Quantum Computer May Be Closer With Extended Quantum Lifetime Of Electrons

Physicists in the USA and at the London Centre for Nanotechnology have found a way to extend the quantum lifetime of electrons by more than 5,000 per cent, as reported recently in Physical Review Letters. Electrons exhibit a property called 'spin' and work like tiny magnets which can point up, down or a quantum superposition of both. The state of the spin can be used to store information and so by extending their life the research provides a significant step towards building a usable quantum computer.

For anyone following quantum computing, this development is exciting indeed
