorization to Gaussian Optimizers in Bosonic Systems
We develop a method for deriving Gaussian optimality results for bosonic quantum systems from inequalities for qubit systems.Lieb-Robinson bounds via the Combes-Thomas estimate
This paper studies quantum spin systems: networks of spins coupled by local interactions.Can Quantum Layers offer Performance and Security Advantages in Vision-Language Models?
As quantum computing moves from the noisy intermediate-scale quantum (NISQ) era toward early fault-tolerant quantum computing (EFTQC), quantum-enhanced AI is shifting from a conceptual idea to…Digital Quantum Simulation of Dynamics in Interacting Fields
Matter under extreme conditions behaves as a non-equilibrium, strongly-interacting quantum system.Verified Pauli-Product Measurement Compilation for Fault-Tolerant Quantum Computation
Fault-tolerant quantum compilers implement gates through Pauli-product measurements and classical feedback.Quantum State Search with Classical Interactive Advice
We study whether a quantum verifier can find a hidden quantum state by exchanging classical messages with an unbounded prover who knows the state.Subsystem quantum Rényi-Bhattacharyya distance in 2D CFTs and its holographic applications
We develop a systematic method to compute the subsystem fidelity and Rényi fidelity in two-dimensional conformal field theories (CFTs) from the operator product expansion of twist operators, and…Distributed Phase Tags: A Locality-Preserving Realification Compiler for Misty-State Quantum Programs
Complex amplitudes can be simulated over real Hilbert spaces by adjoining a two-dimensional real/imaginary degree of freedom.Measuring the Quantum Phase of Multiphoton Systems
The quantum phase of a multiparticle system has remained a long-standing mystery in quantum physics.Perturbation theory for quantum information quantities of Gaussian states
Many quantum-information tasks can benefit from Gaussian quantum resources, while their fundamental performance limits are characterized by quantum information quantities.Online Scheduling and Distribution of Quantum Circuits over Quantum Networks
Emerging quantum networks enable distributed quantum computing (DQC) by interconnecting modest, noisy quantum processors.Non-planar contact structures with Calabi-Yau Fillings and topological quantum computation
This paper is a non-planar counterpart of the author's earlier work on planar contact structures and topological quantum computation.Quantum computing for plasma physics in magnetic-confinement fusion
Plasma simulations for magnetic-confinement fusion (MCF) involve high-dimensional kinetic dynamics, strong nonlinear coupling, complex geometries, and multiscale spatiotemporal behavior, imposing…How Quantum Is Light? Concepts, Measures, and Applications of Optical Quantumness
Quantum states are ultimately responsible for numerous counterintuitive phenomena that defy classical intuition.Entanglement-enhanced Ramsey spectroscopy of broadband signals
The use of entanglement in sensing is often motivated by improved sensitivity arising from non-classical correlations among probes.
