Objective Reduction of the Wave Function Demonstrated on Superconducting Quantum Compute
James Tagg, William Reid·Apr 3, 2025
We describe an experiment using superconducting transmon qubits that demonstrates wavefunction collapse consistent with Orchestrated Objective Reduction (Orch-OR) - the theory of consciousness proposed by Sir Roger Penrose and Stuart Hameroff. The ex...
An Overview of Josephson Junctions Based QPUs
Omid Mohebi, Alireza Mohseni·Apr 3, 2025
Quantum processing units (QPUs) based on superconducting Josephson junctions promise significant advances in quantum computing. However, they face critical challenges. Decoherence, scalability limitations, and error correction overhead hinder practic...
A Scalable Synthesis Algorithm for Reversible Functions
Moein Sarvaghad-Moghaddam, M. S. Zamani, M. Sedighi·Apr 3, 2025
Reversible computation is an emerging technology that has gained significant attention due to its critical role in quantum circuit synthesis and low-power design. This paper introduces a transformation-based method for exact synthesis of reversible c...
Simulation of Atomic Layer Deposition with a Quantum Computer
Evgeny Plekhanov, Georgia Prokopiou, Michal Krompiec +4 more·Apr 3, 2025
In this work, we present the study of an atomic layer deposition (ALD) of zirconium by means of a quantum computation on an emulator representing the features of an architecture based on qubits implemented on carbon nanotubes. ALD process control is ...
Quantum Gibbs states are locally Markovian
Chi-Fang Chen, Cambyse Rouz'e·Apr 3, 2025
The Markov property entails the conditional independence structure inherent in Gibbs distributions for general classical Hamiltonians, a feature that plays a crucial role in inference, mixing time analysis, and algorithm design. However, much less is...
State Specific Measurement Protocols for the Variational Quantum Eigensolver
Davide Bincoletto, Jakob S. Kottmann·Apr 3, 2025
A central roadblock in the realization of variational quantum eigensolvers on quantum hardware is the high overhead associated with measurement repetitions, which hampers the computation of complex problems, such as the simulation of mid- and large-s...
Direction switchable single-photon emitter using a Rydberg polariton
Chang-Yong Li, Xiao-Feng Shi, Y. Jiao +5 more·Apr 3, 2025
All-optical redirection or routing of single photons is essential for quantum networks. Although studied in various systems both in theory and experiment, the redirection of single photons with many output ports, compatible with large-scale photonic ...
HQViT: Hybrid Quantum Vision Transformer for Image Classification
Hui Zhang, Qinglin Zhao, MengChu Zhou +1 more·Apr 3, 2025
Transformer-based architectures have revolutionized the landscape of deep learning. In computer vision domain, Vision Transformer demonstrates remarkable performance on par with or even surpassing that of convolutional neural networks. However, the q...
Quantum algorithms through graph composition
Arjan Cornelissen·Apr 2, 2025
In this work, we unify several quantum algorithmic frameworks for boolean functions that are based on the quantum adversary bound. First, we show that the $st$-connectivity framework subsumes the (adaptive/extended) learning graph framework, and the ...
Catalytic Activation of Bell Nonlocality
Jessica Bavaresco, Nicolas Brunner, Antoine Girardin +2 more·Apr 2, 2025
The correlations of certain entangled states can be perfectly simulated classically via a local model. Hence such states are termed Bell local, as they cannot lead to Bell inequality violation. Here, we show that Bell nonlocality can nevertheless be ...
Fermionic Averaged Circuit Eigenvalue Sampling
Adrian Chapman, Steven T. Flammia·Apr 2, 2025
Fermionic averaged circuit eigenvalue sampling (FACES) is a protocol to simultaneously learn the averaged error rates of many fermionic linear optical (FLO) gates simultaneously and self-consistently from a suitable collection of FLO circuits. It is ...

Understanding and solving fluid dynamics equations efficiently remains a fundamental challenge in computational physics. Traditional numerical solvers and physics-informed neural networks struggle to capture the full range of frequency components in ...
Scaling of entanglement entropy and correlations in the variable-range extended Ising model
Harikrishnan K J, Debasis Sadhukhan, Amit Kumar Pal·Apr 2, 2025
We study the two-point correlation functions and the bipartite entanglement in the ground state of the exactly-solvable variable-range extended Ising model of qubits in the presence of a transverse field on a one-dimensional lattice. We introduce the...
Quantum Meets SAR: A Novel Range-Doppler Algorithm for Next-Gen Earth Observation
Khalil Al Salahat, Mohamad El Moussawi, Ali J. Ghandour·Apr 2, 2025
Synthetic Aperture Radar (SAR) plays a vital role in remote sensing due to its ability to capture high-resolution images regardless of weather conditions or daylight. However, to transform the raw SAR signals into interpretable imagery, advanced data...
Iterative Interpolation Schedules for Quantum Approximate Optimization Algorithm
Anuj Apte, Shree Hari Sureshbabu, Ruslan Shaydulin +5 more·Apr 2, 2025
Quantum Approximate Optimization Algorithm (QAOA) is a promising quantum heuristic with empirical evidence of speedup over classical state-of-the-art for some problems. QAOA uses a parameterized circuit with $p$ layers, where higher $p$ yields better...
Arbitrary gauge quantisation of light-matter theories with time-dependent constraints
Adam Stokes, Ahsan Nazir·Apr 2, 2025
We provide a general framework for the quantisation of light-matter theories with time-dependent holonomic constraints. Unless time dependence is present from the outset at the Lagrangian level, different gauges generally produce non-equivalent canon...
