Optomagnonic generation of entangled travelling fields with different polarizations

Zi-Xu Lu, Huai-Bing Zhu, Xuan Zuo +1 more·Dec 11, 2025

The optomagnonic coupling between magnons and optical photons is an essential component for building remote quantum networks based on magnonics. Here we show that such a coupling, manifested as the magnon-induced Brillouin light scattering, can be ex...

Integrated Generation and Purification of Entangled Coherent States for Non-Gaussian Teleportation

Ananga Mohan Datta, William J. Munro, Nicolo Lo Piparo +1 more·Dec 11, 2025

Entangled coherent states (ECS) provide a powerful non-Gaussian resource for continuous-variable quantum communication, but their generation in scalable architectures remains challenging. We propose an integrated photonic scheme that creates high-fid...

Pinball: A Cryogenic Predecoder for Surface Code Decoding Under Circuit-Level Noise

Alexander Knapen, Guanchen Tao, Jacob Mack +5 more·Dec 10, 2025

Scaling fault tolerant quantum computers, especially cryogenic systems based on the surface code, to millions of qubits is challenging due to poorly-scaling data processing and power consumption overheads. One key hurdle is the design of real-time qu...

Quantum random number generation from the continuous variable payload for the SPOQC mission

Vinod N. Rao, Killian Murphy, Fadi Ahwal +3 more·Dec 10, 2025

The necessity of random numbers for various tasks, from simulation to cryptography, is crucial and immense. Here we demonstrate CV-QRNG using the CV payload of the SPOQC mission. The homodyne setup for QRNG uses the laser from the payload, in additio...

Device Independent Quantum Secret Sharing Using Multiparty Pseudo-telepathy Game

Santanu Majhi, Goutam Paul·Dec 10, 2025

Device-independent quantum secret sharing (DI-QSS) provides security against untrusted quantum devices. While device-independent quantum key distribution (DI-QKD) using Mermin-Peres magic square game [Zhen et al., Phys. Rev. Lett, 2023] has been prop...

Optyx: A ZX-based Python library for networked quantum architectures

Mateusz Kupper, Richie Yeung, Boldizsár Poór +3 more·Dec 10, 2025

Distributed, large-scale quantum computing will need architectures that combine matter-based qubits with photonic links, but today's software stacks target either gate-based chips or linear-optical devices in isolation. We introduce Optyx, an open-so...

Deterministic randomness extraction for quantum random number generation with partial trust

Pablo Tikas Pueyo, Tomás Fernández Martos, Gabriel Senno·Dec 9, 2025

It is a well-known fact in classical information theory that no deterministic procedure can extract close-to-ideal randomness from an arbitrary entropy source. On the other hand, if additional knowledge about the source is available -- e.g., that it ...
