Scientists at Oxford University have developed a method to generate the shortest ever single-photon pulse by removing the interference of quantum entanglement. So how big are these tiny record-breakers? They are 20 microns long (or 0.000001 metres), with a period of 65 femtoseconds (65 millionths of a billionth of a second). This experiment smashes the [...]
