A star like a Matryoshka doll: New theory for gravastars

 Quantum Physics News
 15 February 2024
If gravitational condensate stars (or gravastars) actually existed, they would look similar to black holes to a distant observer. Two theoretical physicists have now found a new solution to Albert Einstein's theory of general relativity, according to which gravitational stars could be structured...

Fundamental equation for superconducting quantum bits revised

 Quantum Physics News
 14 February 2024
Physicists have uncovered that Josephson tunnel junctions -- the fundamental building blocks of superconducting quantum computers -- are more complex than previously thought. Just like overtones in a musical instrument, harmonics are superimposed on the fundamental mode. As a consequence,...

New technique measures structured light in a single shot

 Quantum Physics News
 08 August 2023
Structured light waves with spiral phase fronts carry orbital angular momentum (OAM), attributed to the rotational motion of photons. Recently, scientists have been using light waves with OAM, and these special "helical" light beams have become very important in various advanced technologies like...

Telecom-band-integrated multimode photonic quantum-memory

 Quantum Physics News
 31 July 2023
Quantum memory that depends on quantum-band integration is a key building block used to develop quantum networks that are compatible with fiber communication infrastructures. Quantum engineers and IT specialists have yet to create such a network with large capacity to form an integrated multimode...
