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.



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.



CQC²T is dedicated to developing the next generation of scientists to join us in the race to build a scalable quantum computer. The Centre provides opportunities for students to develop their passion for maths and physics.



Keen to know the latest activities from our teams around Australia? CQC²T new focuses on our latest research, outreach activities, awards and staff and students in the spotlight. Read all our latest updates.



Our calendar of events is designed for physicists and future physicists to seek opportunities for their learning and growth. View the latest conferences, workshops, open days and school events here.



To achieve our goals dedicated team members are needed at Centre nodes around Australia. Enquire now to be part of our talented national team in this dynamic ever-changing industry.
