(ScienceAlert) Engineers in Australia have found a way to make these artificial atoms more stable, which in turn could produce more consistent quantum bits, or qubits – the basic units of information in a quantum system.
They have found a way to minimise the error rate caused by imperfections in the silicon. “What really excites us about our latest research is that artificial atoms with a higher number of electrons turn out to be much more robust qubits than previously thought possible, meaning they can be reliably used for calculations in quantum computers,” said quantum engineer Andrew Dzurak of the University of New South Wales (UNSW) in Australia.
“This is significant because qubits based on just one electron can be very unreliable.”
