(ZDNet) In a new study, researchers from Australia and Canada have identified a ‘sweet spot’, using holes, where the qubit is least sensitive to noise. The Australian Research Council (ARC) Centre of Excellence in Future Low-Energy Electronics Technologies (FLEET) said the work indicates holes are the solution to operational speed/coherence trade-off.
A team of Australian and Canadian researchers have published a new study they say demonstrates a path towards scaling individual quantum bits (qubits) to a mini-quantum computer by using holes.
It would be the harbinger of an entirely new medium of calculation, harnessing the powers of subatomic particles to obliterate the barriers of time in solving incalculable problems.
“One way to make a quantum bit is to use the ‘spin’ of an electron, which can point either up or down. To make quantum computers as fast and power-efficient as possible we would like to operate them using only electric fields, which are applied using ordinary electrodes,” FLEET said, alongside researchers from the ARC Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) hosted by the University of New South Wales (UNSW), and participants from the University of British Columbia.
