Three-axis Active Magnetic Compensation with Spatial Feedforward Matrix Decoupling and Hysteresis PI Regulation for Suppressing Zeeman Decoherence of Cold Atom Quantum Memories
Cold-atom quantum memories require a near-zero magnetic environment (residual field <1 microtesla) to mitigate Zeeman decoherence.Superconducting circuits host two-level systems with lifetimes exceeding one second
Understanding the microscopic environment of superconducting qubits is a central challenge for quantum technologies.One generation of the Standard Model as a quantum error-correcting code
Together with a right-handed neutrino, the fermions of one generation of the Standard Model are labelled by five bits, a combinatorial structure tied to anomaly cancellation.Hybrid Quantum-Classical Optimization for Emergency-Priority Traffic Signal Control
Emergency-priority traffic signal control requires reducing emergency-vehicle delay while limiting disruption to ordinary traffic.Selected Stabilizer Subspaces for Compact Many-Body Wave Functions
Selected configuration interaction (SCI) obtains accurate many-body solutions by variationally diagonalising the Hamiltonian in a sparse, iteratively selected set of configurations, but can lose…Looking Beyond Visibility: Resolving the Temporal Structure of Continuous-Wave Four-Photon Hong-Ou-Mandel Interference
Hong-Ou-Mandel interference underpins many photonic quantum information protocols and is commonly characterized by a single visibility parameter.Opinion bubbles in the quantum Buridan's ass problem
The quantum Buridan's ass problem concerns a network of interconnected nodes in which transitions between the nodes are governed by the laws of quantum mechanics.Synergistic charging of a quantum battery via Dzyaloshinskii-Moriya interaction and non-Markovian noise
Protecting quantum batteries from environmental noise remains a challenge.ZZ-Free bSWAP Gates under Strong Driving in Far-Detuned Fixed-Frequency Transmons
Far-detuned frequency allocations in fixed-frequency superconducting processors mitigate spectral crowding but constrain cross-resonance interactions at practical drive amplitudes.Jianmu-Q: Bridging Quantum Field Theory and Quantum Hardware with AI Agents
Quantum computing offers a promising approach to non-perturbative simulations of quantum field theories, particularly for real-time dynamics and systems affected by the sign problem.A complete classification of perfect state transfer in Grover walks on abelian Cayley graphs
We completely classify connected Cayley graphs over finite abelian groups that exhibit perfect state transfer in Grover walks.Quantum control of solid state qubits via Reinforcement Learning
The use of reinforcement learning (RL) in the design of quantum control strategies for pulse level control of NISQ era quantum devices is attracting growing interest.Thermal activation of photon catalysis in difference-intensity Mach-Zehnder interferometry with squeezed thermal light
Realistic non-Gaussian operations, which can be implemented by mixing a nonclassical Gaussian state with a Fock state at a beam splitter and then heralding on a photon-number-resolving detector, are…Loss-independent time-delay estimation via Hong-Ou-Mandel photon bunching detection
In this work we study the application of two-photon correlated quantum states for high-precision time estimation.Energetic channels in finite many-body quantum charging
We examine how a finite many-body system can function as an effective charger for a single-qubit quantum battery, using the Lipkin-Meshkov-Glick model as a paradigmatic setting.Generalized $m$-body mean-field projections for classical simulation of $d$-dimensional Heisenberg-picture dynamics
Classical simulation of quantum many-body dynamics is challenged by the rapid growth of operator complexity, particularly in higher dimensions where tensor-network methods become increasingly…Bubble-Sort Exchange Networks: Symmetry Selection Rules and Language-Model Distillation on Exchange-Only Spin Chains
On a chain of exchange-coupled quantum dots a Heisenberg exchange pulse of area pi is a SWAP, so the parallel bubble-sort SWAP network of superconducting chains is native to exchange-only (EO) spin…Operational Limits of Gravity-Mediated Entanglement
Tests of gravity-mediated entanglement aim to determine whether two massive objects in spatial superposition can become entangled through their mutual gravitational interaction.Patchwork: automated lattice surgery and space-time partitioning for real-time decoding
We introduce patchwork, a lattice-surgery compiler for arbitrary multi-qubit Pauli measurements on a prescribed narrow-corridor two-dimensional surface-code layout.Putting a Temperature on Electron Correlation
It is common wisdom that a better understanding of how to quantify electron correlation should lead to more efficient treatments of the correlation problem.
