Adaptive decoding of quantum LDPC codes through decoder disagreement
Maida Wang, Peter V. Coveney
Accurate decoding of quantum low-density parity-check (qLDPC) codes often relies on expensive post-processing search, although decoding difficulty varies strongly between syndromes…
Reduced Subgrid-Scale Terms for Turbulence Simulations with the Lattice Boltzmann Method
Rik Hoekstra, Xiao Xue, Peter V. Coveney +1
Turbulent flows span a wide range of scales, making direct numerical simulation (DNS) prohibitively expensive at high Reynolds numbers. Large eddy simulation (LES) offers a pragmat…
Parallel and Distributed Fermionic Simulation via Dynamic Encoding
Michael Williams de la Bastida, Peter V. Coveney
We demonstrate a simple and efficient method to parallelize and distribute Trotterized Hamiltonian simulation of fermionic systems across multiple QPUs. Using combinatorial coverin…
TNASS: Tensor Network Active Space Selection with the Entanglement Feature
Angus Mingare, Isabelle Heuzé, Peter V. Coveney
The quality of multi-scale modelling techniques in molecular electronic structure calculations, such as embedding and subspace methods, relies upon the chosen active space. The aut…
Quantum Statistical Memory Advantage Reveals Predictive Structure in Chaotic Invariant Measures
Maida Wang, Xiao Xue, Minh Chung +1
Long-horizon prediction of a chaotic system is governed by fidelity to its invariant measure, and which parts of that measure a learned predictor needs is a physical question not k…
Explainable quantum-compressed machine learning for complex fluid flows
Xiao Xue, Maida Wang, Mingyang Gao +2
Machine-learning surrogates of physical systems face a paradox: explainable models facing the challenge of expressivity to capture complex nonlinear flows, whereas expressive deep…
Quantum-Accelerated Self-Consistent Field: A Hybrid Algorithm
Alexis Ralli, Tim Weaving, Thomas M. Bickley +2
We present the Grover adaptive search self-consistent field (GAS-SCF) algorithm. GAS-SCF leverages quantum arithmetic to construct an efficient oracle that marks target states (Foc…
Irreversibility, equilibrium and measurement in quantum mechanics
Christopher J. N. Coveney, Peter V. Coveney
Quantum mechanics is widely recognised as being incomplete. It is not consistent with the second law of thermodynamics and does not provide a scientifically credible physical accou…
On the Smallness of the Large Language Models Scaling Exponents
Sauro Succi, Peter V. Coveney, Alex Hansen
We discuss reasons why the scaling exponents of current Large Language Models (LLMs) applications are indicating an unsustainable regime in terms of energy resources. We further sh…
Practical Log-Depth Quantum State Preparation and Circuit Verification via Tree Tensor Network Compilation
Angus Mingare, Peter V. Coveney
Matrix product states provide efficient classical descriptions of quantum systems that may be useful as reference states for quantum algorithms such as quantum phase estimation and…
Uni-Flow: a unified autoregressive-diffusion model for complex multiscale flows
Xiao Xue, Tianyue Yang, Mingyang Gao +7
Spatiotemporal flows govern diverse phenomena across physics, biology, and engineering, yet modelling their multiscale dynamics remains a central challenge. Despite major advances…
