Neutral atom innovations by quantum systems accelerator mark quantum computing milestones
QSA All Personnel Meeting 2024. Credit: Berkeley Lab Before quantum computers can solve complex problems, researchers must develop technologies that manage larger numbers of qubits (the building blocks of quantum…
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…
