Engineers at the University of New South Wales (UNSW) have created a new quantum bit that will open up new avenues to build and operate the super powerful quantum computers of the future.
The quantum bit 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.
“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 & 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.”
Building a quantum computer has been called the ‘space race of the 21st century’ – a difficult and ambitious challenge with the potential to deliver revolutionary tools for tackling otherwise impossible calculations, such as the design of complex drugs and advanced materials, or the rapid search of massive, unsorted databases.
Since the UNSW device is built using standard silicon technology, this result paves the way for the construction of powerful and reliable quantum processors based on the same fabrication process already used for today’s computers.
