Data re-uploading with a single qudit
Noah L. Wach, Manuel S. Rudolph, Fred Jendrzejewski +1
Quantum two-level systems, i.e. qubits, form the basis for most quantum machine learning approaches that have been proposed throughout the years. However, higher dimensional quantu…
Squeezing and quantum approximate optimization
Gopal Chandra Santra, Fred Jendrzejewski, Philipp Hauke +1
Variational quantum algorithms offer fascinating prospects for the solution of combinatorial optimization problems using digital quantum computers. However, the achievable performa…
Non-equilibrium dynamics of fluctuations in an ultra-cold atomic mixture
Apoorva Hegde, Robert Ott, Andy Xia +3
We investigate an ultra-cold mixture of Bose gases interacting via spin-changing collisions by studying the dynamics of spin fluctuations. The experimental implementation employs $…
Quantum approximate optimization algorithm for qudit systems
Yannick Deller, Sebastian Schmitt, Maciej Lewenstein +5
A frequent starting point of quantum computation platforms are two-state quantum systems, i.e., qubits. However, in the context of integer optimization problems, relevant to schedu…
Engineering a U(1) lattice gauge theory in classical electric circuits
Hannes Riechert, Jad C. Halimeh, Valentin Kasper +4
Lattice gauge theories are fundamental to such distinct fields as particle physics, condensed matter, and quantum information science. Their local symmetries enforce the charge con…
Cold atoms meet lattice gauge theory
Monika Aidelsburger, Luca Barbiero, Alejandro Bermudez +19
The central idea of this review is to consider quantum field theory models relevant for particle physics and replace the fermionic matter in these models by a bosonic one. This is…
