Evolution of hybrid quantum-classical wavefunctions
François Gay-Balmaz, Cesare Tronci
A gauge-invariant wave equation for the dynamics of hybrid quantum-classical systems is formulated by combining the variational setting of Lagrangian paths in continuum theories wi…
Non-Markovian Dynamics of a Single Excitation within Many-Body Dissipative Systems
Adam Burgess, Marian Florescu
We explore the dynamics of coupled atoms to a generic bosonic reservoir under specific system symmetries. In the regime of multiple atoms coupled to a single reservoir with ide…
Scalable and robust quantum computing on qubit arrays with fixed coupling
Nguyen H. Le, Max Cykiert, Eran Ginossar
We propose a scheme for scalable and robust quantum computing on two-dimensional arrays of qubits with fixed longitudinal coupling. This opens the possibility for bypassing the dev…
Matrix Model simulations using Quantum Computing, Deep Learning, and Lattice Monte Carlo
Enrico Rinaldi, Xizhi Han, Mohammad Hassan +4
Matrix quantum mechanics plays various important roles in theoretical physics, such as a holographic description of quantum black holes. Understanding quantum black holes and the r…
PT symmetry and the evolution speed in open quantum systems
Dorje C. Brody
The dynamics of an open quantum system with balanced gain and loss is not described by a PT-symmetric Hamiltonian but rather by Lindblad operators. Nevertheless the phenomenon of P…
Symmetric and antisymmetric kernels for machine learning problems in quantum physics and chemistry
Stefan Klus, Patrick Gelß, Feliks Nüske +1
We derive symmetric and antisymmetric kernels by symmetrizing and antisymmetrizing conventional kernels and analyze their properties. In particular, we compute the feature space di…
