Strongly driven cavity quantum electrodynamical-optomechanical hybrid system
Xuxin Wang, Jiahe Pan, Tobias J. Kippenberg +1 more·Dec 8, 2025
Hybrid quantum systems harness the distinct advantages of different physical platforms, yet their integration is not always trivial due to potential incompatibilities in operational principles. Here, we theoretically propose and demonstrate a scheme ...
A Framework for Data Valuation and Monetisation
Eduardo Vyhmeister, Bastien Pietropaoli, UdoBub +2 more·Dec 8, 2025
As organisations increasingly recognise data as a strategic resource, they face the challenge of translating informational assets into measurable business value. Existing valuation approaches remain fragmented, often separating economic, governance, ...
Site-controlled quantum dot arrays edge-coupled to integrated silicon nitride waveguides and devices
John O'Hara, Nicola Maraviglia, Mack Johnson +7 more·Dec 8, 2025
The scalability of quantum photonic integrated circuits opens the path towards large-scale quantum computing and communication. To date, this scalability has been limited by the stochastic nature of the quantum light sources. Moreover, hybrid integra...
Fair Benchmarking of Optimisation Applications
Frank Phillipson·Dec 8, 2025
Quantum optimisation is emerging as a promising approach alongside classical heuristics and specialised hardware, yet its performance is often difficult to assess fairly. Traditional benchmarking methods, rooted in digital complexity theory, do not d...
33 Gbit/s source-device-independent quantum random number generator based on heterodyne detection with real-time FPGA-integrated extraction
Marius Cizauskas, Hamid Tebyanian, Mark Fox +3 more·Dec 8, 2025
We present a high-speed continuous-variable quantum random number generator (QRNG) based on heterodyne detection of vacuum fluctuations. The scheme follows a source-device-independent (SDI) security model in which the entropy originates from quantum ...
Revisiting Quantum Supremacy: Simulating Sycamore-Class Circuits Using Hybrid CPU/GPU HPC Workloads
Bob Wold, Venkateswaran Kasirajan·Dec 8, 2025
We present a framework for effectively simulating the execution of quantum circuits originally designed to demonstrate quantum supremacy using accessible high-performance computing (HPC) infrastructure. Building on prior CPU-only approaches, our pipe...
A versatile coherent Ising computing platform
Hai Wei, Chengjun Ai, Putuo Guo +12 more·Dec 8, 2025
Coherent Ising Machines (CIMs) have emerged as a hybrid form of quantum computing devices designed to solve NP-complete problems, offering an exciting opportunity for discovering optimal solutions. Despite challenges such as susceptibility to noise-i...
Digital-Analog-Digital Quantum Supremacy
Daniel Lidar·Dec 8, 2025
Quantum supremacy has been explored extensively in gate-model settings. Here, we introduce a quantum-supremacy framework for a hybrid digital-analog-digital quantum computing (DADQC) model. We consider a device that applies an initial layer of single...
Suppressing Fast Dipolar Noise in Solid-State Spin Qubits
Jaime García Oliván, Ainitze Biteri-Uribarren, Oliver T. Whaites +1 more·Dec 7, 2025
Spin qubit coherence is a fundamental resource for the realization of quantum technologies. For solid-state platforms, spin decoherence is dominated by the magneto-active environment in the lattice, limiting their applicability. While standard dynami...
Laser-written reconfigurable photonic integrated circuit directly coupled to a single-photon avalanche diode array
Giulio Gualandi, Simone Atzeni, Marco Gardina +8 more·Dec 6, 2025
To date, most integrated quantum photonics experiments rely on single-photon detectors operating at cryogenic temperatures coupled to photonic integrated circuits (PICs) through single-mode optical fibers. This approach presents significant challenge...
Solving larger Travelling Salesman Problem networks with a penalty-free Variational Quantum Algorithm
Daniel Goldsmith, Xing Liang, Dimitrios Makris +1 more·Dec 6, 2025
The Travelling Salesman Problem (TSP) is a well-known NP-Hard combinatorial optimisation problem, with industrial use cases such as last-mile delivery. Although TSP has been studied extensively on quantum computers, it is rare to find quantum solutio...

Jaeyong Hwang, Tianrui Xu, Sean R. Muleady +5 more·Dec 6, 2025
We propose the use of motional states of two interacting atoms trapped in a potential stroboscopically engineered by an optical tweezer as a means to implement a qubit-oscillator system, in analogy to those implemented in circuit quantum electrodynam...
Quantum Interior Point Methods: A Review of Developments and An Optimally Scaling Framework
Mohammadhossein Mohammadisiahroudi, Zeguan Wu, Pouya Sampourmahani +2 more·Dec 6, 2025
The growing demand for solving large-scale, data-intensive linear and conic optimization problems, particularly in applications such as artificial intelligence and machine learning, has highlighted the limitations of classical interior point methods ...

Farzad Molani, Art E. Cho·Dec 5, 2025
Accurately predicting protein-ligand binding free energies (BFEs) remains a central challenge in drug discovery, particularly because the most reliable methods, such as free energy perturbation (FEP), are computationally intensive and difficult to sc...
