Large deviations, gradient flows and fluctuating hydrodynamics for fractional diffusion
Julien Barre, Hiroshi Horii
This work is a step towards a general understanding of fluctuations for systems of particles described at large scale by fractional diffusion. First, we derive formally a Large Dev…
Examining QRMI as a Unified Interface for Quantum-HPC Integration
Thomas Badts, Tim Boyle, Claudio Carvalho +25
The efficient and scalable integration of quantum resources into high-performance computing (HPC) environments requires standardized mechanisms for resource management, scheduling,…
Diffusion stabilises time-periodic solutions in conservation laws coupled to a relaxation oscillator
Julien Barré, Nils Berglund, Hiroshi Horii
We study a viscous one-dimensional conservation law, coupled to a fast ordinary differential equation. For a vanishing viscosity, the system has an infinite-dimensional family of t…
Crossing the 12,000-atom barrier with heterogeneous quantum-classical supercomputing: quantum chemistry of protein-ligand complexes
Kenneth M. Merz, Akhil Shajan, Danil Kaliakin +21
We develop a workflow decomposing a molecule into fragments via quantum embedding and simulating them with a heterogeneous quantum-classical (HQC) method. We sample fragment electr…
Reference Architecture of a Quantum-Centric Supercomputer
Seetharami Seelam, Jerry M. Chow, Antonio Córcoles +10
Quantum computers have demonstrated utility in simulating quantum systems beyond brute-force classical approaches. As the community builds on these demonstrations to explore using…
GPU-Accelerated Selected Basis Diagonalization with Thrust for SQD-based Algorithms
Jun Doi, Tomonori Shirakawa, Yukio Kawashima +2
Selected Basis Diagonalization (SBD) plays a central role in Sample-based Quantum Diagonalization (SQD), where iterative diagonalization of the Hamiltonian in selected configuratio…
Observability Architecture for Quantum-Centric Supercomputing Workflows
Naoki Kanazawa, Yuto Morohoshi, Hitomi Takahashi +3
Quantum-centric supercomputing (QCSC) workflows often involve hybrid classical-quantum algorithms that are inherently probabilistic and executed on remote quantum hardware, making…
Closed-loop calculations of electronic structure on a quantum processor and a classical supercomputer at full scale
Tomonori Shirakawa, Javier Robledo-Moreno, Toshinari Itoko +18
Quantum computers must operate in concert with classical computers to deliver on the promise of quantum advantage for practical problems. To achieve that, it is important to unders…
Optimal Condition for Initialization Variance in Deep Neural Networks: An SGD Dynamics Perspective
Hiroshi Horii, Sothea Has
Stochastic gradient descent (SGD), one of the most fundamental optimization algorithms in machine learning (ML), can be recast through a continuous-time approximation as a Fokker-P…
Design and architecture of the IBM Quantum Engine Compiler
Michael B. Healy, Reza Jokar, Soolu Thomas +7
In this work, we describe the design and architecture of the open-source Quantum Engine Compiler (qe-compiler) currently used in production for IBM Quantum systems. The qe-compiler…
