The development of quantum processors for practical fluid flow problems is a promising yet distant goal. Recent advances in quantum linear solvers have highlighted their potential for classical fluid dynamics. In this study, we evaluate the Harrow–Ha...
Even-Balanced States Excitation in Two-Qubits System
Y. Koral, Shilo Avraham, M. Periyasamy +3 more·Sep 16, 2024
An essential step in building a quantum computer system is combining two qubits. Previous theoretical analyses of this element have been based primarily on the short schematic matrix approaches. In the present work we extend the investigation to the ...
Multi-Objective Quantum Power System Redispatch
Loong Kuan Lee, Johannes Knaute, Florian Gerhardt +4 more·Sep 15, 2024
The rising energy production costs and the increasing reliance on volatile renewable sources have driven the need for more efficient power system redispatch strategies. In this work, we re-interpret the redispatch problem as a multi-objective combina...
Comparison of Atom Detection Algorithms for Neutral Atom Quantum Computing
Jonas Winklmann, Andrea Alberti, Martin Schulz·Sep 15, 2024
In neutral atom quantum computers, readout and preparation of the atomic qubits are usually based on fluorescence imaging and subsequent analysis of the acquired image. For each atom site, the brightness or some comparable metric is estimated and use...
Using Optimal Control to Guide Neural-Network Interpolation of Continuously-Parameterized Gates
Bikrant Bhattacharyya, Fredy An, Dominik Kozbiel +2 more·Sep 15, 2024
Control synthesis for continuously-parameterized families of quantum gates can enable critical advantages for mid-sized quantum computing applications in advance of fault-tolerance. We combine quantum optimal control with physics-informed machine lea...
Quantum data encoding as a distinct abstraction layer in the design of quantum circuits
