The study of condensed matter systems in electronic systems within solid-state materials has a long history.
More recently, it has become possible to realize synthetic systems out of controllable components in ultracold atom or photonic systems.
We experimentally realized the Harper-Hofstadter (HH) model describing charged particles in a two-dimensional lattice with a transverse magnetic field using an atomic Bose-Einstein condensate in a highly elongated tube geometry, three sites in circumference.
The use of qubits to construct computers opens the door to dramatic computational speed ups for certain problems.
Starting with the development of microscopes which enabled
the discovery of bacteria time and again, physicists have discovered and
then harnessed natural phenomena and the proceeded to use them to
open new windows of observation into the life sciences. Examples include
Making local measurements on an entangled quantum many-body state is expected to reduce quantum entanglement. However, recently it was found that in the thermodynamic limit it is possible to robustly protect quantum entanglement from continuous local measurements.
Cold atoms and ions provide one of the best ways to build controllable quantum many-body systems as quantum computers and quantum simulators. Here we report on recent developments in programming quantum simulators with focus on hybrid classical-quantum scenarios.
