Quantum and Classical Memory for Storage and Retrieval of Quantum Measurements
We study the persistent quantum and classical memory required for exact heralded storage and retrieval of quantum measurements.Toward Circuit-Aware Mutation Testing for Quantum Programs: Exact Visibility and Execution Planning
Mutation testing assesses test suites by introducing program changes and checking whether tests detect them.Quantum Evolution Kernel for Node-Attributed Graphs
We present a novel approach to embed node-attributed graphs onto neutral-atom quantum computers, and propose an application to digit recognition.Momentum-space entanglement and mutual information in Kaluza-Klein reduction
In theories with compact extra dimensions, the four-dimensional effective description is obtained by Kaluza-Klein reduction.The TEMPO network can be made independent of the system size
The time-evolving matrix product operator (TEMPO) method efficiently simulates non-Markovian open quantum system dynamics by contracting a two-dimensional tensor network representing the…Quantum Annealing for Gamma-ray Source Detection and Localization with AGILE Data
The detection and localization of gamma-ray sources via maximum-likelihood analysis is a complex parameter optimization problem.Exact decoherence dynamics of a detector coupled to vacuum fluctuations in bounded geometries
The properties of quantum vacuum are highly sensitive to the underlying spacetime geometry and boundary conditions.Quantum Fisher Information Deficit as a Geometric Signature of Strong-to-Weak Spontaneous Symmetry Breaking
Recently, strong-to-weak spontaneous symmetry breaking (SW-SSB) has been established as a framework for describing quantum phases in open systems.Certification Time for Weak-Force-Mediated Entanglement between Levitated Particles
Certifying motional entanglement generated by weak forces between levitated nanoparticles requires distinguishing entangled from separable states using finite, noisy measurement records.Generative quantum extreme learning machines
Training the circuit of a quantum generative model is hampered by barren plateaus, where gradients vanish exponentially with the number of qubits.Matrix Samplers and Quantum-Proof Extractors: Their Correspondence and Almost-Optimal Constructions
We establish an equivalence between matrix samplers and quantum-proof randomness extractors.Threshold Criteria for Bosonic and Fermionic Trimers on a Square Lattice: A Birman--Schwinger Comparison
We compare two three-particle lattice models on the square lattice at total quasimomentum zero: three identical bosons with attractive contact interactions, and a two-fermion plus one…QNETSIM for memory assisted design of satellite and hybrid quantum networks
Space-based quantum information networks require simulation tools that capture orbital dynamics, probabilistic quantum operations, and classical coordination.Quantum circuits of elastic wave equations via Schrödingerisation
We construct explicit quantum circuits for the velocity-stress formulation of elastic wave equations in homogeneous media using Schrödingerisation.HTM: A Hybrid Classical-Quantum Computation Model
Classical and quantum computers have achieved collaborative computation and completed applications across numerous fields.Deployed entanglement-based BBM92 quantum key distribution using frequency-converted photons emitted by a quantum dot
Establishing secure communication is an important requirement in existing and future networks.Experimental evidence for quantum Brownian motion in electron-metal decoherence
Feynman once remarked that the double-slit experiment has in its heart the only mystery of quantum mechanics.Prepare-and-measure quantum key distribution from a bound on information leakage
Every quantum key distribution (QKD) protocol must limit the information available outside the users' laboratories.Security Analysis of Ekert-type QKD Protocol Coming Under Cloning Attacks
We analyze the security of an Ekert type bipartite key distribution protocol coming under cloning attacks by an untrusted observer.Measurement incompatibility and noiseless quantum codes
We construct a rank-one minimal informationally complete measurement (MIC) with an invertible dual operator and prove that, for arbitrary finite input and output dimensions, a channel universally…
