Investigating a (3+1)D Topological -Term in the Hamiltonian Formulation of Lattice Gauge Theories for Quantum and Classical Simulations
Angus Kan, Lena Funcke, Stefan Kühn +5
Quantum technologies offer the prospect to efficiently simulate sign-problem afflicted regimes in lattice field theory, such as the presence of topological terms, chemical potentia…
A measurement-based variational quantum eigensolver
Ryan R. Ferguson, Luca Dellantonio, Karl Jansen +3
Variational quantum eigensolvers (VQEs) combine classical optimization with efficient cost function evaluations on quantum computers. We propose a new approach to VQEs using the pr…
A resource efficient approach for quantum and classical simulations of gauge theories in particle physics
Jan F. Haase, Luca Dellantonio, Alessio Celi +4
Gauge theories establish the standard model of particle physics, and lattice gauge theory (LGT) calculations employing Markov Chain Monte Carlo (MCMC) methods have been pivotal in…
High dimensional measurement device independent quantum key distribution on two dimensional subspaces
Luca Dellantonio, Anders S. Sørensen, Davide Bacco
Quantum key distribution (QKD) provides ultimate cryptographic security based on the laws of quantum mechanics. For point-to-point QKD protocols, the security of the generated key…
