Distributed quantum sensor network achieves ultra-high resolution near Heisenberg limit
Generation of multi-mode N00N states using bell states generated by the Sagnac interferometer and transmission of the generated entanglement states to each mode. Estimation of the average of two phases…
Microscopic ‘ocean’ on a chip reveals new nonlinear wave behavior
Electron microscope image of the superfluid wave tank used in the experiments (blue) coupled to an optical fibre which brings laser light in and out of the device. The zoom-in…
Simulations hint at new strongly correlated states of matter in ultracold polar molecules
A self-bound crystal of individual dipolar molecules surrounded by a superfluid ring. I have made the figure myself, based on simulation data. Credit: Ciardi et al. Bose-Einstein condensates (BECs) are…
A ‘seating chart’ for atoms helps locate their positions in materials
MIT physicists have developed discrete grid imaging technique (DIGIT), an optical super-resolution technique that maps quantum emitters to lattice sites with atomic localization precision (as represented in this artist’s interpretation).…
Electrons that can’t find the exit
How can a frog escape from a box? It needs to have enough energy—and it has to find the exit. Credit: Vienna University of Technology What happens when electrons leave…
