OPINION: Cybersecurity is essential for our future in a society that needs to safeguard information as much as possible for secure banking, safe transportation, and protected power grids.

Quantum information technology will transform data communication and processing. Here, quantum physics is exploited for new technologies to protect, transmit and process information. Classical cryptography relies on mathematically hard problems such as factoring which are so difficult to solve that classical computers can take decades. Quantum information technology allows for an alternative approach to this problem that will lead to a solution on a meaningful timescale, such as minutes in contrast to years. Quantum information technology allows for secure encoding and decoding governed by fundamental physics which is inherently unbreakable, not just hard to break.

Internationally, quantum information is taking off rapidly underlined by large government initiatives. At the same time there are commercial investments from companies such as Google, IBM, Microsoft and Lockheed Martin.

Due to long term strategic investments in leading academic groups Australia remains at the forefront globally and enjoys a national competitive advantage in quantum computing and cybersecurity. We should utilise the fact that Australia is a world leader and global player in quantum information science to provide many new high technology industries for its future.
