Scientists with funding from the Simons Foundation produced a phase of matter that behaves as if it exists in two time dimensions, according to a press release by the institution published on Wednesday. The researchers created the strange material by shining a sequence of laser pulses inspired by the Fibonacci numbers […]

Quantum computer works with more than zero and one

The Innsbruck quantum computer stores information in individual trapped calcium atoms, each of which has eight states, of which the scientists have used up to seven for computing. Credit: Uni Innsbruck/Harald Ritsch We all learn from early on that computers work with zeros and ones, also known as binary information. […]
