Interactions Protect Periodically Driven Time Crystals Against Dephasing but Destabilise Multipolar-Driven Order
We show that stronger interactions protect periodically driven time-crystal order against dephasing but destabilise order under random multipolar drives, and that coordination matters beyond the…Effective atom-dimer bands of three-body lattice systems at strong coupling: exact critical mass ratios and a statistics-quasimomentum duality
We study three particles on the square lattice with contact interactions of infinite strength, for all total quasimomenta, for three statistics: three identical bosons, two identical fermions plus a…Simultaneously Query-Optimal Quantum Linear-System Algorithm
Quantum linear-system algorithms access the coefficient matrix through a block-encoding oracle $U_A$ and the right-hand side through a state-preparation oracle $U_b$.On Embedding Design in Quantum Physics-Informed Neural Networks
Quantum physics-informed neural networks (QPINNs) solve partial differential equations (PDEs) by training parameterized quantum circuits against physics-based residuals, yet the role of the…Placement-driven reversal of preferred spin alignment in monolayer hBN vacancy pairs
The negatively charged boron vacancy is an optically addressable spin centre in hexagonal boron nitride (hBN), but bringing two vacancies together introduces electronic interactions absent from the…Autonomous phase discovery
Understanding quantum phases of matter has long relied on physicists' intuition and mathematical tools such as symmetry and topology.Quantum data processing equality
The quantum data processing inequality asserts that quantum relative entropy is monotonically non-increasing under quantum channels.Dynamic Sculpting of Photon Statistics in a Raman-Coupled Cavity QED System
Controlling photon statistics is pivotal to many applications in classical and quantum photonics.Nonlinear engineering of Hong-Ou-Mandel interference with structured light
A pair of photons entering a Hong-Ou-Mandel interferometer will bunch or anti-bunch depending on the symmetry of their state in the measured degree of freedom, resulting in constructive or…Quantum-Computing Self-Consistent Kohn-Sham DFT: Plane-Wave-Orthonormalized Orbitals with a Dual-Basis Quantum Eigensolver
We present a first-quantization, all-electron, full-potential Kohn-Sham density functional theory method for quantum computers, based on a classically optimized quantum-circuit eigensolver for the…Hardness of Approximating Quantum Code Distance Beyond $\sqrt{N}$
We study the computational complexity of approximating the minimum distance of a stabilizer code.Swapping Quantum Annealing Errors into a Cavity
Quantum annealing is a promising form of quantum computation, but it slows down at a small energy gap $Δ$ during the anneal, and the errors it makes there remain undetected.QBX: A Compiler for 2-local Qubit Hamiltonian Simulation on Quantum Chiplets
2-local qubit Hamiltonian simulation, a fundamental task in quantum computing, is widely applied in various applications.Particles, Localization and "Collapse"
Hegerfeldt's theorem shows that the localization of a particle (or field) is not possible under very general assumptions of quantum mechanics and special relativity.Counterdiabatic quasi-Floquet control for the generation of entangled BICs using giant atoms
Bound states in the continuum (BICs) provide a mechanism for preserving entanglement in waveguide quantum electrodynamics.Inverse-Designed Nanobeam Cavities for High-Cooperativity Spin-Photon Interfaces in Silicon
Telecom-band spin defects in silicon offer a compelling platform for integrated quantum networks by combining scalable silicon photonics with spin-based quantum memories and multiqubit registers.Quantum undular bores, rainbows, and event horizons in superfluid dam breaks
The sudden removal of a potential barrier from a Bose-Einstein condensate (BEC) gives rise to a quantum version of a hydrodynamic dam break and leads to rich wave dynamics that have similarities to…Contour-integral and Fourier transform based multivariable quantum eigenvalue transformation for commuting matrices
We study the problem of implementing multivariable matrix-valued functions on a quantum computer and propose two quantum algorithms for multivariable matrix eigenvalue transformations acting on…Symmetry-permuting entanglers for non-invertible symmetry-protected topological phases
1+1D symmetry-protected topological (SPT) phases with invertible symmetry can be characterized by the symmetric entanglers: globally symmetric finite-depth local unitary circuits that generate…Conserved and relaxing modes enable polynomial-success coherent Carleman lattice Boltzmann evolution
Carleman linearization represents nonlinear lattice Boltzmann collision dynamics in a form amenable to quantum block encoding, but low postselection probabilities in existing population-space…
