The emerging domain of parallelized quantum information processing opens up new possibilities for precise measurements, communication and imaging. Precise control of multiple stored photons allows efficient handling of this subtle information in large amounts. In the Quantum Memories Laboratory at Faculty of Physics, University of Warsaw a group of laser-cooled atoms has been used as a memory which can store simultaneously up to 665 quantum states of light. The experimental results have been published in a prestigious Nature Communications journal.
Article describes development of a deep learning neural network to predict disruptions on fusion plasmas.
ICFO researchers create a novel type of liquid one hundred million times more dilute than water and one million times thinner than air. The experiments, published in Science, exploit a fascinating quantum effect to produce droplets of this exotic phase of matter.
You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a UC Berkeley team showed that for a polarizable atom, the opposite occurs: the hot object attracts it. Using an atom interferometer, they found the attraction was 20 times stronger than the gravitational attraction between a tungsten object and a cesium atom. Though negligible in most situations, next-generation gravitational wave experiments may have to take this into account.
Excitonium has a team of researchers at the University of Illinois at Urbana-Champaign... well... excited! Professor of Physics Peter Abbamonte and graduate students Anshul Kogar and Mindy Rak, with input from colleagues at Illinois, University of California, Berkeley, and University of Amsterdam, have proven the existence of this enigmatic new form of matter, which has perplexed scientists since it was first theorized almost 50 years ago.
The triple axis spectrometer FLEXX at BER II provides a new detector module for user service. It measures many angles and multiple energy transfers simultaneously and thus increases the amount of data measured per hour by about a factor of ten. This enables neutron users to make optimal use of their beam time.
Scientists from the European Graphene Flagship, led by researchers at ICFO- The Institute of Photonic Sciences, have recently succeeded in observing and following, in real-time, the way in which heat transport occurs in van der Waals stacks, which consist of graphene encapsulated by the dielectric two-dimensional material hexagonal BN (hBN).
A team of Korean researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has presented a new synthetic protocol to produce three-dimensional porous organic materials in the blink of an eye, like firing bullets.
In quantum materials, periodic stripe patterns can be formed by electrons coupled with lattice distortions. To capture the extremely fast dynamics of how such atomic-scale stripes melt and form, Berkeley Lab scientists used femtosecond-scale laser pulses at terahertz frequencies. Along the way, they found some unexpected behavior.
Physicists at MIT and Harvard University have demonstrated a new way to manipulate quantum bits of matter. In a paper published in the journal Nature, they report using a system of finely tuned lasers to first trap and then tweak the interactions of 51 individual atoms, or quantum bits.
