What is quantum computing?

Imagine a medical drug designed to match your own personal biochemistry. Or being able to undertake sophisticated analysis of traffic patterns to prevent gridlock and cut down on travel time in major cities.

Quantum computers have the potential to solve problems in minutes that would take conventional computers centuries. This would have a transformational impact on Australian and global businesses, from banks undertaking financial analysis, transport companies planning optimal logistic routes, or improvements in medical drug design.

The advantage of a quantum computer is that information can be stored in a large number of different states at the same time. Classical computers store information as bits that represent either a ‘1’ or a ‘0’, but relying on the effects of quantum physics, qubits (quantum bits) in a quantum computer could be ‘1’ or ‘0’, or ‘1’ and ‘0’ at the same time.

The CQC2T was the first team to build a quantum logic gate in silicon, which is a critical step towards making silicon quantum computers a reality.
