Quantum operations with 99% fidelity – the key to practical quantum computers

Quantum computers can solve useful problems only if there is less than 1 error every 100 operations, which means 99% operation fidelity.

ABOUT US

There is an international race to build a scalable, quantum computer that transcends the capacity of conventional computers. A technology that has the potential to transform the information economy and create the industries of the future – solving complex solutions in hours or minutes.

The Australian Research Council (ARC) Centre of Excellence for Quantum Computation and Communication Technology (CQC²T) is focused on delivering world-leading quantum research to develop full-scale quantum systems.
