High-Accuracy Propagation-Assisted Local Decoding for Fast Transversal Clifford Circuits
We benchmark the Iterative Redecode Scheme (IRS) on fast transversal Clifford circuits, achieving high-accuracy correlated decoding using local memory-style detectors and decoders.Correlated decoding loses the surface code's effective distance below threshold
Correlated decoding improves matching and clustering surface-code decoders by reweighting one decoding subgraph conditioned on the other's correction.Fast Hubbard-Thouless Pumping with Local Counterdiabatic Driving
Counterdiabatic (CD) driving suppresses the excitations of fast protocols by adding an auxiliary Hamiltonian, but in many-body and topological systems the exact CD term is generally non-local and…Supervised Learning with Quantum Hamiltonian Embeddings
Machine learning is widely regarded as a promising application in which quantum computing could offer a computational advantage.Quantum algorithms for optimal control: large-scale finite-horizon linear-quadratic regulation
We develop quantum algorithms for optimal control over a prescribed finite time interval (finite horizon), focusing on continuous-time linear-quadratic regulation (LQR).Boundary-Sensitive Quantum Order on Non-Amenable Lattices
We show that quantum systems on non-amenable lattices, whose boundaries constitute an extensive fraction of the system, host novel forms of bulk ordering with no Euclidean counterpart.Parallel Omnidirectional Atom Rearrangement with Dynamic Holograms
The ability to assemble and reconfigure individual atoms is central to performing quantum science using optical tweezer arrays.Nambu-Goldstone Bosons and Quantum Fisher Information
The quantum Fisher matrix and geometric tensor are powerful tools for quantifying the nature of quantum systems.Spectral signatures of hidden order and hidden quantum critical points
Hidden-order phases elude the conventional Ginzburg-Landau framework: although they spontaneously break symmetry, their order remains invisible to standard local two-point correlators.Polynomial-Time Classical Simulation of BosonSampling under Any Constant-Fraction Photon Loss
Understanding how photon loss changes the classical complexity of BosonSampling is central to assessing the robustness of near-term photonic quantum advantage.Cavity models of non-Abelian gauge theories
In quantum optics and related fields, cavity quantum electrodynamics provides a powerful framework for modeling the low-energy properties of bound charges coupled to electromagnetic fields, using a…Rényi multi-entropy of graph states and the $n -> 1$ limit
Rényi multi-entropy extends the Rényi entropy to pure states of more than two parties.A group theoretic calculation of multi-invariants of some stabilizer states
We study multi-invariants---a multi-partite generalization of Renyi entropies---of simple stabilizer states, for an arbitrary replica symmetry group.Active isolation of transmon readout with a tunable inductive bridge
Scalable superconducting quantum computation requires fast, high-fidelity readout.Allight: A Perfect Photon Collector
Collecting photons from quantum emitters remains a key limitation in light-matter interaction because conventional lenses collect light only from one direction.The next phase of quantum energy science: from mechanisms to applications
A growing research community spanning quantum batteries, molecular and excitonic energy transport, polaritonics, quantum materials and nuclear control has begun to describe its work in terms of…Quantum Fluctuations and Wigner Dynamics of a Carbon Nanotube Oscillator Driven by an Atomic Force Microscope
Suspended carbon nanotubes provide a useful platform for studying controlled nanomechanical motion in regimes where environmental fluctuations, memory effects, and quantum coherence can all…Comparative Optical Spectroscopy of Er$^{3+}$, Tm$^{3+}$, and Eu$^{3+}$ Molecular Complexes at Cryogenic Temperature
Rare-earth molecular complexes are attracting increasing interest for quantum information applications because of their structural flexibility and chemical tunability.Controlling Optical Quantum Interference with Plasmonic Metasurfaces
The ability to efficiently control optical quantum interference by the same device is a challenging task that promises to enable key operations in quantum information processing.Optimal four-copy detection of the three-tangle and its fault-tolerant cost
The three-tangle, $τ_3$, is a measure of genuine tripartite entanglement that distinguishes GHZ-type from W-type entanglement in pure three-qubit states.
