Realization of an all-optical effective negative-mass oscillator for coherent quantum noise cancellation
Nived Johny, Jonas Junker, Bernd Schulte +3 more·Nov 11, 2025
We report the realization of an all-optical, tabletop effective-negative-mass oscillator (ENMO) scheme capable of canceling quantum noise when cascaded with an opto-mechanical sensor susceptible to (quantum) radiation pressure noise. Our coherent qua...
Stabilization of Time-Varying Perturbed Quantum Systems via Reduced Filters
Weichao Liang, Daoyi Dong·Nov 11, 2025
In practical applications, quantum systems are inevitably subject to significant uncertainties, including unknown initial states, imprecise physical parameters, and unmodeled environmental noise, all of which pose major challenges to robust quantum f...
Enhancing Remote Magnon-Magnon Entanglement with Quantum Interference
Yuan Gong, Yan-Xue Cheng, Wei Xiong +1 more·Nov 11, 2025
Cavity magnonics, owing to its strong magnon-photon coupling and excellent tunability, has attracted significant interest in quantum information science. However, achieving strong and robust macroscopic entanglement remains a long-standing challenge ...
Sufficient conditions for hardness of lossy Gaussian boson sampling
Byeongseon Go, Changhun Oh, Hyunseok Jeong·Nov 11, 2025
Gaussian boson sampling (GBS) is a prominent candidate for the experimental demonstration of quantum advantage. However, while the current implementations of GBS are unavoidably subject to noise, the robustness of the classical intractability of GBS ...
New XOR & XNOR Operations in Instantaneous Noise-Based Logic
Nasir Kenarangui, Arthur Powalka, Laszlo B. Kish·Nov 11, 2025
Instantaneous Noise-Based Logic (INBL) presents a classical noise-based computing framework as an alternative to quantum computation, though some logic gates remain unimplemented for achieving universality over superpositions. INBL encodes M noise-...
Optimal phase estimation in the presence of correlated dephasing
Srijon Ghosh, Arkadiusz Kobus, Stanisław Kurdziałek +1 more·Nov 10, 2025
We investigate optimal metrological protocols for phase estimation in the presence of correlated dephasing noise, including spin-squeezed states sensing strategies as well as parallel and adaptive protocols optimized using tensor-network based numeri...
Recent Advances on Nonadiabatic Geometric Quantum Computation
Zheng-Yuan Xue, Cheng-Yun Ding·Nov 10, 2025
The geometric phase stands as a foundational concept in quantum physics, revealing deep connections between geometric structures and quantum dynamical evolution. Unlike dynamical phases, geometric phases exhibit intrinsic resilience to certain types ...
Sample-efficient quantum error mitigation via classical learning surrogates
Wei-You Liao, Ge Yan, Yujin Song +5 more·Nov 10, 2025
The pursuit of practical quantum utility on near-term quantum processors is critically challenged by their inherent noise. Quantum error mitigation (QEM) techniques are leading solutions to improve computation fidelity with relatively low qubit-overh...
Rejection of wavefront aberrations in an atomic gradiometer
Louis Pagot, Sébastien Merlet, Leonid A Sidorenkov +1 more·Nov 10, 2025
One of the main residual limitations of inertial sensors based on atom interferometry stems from laser beam distortions, which cause parasitic phase shifts and non-homogeneous matter-light couplings. Here we present numerical simulations, accompanied...
Dense packing of the surface code: code deformation procedures and hook-error-avoiding gate scheduling
Kohei Fujiu, Shota Nagayama, Shin Nishio +2 more·Nov 10, 2025
The surface code is one of the leading quantum error correction codes for realizing large-scale fault-tolerant quantum computing (FTQC). One major challenge in realizing surface-code-based FTQC is the extremely large number of qubits required. To mit...

We introduce a tunable framework for generalized quantum state discrimination (GSD) and apply it to quantum key distribution (QKD) through a protocol we call phiQKD. Building upon the two-state B92 protocol, phiQKD replaces the traditional unambiguou...
