Quantum logic gate in silicon built for the for the first time, making calculations between 2 qubits of information possible – and thereby clearing the final hurdle to making silicon quantum computers a reality. “What we have is a game changer,” said Andrew Dzurak, Scientia Professor and Director of the Australian National Fabrication Facility at UNSW. “Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs, which rely on more exotic technologies.”

In classical computers, data is rendered as binary bits, which ...

First time wavelike behavior of room-temp polariton condensate has been demonstrated in the lab on a macroscopic length scale: a significant development in understanding and manipulation of quantum objects.

Quantum mechanics tells us objects have both particle and wavelike behaviour with a wavelength inversely proportional to the object’s velocity…at atomic length scales, except with bosons, particles of a particular type that can be combined in large numbers in the same quantum state, it is possible to form macroscopic-scale quantum objects, called Bose-Einstein condensates. These are at the root of quantum physics’ superfluidity and superconductivity...
