High-fidelity two-qubit gates are achieved with heavy-fluxonium qubits, circuits that break many conventional superconducting circuit paradigms, bringing more diversity for quantum applications.

Quantum algorithms and quantum machine learning could assist high-energy physics, ranging from studying neutrino oscillations to reconstructing particle trajectories in colliders.

The most exciting cutting-edge research submitted from now through December 2024 is eligible for our final selection.

A novel scattering-mitigation scheme, using only an integrating sphere, is experimentally demonstrated to recover nearly 50% of mutual information in a quantum correlated two-mode squeezed state of light, despite a photon loss exceeding 85% in one of the modes.

A 25-qubit quantum processor architecture reduces the stray signals that can cause errors and is suitable for scaling up.

Low crosstalk levels are achieved in a superconducting quantum processor, indicating the potential of scaling up to larger numbers of qubits.

A new dressed state-based method for imaging ultracold atoms achieves subwavelength resolution and reveals the complementary capabilities of two opposite imaging strength regimes to spatially resolve nanoscale quantum states.

Numerical studies suggest that quantum optimization may provide a polynomial speedup over the best classical solvers for constraint satisfaction problems.

Higher-frequency superconducting qubits with increased thermal resilience are produced, allowing for scaling up of quantum processors with high heat dissipation budgets.

Autonomous stabilization of remote entanglement is achieved experimentally with a pair of noninteracting superconducting qubits connected by an open waveguide.

A new protocol enables the generation of arbitrary symmetric entangled states using only global single-qubit rotations in a torn Hilbert space, offering applications in variational quantum optimization with existing technology.

The policy requires authors to explain where research data can be found starting Sept. 4.
