Noise-resilient nanophotonic gyroscope with sub-prad phase resolution
Yu Tao, Xinhang Li, Jingzheng Huang +5 more·Apr 1, 2026
Optical gyroscopes based on the Sagnac effect are the cornerstone of precision orientation and navigation. However, their bulky form factors prevent deployment in emerging mobile and autonomous systems. On nanophotonic platforms, the Sagnac signal pl...
Structured detection microscopy
Larnii Booth, Kyle Clunies-Ross, Rumelo Amor +4 more·Apr 1, 2026
Super-resolution microscopy is crucial for imaging sub-wavelength biological structures. However, most techniques rely on nonlinear saturation or stochastic switching of emitters, limiting imaging speed and increasing phototoxicity. Here, we achieve ...
Hybrid Classical--Quantum Optimization of Wireless Routing Using QAOA and Quantum Walks
Eric Howard, Hardique Dasore, Hom Nath Dhungana +4 more·Apr 1, 2026
Routing in wireless communication networks is shaped by mobility, interference, congestion, and competing service requirements, making route selection a high-dimensional constrained optimization problem rather than a simple shortest-path task. This p...
Conclusive Identification Via Noisy Classical Channel: Superactivation and Quantum Advantage
Anushko Chattopadhyay, Ambuj, Rakesh Das +4 more·Mar 31, 2026
We introduce conclusive identification task for classical channels: a receiver identifies transmitted inputs without error when possible, and responds inconclusively when outputs are ambiguous. For a symmetric not-fully-corrupted channel $N : X \to X...
Noise Inference by Recycling Test Rounds in Verification Protocols
Amit Saha, Harold Ollivier·Mar 31, 2026
Interactive verification protocols for quantum computations allow to build trust between a client and a service provider, ensuring the former that the instructed computation was carried out faithfully. They come in two variants, one without quantum c...
Strong converse bounds on the classical identification capacity of the qubit depolarizing channel
Liuhang Ye, Bjarne Bergh, Nilanjana Datta·Mar 31, 2026
A strong converse bound for the classical identification capacity of a quantum channel is an upper bound on the asymptotic identification rate of classical messages sent through the channel, such that, above this rate, the probability of an identific...
Four Generations of Quantum Biomedical Sensors
Xin Jin, Priyam Srivastava, Ronghe Wang +7 more·Mar 31, 2026
Quantum sensing technologies offer transformative potential for ultra-sensitive biomedical sensing, yet their clinical translation remains constrained by classical noise limits and a reliance on macroscopic ensembles. We propose a unifying generation...
Optimal Control of Spin Squeezing in 2D Finite-Range Interacting Systems
Ang Li, Ling-Na Wu, Li You·Mar 31, 2026
Spin squeezing serves as both a fundamental witness of quantum entanglement and a critical resource for quantum-enhanced metrology. While generating substantial spin squeezing in finite-range interacting systems remains challenging, such capability i...

N. R. Cooper, Y. Yang, C. Weitenberg·Mar 31, 2026
Quantum gas microscopes offer unprecedented insights into quantum many-body states of cold atomic gases. Here we introduce concrete protocols for extending quantum gas microscopes to measure in phase space, by mapping momentum onto auxiliary degrees ...
Logical-to-Physical Compilation for Reducing Depth in Distributed Quantum Systems
Folkert de Ronde, Stephan Wong, Sebastian Feld·Mar 31, 2026
Quantum computing is expected to become a foundational technology for solving problems that exceed the capabilities of classical systems. As quantum algorithms and hardware technologies continue to advance, the need for scalable architectures becomes...
Non-perturbative CPMG scaling and qutrit-driven breakdown under compiled superconducting-qubit control: a single-qubit study
Jun Ye·Mar 31, 2026
Decoherence in superconducting qubits emerges from the interplay of multilevel dynamics and structured environmental noise, yet perturbative models cannot capture all resulting signatures. Here, EmuPlat couples instruction-set-architecture-level wave...
Testing classical-quantum gravity with geodesic deviation
Tomoya Hirotani, Akira Matsumura·Mar 31, 2026
A novel semiclassical gravity model proposed by Oppenheim et al., that consistently describes interactions between quantum systems and a classical gravitational field, has recently attracted considerable attention. However, the limitations and phenom...
Pointwise and dynamic programming control synthesis for finite-level open quantum memory systems
Igor G. Vladimirov, Ian R. Petersen, Guodong Shi·Mar 31, 2026
This paper is concerned with finite-level quantum memory systems for retaining initial dynamic variables in the presence of external quantum noise. The system variables have an algebraic structure, similar to that of the Pauli matrices, and their Hei...
Quantum Fisher information in many-photon states from shift current shot noise
Evgenii Barts, Takahiro Morimoto, Naoto Nagaosa·Mar 31, 2026
Quantum Fisher information (QFI) sets the ultimate precision of optical phase measurements and reveals multiphoton entanglement, but it is not accessible with conventional photodetection. We theoretically predict that a photodetector utilizing the sh...
High-efficiency and noise-immune quantum battery

Nowadays, quantum batteries (QBs) have been designed to outperform their classical counterparts by leveraging quantum advantages. For instance, the charging power greatly benefits from the entanglement generation of a collective charging scheme (e.g....
Quantum Optical Neuron for Image Classification via Multiphoton Interference
Giorgio Minati, Simone Roncallo, Simone Scrofana +6 more·Mar 30, 2026

Color code off-the-hook: avoiding hook errors with a single auxiliary per plaquette
Gilad Kishony, Austin Fowler·Mar 30, 2026
Syndrome extraction in the planar color code is complicated by high weight stabilizers and hook errors that can reduce the circuit-level distance. With a single auxiliary qubit per plaquette, any spatially uniform circuit halves the circuit-level dis...
Open-System Adiabatic Quantum Search under Dephasing
Afaf El Kalai, Peter J. Eder, Christian B. Mendl·Mar 30, 2026
Adiabatic quantum algorithms must evolve slowly enough to suppress non-adiabatic transitions while remaining fast enough to be practical. In open systems, this trade-off is reshaped by decoherence. For Hamiltonians subject to dephasing Lindbladians, ...

A. Sultanov, E. Mutsenik, L. Kaczmarek +4 more·Mar 30, 2026
The emission of photon from an individual atom encodes the phase of its initialized quantum state. Using single-shot heterodyne detection, we measure the phase distribution of the emission from a superconducting transmon qubit in an open waveguide co...
Geometric Foundations of Stochastic and Quantum Dynamics
