Physicists reach atomic-scale telegraphy with light

In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking work, the unit of frequency was named “Hertz” in 1930. Hertz’s findings were later used by Guglielmo Marconi (Nobel Prize in

Physicist achieve milestone in quantum simulation with circular Rydberg qubits

A team of researchers from the 5th Institute of Physics at the University of Stuttgart is making important progress in the field of quantum simulation and quantum computing based on Rydberg atoms by overcoming a fundamental limitation: the limited lifetime of Rydberg atoms. Circular Rydberg states are showing enormous potential for overcoming this limitation.Quantum Physics
