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…
