Quantum computers will someday perform calculations impossible for conventional digital computers. But for that to happen, the core quantum information must be preserved against contamination from the environment. In other ...

(Phys.org) —Although mass may seem to be a fairly straightforward concept, from a physics perspective it can be much more complex than weighing an object and reading off a number in grams. For instance, an object's mass ...
Nippon Telegraph and Telephone has proposed a method for generating a large-scale entangled quantum state of ultracold atoms in an optical lattice with high fidelity and short operation time, which becomes a resource for ...

It is advantageous to implement a quantum bit (qubit) with a single nuclear spin because the nuclear spin is robust against any stray magnetic fields. This robustness can be attributed to the small magnitude of the magnetic ...

Physicists in Darmstadt have been able to stop something that has the greatest possible speed and that never really stops. We're talking about light. Already a decade ago, physicists stopped it very for a short moment. In ...
