Quantum optical cooling of nanoparticles

When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, ...

Quasiparticles experimentally shown to interfere for first time

Qubits, the units used to encode information in quantum computing, are not all created equal. Some researchers believe that topological qubits, which are tougher and less susceptible to environmental noise than other kinds, ...

Repulsive photons

Light particles normally do not "feel" each other because there is no interaction acting between them. Researchers at ETH have now succeeded in manipulating photons inside a semiconductor material in such a way as to make ...

Questions in quantum computing—how to move electrons with light

Electronics rely on the movement of negatively-charged electrons. Physicists strive to understand the forces that push these particles into motion, with the goal of harnessing their power in new technologies. Quantum computers, ...

Breaching the horizons: Universal spreading laws confirmed

The universal laws governing the dynamics of interacting quantum particles are yet to be fully revealed to the scientific community. A team of researchers at the Center for Theoretical Physics of Complex Systems (PCS), within ...
