"Engineers at the University of New South Wales (UNSW) have created a new quantum bit that remains in a stable superposition for 10 times longer than previously achieved, dramatically expanding the time during which calculations could be performed in a future silicon quantum computer."

'The new quantum bit, made up of the spin of a single atom in silicon and merged with an electromagnetic field – known as dressed qubit – retains quantum information for much longer that an undressed atom, opening up new avenues to build and operate the superpowerful quantum computers of the future.

'The results are published today in the international journal, Nature Nanotechnology.

'“We have created a new quantum bit where the spin of a single electron is merged together with a strong electromagnetic field,” said Arne Laucht, a Research Fellow at the School of Electrical Engineering and Telecommunications at UNSW, and lead author of the paper. “This quantum bit is more versatile and more long-lived than the electron alone, and will allow us to build more reliable quantum computers.”'
