A Model Context Protocol Server for Quantum Execution in Hybrid Quantum-HPC Environments
Masaki Shiraishi, Ikko Hamamura, Tatsuya Ishigaki +1
The integration of large language models (LLMs) into scientific research is accelerating the realization of autonomous ``AI Scientists.'' While recent advancements have empowered A…
Mitigating Precision Errors in Quantum Annealing via Coefficient Reduction of Embedded Hamiltonians
Kentaro Ohno, Nozomu Togawa
Quantum annealing is a quantum algorithm to solve combinatorial optimization problems. In the current quantum annealing devices, the dynamic range of the input Ising Hamiltonian, d…
Utilizing intermediate states in quantum annealing for multi-objective optimization
Keita Takahashi, Shu Tanaka
We investigate obtaining intermediate quantum states during the quantum annealing process to address the limitation of the linear weighted sum method in multi-objective optimizatio…
Single-shot conditional displacement gate between a trapped atom and traveling light
Seigo Kikura, Hayato Goto, Fumiya Hanamura +1
We propose a single-shot conditional displacement gate between a trapped atom as the control qubit and a traveling light pulse as the target oscillator, mediated by an optical cavi…
Robust quantification of spectral transitions in perturbed quantum systems
Zsolt Szabó, Stefan Gehr, Paolo Facchi +3
A quantum system subject to an external perturbation can experience leakage between uncoupled regions of its energy spectrum separated by a gap. To quantify this phenomenon, we pre…
Error bounds for the Floquet-Magnus expansion and their application to the semiclassical quantum Rabi model
Anirban Dey, Davide Lonigro, Kazuya Yuasa +1
We present a general, nonperturbative method for deriving effective Hamiltonians of arbitrary order for periodically driven systems, based on an iterated integration by parts techn…
