Differential equation quantum solvers: engineering measurements to reduce cost
Annie E. Paine, Casper Gyurik, A. A. Gentile·Mar 28, 2025
Quantum computers have been proposed as a solution for efficiently solving non-linear differential equations (DEs), a fundamental task across diverse technological and scientific domains. However, a crucial milestone in this regard is to design proto...
Circuit cutting with classical side information
C. Piveteau, Lukas Schmitt, David Sutter·Mar 28, 2025
Circuit cutting is a technique for simulating large quantum circuits by partitioning them into smaller subcircuits, which can be executed on smaller quantum devices. The results from these subcircuits are then combined in classical post-processing to...
Quantum approximate multi-objective optimization
Ayse Kotil, Elijah Pelofske, Stephanie Riedmüller +4 more·Mar 28, 2025
The goal of multi-objective optimization is to understand optimal trade-offs between competing objective functions by finding the Pareto front, that is, the set of all Pareto-optimal solutions, where no objective can be improved without degrading ano...
Variational quantum-neural hybrid imaginary time evolution
H. Kuji, T. Nikuni, Yuta Shingu·Mar 28, 2025
Numerous methodologies have been proposed to implement imaginary time evolution (ITE) on quantum computers. Among these, variational ITE (VITE) methods for noisy intermediate-scale quantum (NISQ) computers have attracted much attention, which uses pa...
Cryogenic Magnomechanics for Thermometry Applications
Y. Huang, P. M. C Rourke, A. Peruzzi +4 more·Mar 27, 2025
Cavity magnomechanics combines strong coupling between magnons in a dielectric material and microwave cavity photons with long-lived mechanical resonances. Forming a triple resonance condition, this hybrid quantum system promises many advantages in q...
Theory-Independent Context Incompatibility: Quantification and Experimental Demonstration
Mariana Storrer, Patrick Lima, Ana C. S. Costa +2 more·Mar 27, 2025
The concept of compatibility originally emerged as a synonym for the commutativity of observables and later evolved into the notion of measurement compatibility. In any case, however, it has remained predominantly algebraic in nature, tied to the for...
Parameter estimation with one- and two-time measurements on the emission field of the boundary time crystal
Albert Cabot, Federico Carollo, Igor Lesanovsky·Mar 27, 2025
Many-body quantum systems can exhibit collective effects that enhance the sensitivity of parameter estimation protocols. An example is provided by resonantly driven two-level atoms subject to collective dissipation, which can display a transition bet...
Adiabatic quantum state preparation in integrable models
Maximilian Lutz, Lorenzo Piroli, Georgios Styliaris +1 more·Mar 27, 2025
We propose applying the adiabatic algorithm to prepare high-energy eigenstates of integrable models on a quantum computer. We first review the standard adiabatic algorithm to prepare ground states in each magnetization sector of the prototypical XXZ ...
A Contextual Approach to Technological Understanding and Its Assessment
Eline de Jong, Sebastian De Haro·Mar 27, 2025
Technological understanding is not a singular concept but varies depending on context. Building on De Jong and De Haro's (2025) notion of technological understanding as the ability to realise an aim through the use of a technological artefact, this p...
Statistics of the Random Matrix Spectral Form Factor
Alex Altland, Francisco Divi, Tobias Micklitz +2 more·Mar 27, 2025
The spectral form factor of random matrix theory plays a key role in the description of disordered and chaotic quantum systems. While its moments are known to be approximately Gaussian, corrections subleading in the matrix dimension, $D$, have recent...
