IBM and ETH Zurich created a persistent spin helix for 1.1 nanoseconds

IBM and ETH Zurich managed to create a persistent spin helix - that kept the spin for 1.1 nanoseconds, enough for a full-cycle in a 1 Ghz processor. This is about 30 times longer than previously achieved.

The researchers managed to sustain the spin by using a gallium arsenide based semiconductor material and a very low temperature (-232C).
