Researchers create a one-dimensional gas out of light
The polymers applied to the reflective surface trap the photon gas in a parabola of light. The narrower this parabola is, the more one-dimensionally the gas behaves. Credit: IAP/Uni Bonn…
Major leap for nuclear clock paves way for ultraprecise timekeeping
A powerful laser shines into a jet of gas, creating a bright plasma and generating ultraviolet light. The light leaves a visible white line as it interacts with leftover gas…
Cold-atom simulator demonstrates quantum entanglement between electronic and motional states
Atoms in the optical lattice, trapped at a distance of 0.5 micron, are excited to the Rydberg state by the ultrafast excitation technique. Interaction between close Rydberg atoms results in…
A device to sort photon states could be useful for quantum optical computer circuits
Credit: Natasha Tomm et al To build light-based quantum technologies, scientists and engineers need the ability to generate and manipulate photons as individuals or a few at a time. To…
Higher-order topological simulation unlocks new potential in quantum computers
By compressing quantum information in a large three-dimensional (3D) single particle (1P) lattice system into a one-dimensional (1D) spin chain with three interacting particles (3P), quantum materials can be accurately…
Using a gamma ray burst to search for violations of Einstein’s relativity postulates
Credit: Unsplash/CC0 Public Domain Einstein’s theory of relativity is based on two assumptions, or postulates. The first is that the laws of physics look the same to everyone traveling in…
Novel encoding mechanism unveiled for particle physics
In high-energy heavy-ion collision experiment and simulation, thousands of particles are generated and recorded in one event. It is necessary to provide unique codes to register different particles that contain…
