Engineers show that a jellybean-shaped quantum dot creates more breathing space in a microchip packed with qubits.

Hot qubits made in Sydney break one of the biggest constraints to practical quantum computers

16 Apr 2020

A proof-of-concept published today in Nature promises warmer, cheaper and more robust quantum computing. And it can be manufactured using conventional silicon chip foundries.

Quantum computers: 10-fold boost in stability achieved

18 Oct 2016

UNSW engineers have created a new quantum bit that remains in a stable superposition for 10 times longer than previously achieved, dramatically expanding the number of calculations that could be performed in a future silicon quantum computer.

The “Dressed Qubit” - breakthrough in quantum state stability

17 Oct 2016

Engineers from UNSW’s Centre for Quantum Computation & Communication Technology (CQC2T) have created a new quantum bit which 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

Breakthrough opens door to affordable quantum computers

13 Apr 2015

A UNSW-led research team has encoded quantum information in silicon using simple electrical pulses for the first time, bringing affordable large-scale quantum computers one step closer to reality.
