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 prestigious 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.
