Measurement and Control of the Complex Berry Phase in a Quantum System
Pratik J. Barge, Qian Cao, Niklas Hörnedal +2
The Berry phase is a geometric phase acquired during adiabatic evolution over a closed loop in parameter space. It plays an essential role in geometric quantum gates and other phas…
Förster resonance energy transfer with transient coherent effects
Maximilian Meyer-Mölleringhof, Pablo Martinez-Azcona, Aurélia Chenu +1
We formulate the weak intramolecular coupling Förster resonance energy transfer theory in a form suitable for calculating ultrafast nonlinear response of molecular systems. We intr…
Exploring the topology of a non-Hermitian superconducting qubit using shortcuts to adiabaticity
Serra Erdamar, Maryam Abbasi, Weijian Chen +3
Open quantum systems described by a non-Hermitian Hamiltonian exhibit rich dynamics due to the topology of their complex energy spectrum. By encircling an exceptional point degener…
Magic Steady State Production: Non-Hermitian, Dissipative, and Stochastic Pathways
Pablo Martinez-Azcona, Matthieu Sarkis, Alexandre Tkatchenko +1
Universal quantum computers require entanglement and non-stabilizerness, a resource known as \textit{quantum magic}. Here, we introduce a protocol that prepares magic steady states…
Surmise for random matrices' level spacing distributions beyond nearest-neighbors
Ruth Shir, Pablo Martinez-Azcona, Aurélia Chenu
Correlations between energy levels can help distinguish whether a many-body system is of integrable or chaotic nature. The study of short-range and long-range spectral correlations…
Two transitions in complex eigenvalue statistics: Hermiticity and integrability breaking
G. Akemann, F. Balducci, A. Chenu +3
Open quantum systems have complex energy eigenvalues which are expected to follow non-Hermitian random matrix statistics when chaotic, or 2-dimensional (2d) Poisson statistics when…
