Quantum computer

The quantum interference experiment as seen under an electron microscope. Using bilayer graphene, scientists controlled the trajectory of an anion in the material (in red). They made its wave go around an island containing a magnetic field and other anions (in green) and then brought it back together with the original wave to study its properties. The electrical gates (in dark gray) allow scientists to direct the anions along specific paths in the material and also determine the density of electrons in the island.

Weizmann Institute scientists identify quantum "memory particles" – a step towards a durable quantum computer

Weizmann Institute of Science scientists have found new evidence for the existence of a system of particles that "remembers" which quantum states it was in before, taking another step toward a fault-tolerant quantum computer.
The institute's scientists were looking for how to establish an efficient method for processing information in quantum computers - and unexpectedly discovered a new type of vortices that are created when two photons collide
