21:01 Phys.org Cooling radio waves to their quantum ground state

Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the so-called laser cooling technique that is frequently used to cool atomic samples. The device used a recently developed technique the researchers call photon pressure coupling, which is predicted to be of use in detecting ultra-weak magnetic resonance (MRI) signals or for quantum-sensing applications that can help the search for dark matter. The results have been published in Science Advances.

17:31 Phys.org Fast flows prevent buildup of impurities on the edge of tokamak plasmas

Impurities in the plasmas in fusion tokamaks can reduce performance. These impurities are created by interactions between the hot plasma and the metal tokamak walls. These walls are often armored with tungsten. This material resists heat, but degrades over time, releasing impurities into the plasma. Simulations predict how these impurities behave, but they are difficult to measure directly because many impurities only emit weak levels of radiation. The experiment detailed here used a collector probe to sample the plasma. It determined that detrimental impurities accumulate in the region just outside the plasma edge only when the tokamak magnetic fields rotate around the donut-shaped tokamak in a counter-clockwise direction. This is the opposite direction that the plasma current moves. Clockwise rotation causes fast flows that remove the impurities.

These particles experience little resistance and travel freely past obstacles such as impurities, fabrication defects, a change of signal's trajectory within a circuit, or objects placed intentionally in the particles' path. That's because these particles, instead of being reflected by the obstacle, go around it "like river-water flowing past a rock," says Prof. Romain Fleury, head of EPFL's Laboratory of Wave Engineering, within the School of Engineering.

With those calculations, they can create 3D velocity maps and figure out the mineralogy and temperature of the observed regions. When a phase transition occurs in a mineral, such as a crystal structure change under pressure, scientists observe a velocity change, usually a sharp seismic velocity discontinuity.

They used pulses of radio waves to flip the spins of two nuclei in a molecule, with each spin's "up" or "down" orientation storing information in the way that a "0" or "1" state stores information in a classical data bit. In those early days of quantum computers, the combined orientation of the two nuclei—that is, the molecule's quantum state—could only be preserved for brief periods in specially tuned environments. In other words, the system quickly lost its coherence. Control over quantum coherence is the missing step to building scalable quantum computers.

19:29 Phys.org Levi­tating particles in a vacuum

Levitation of both large objects and of single atoms has become a widely used technique in science and engineering. In the last years, many researchers have started to explore a new horizon: the levitation of nano- and micro-particles—still smaller than the diameter of a single hair, but composed of billions of atoms—in vacuum.

16:45 Phys.org Controlling electrons and vibrations in a crystal with polarized light

The quantum behavior of atomic vibrations excited in a crystal using light pulses has much to do with the polarization of the pulses, say materials scientists from Tokyo Tech. The findings from their latest study offer a new control parameter for the manipulation of coherently excited vibrations in solid materials at the quantum level.
