Continuous variable quantum reservoir computing: quantum light with memory

Figure : The transfer of an electron (orange) between two atoms, triggered by a light pulse (green), causes a local distortion in the crystal structure, which then spreads throughout the crystal.

Understanding the transformation of a material using ultrashort laser pulses: from quantum physics to thermodynamics

Figure : Nanoscale analysis using atomic force microscopy of two regions of the material with different properties: coercivity indicates the material's resistance to loss of magnetisation.

If you want to optimise your magnet, look below the micron scale...

Figure: above: the trimodal velocity distribution from the experiment. The large peak in the middle represents the Bose-Einstein condensate, and on either side, carrying opposite velocities, are the phonons created by parametric excitation. Below are the individual phonons (blurred spheres) and a diagram representing their entanglement.

Simulation of the early universe in a Bose-Einstein condensate

Schematic representation of the principle behind the experiment. A laser excites a crystal defect in a sheet of hBN, composed of boron atoms (in red) and nitrogen atoms (in blue). The emitted photons are separated from the reflected laser using a polariser. These photons, emitted under resonant excitation, have properties that are particularly favourable for quantum information.
