Whether you need a new villain or an old Spider-Man, your sci-fi movie will sound more scientifically respectable if you use the word "multiverse." The Marvel multiverse puts different versions of our universe "out there," somewhere. In these films, with the right blend of technology, magic, and...

Bilayer graphene inspires two-universe cosmological model

While quantum computers represent a revolution in computation, they can't communicate with each other the way regular computers can—over the internet. If quantum computers could be connected through a quantum network, they could facilitate perfectly secure communication between more than two parties...

Single photon emitter takes a step closer to quantum tech

 Quantum Physics News
 05 May 2022
To get closer to quantum technology we need to develop non-classical light sources that can emit a single photon at a time and do so on demand. Scientists at EPFL have now designed one of these "single photon emitters" that can work at room temperature and is based on quantum dots grown on...

Mechanism 'splits' electron spins in magnetic material
