From stationary to flying qubits at speeds never reached before…. This feat, achieved by a team from Polytechnique Montréal and France?s Centre national de la recherche scientifique (CNRS), brings us a little closer to the era when information is transmitted via quantum principles.

A paper titled ?High-Fidelity and Ultrafast Initialization of a Hole-Spin Bound to a Te Isoelectronic Centre in ZnSe? was recently published in the journal Physical Review Letters. The creation of a qubit in zinc selenide, a well-known semi-conductor material, made it possible to produce an interface between quantum physics that governs the behaviour of matter on a nanometre scale and the transfer of information at the speed of light, thereby paving the way to producing quantum communications networks.

Classical physics vs. quantum physics

In today?s computers, classical physics rules. Billions of electrons work together to make up an information bit: 0, electrons are absent and 1…
