A Quantum Leap into the Future

– Unraveling the Quantum landscape in Australia

In the ever-evolving landscape of technology, Quantum Computing stands as a revolutionary force with the potential to redefine the capabilities of computation by utilising the principles of quantum mechanics.

Origin and Evolution of Quantum Computing

Quantum computing had its origins in the early 1980s when physicist Richard Feynman and computer scientist David Deutsch laid the theoretical groundwork for quantum computers.The concept of quantum bits or qubits, the fundamental units of quantum information, was introduced. Unlike classical bits that can exist in a state of 0 or 1, qubits can exist in multiple states simultaneously due to the principles of superposition and entanglement.

In the 1990s, Expanding upon the findings -

  • Peter Shor introduced algorithms that targeted breaking the prevalent RSA and Diffie–Hellman encryption protocols, garnering considerable interest in the realm of quantum computing.

  • Subsequently, Grover's algorithm showcased a quantum acceleration for the broadly relevant unstructured search problem.

  • Concurrently, Seth Lloyd demonstrated that quantum computers could simulate quantum systems without the exponential overhead inherent in classical simulations.

Over the years, researchers made significant strides in constructed small-scale developing quantum computer using superconductors. In 1998, a two-qubit quantum computer demonstrated the feasibility of the technology, and subsequent experiments have increased the number of qubits and reduced error rates.

In 2019, Google AI and NASA made a statement that they had achieved quantum supermacy with a 54-qubit machine, performing a computation that is impossible for any classical computer which is still active in research.

Evolution of Quantum Computing Initiatives in Australia

Australia has a strong history in quantum technology, standing at the forefront of research and development. Numerous companies, universities and research institutions alongside collaborations with global quantum leaders, are contributing to the growth of quantum computing capabilities in the country. Charting the Australian quantum landscape, a research paper published in 2019, states that Australia has more than two decades of support for quantum engineering, science, and technology has paved the way for significant scientific outputs and exciting translation efforts.

With this, Australian Research Council supports four national Centres of Excellence in quantum technology — the Centres for Engineered Quantum Science (EQUS), Exciton Science, Future Low-Energy Electronics Technologies (FLEET), and Quantum Computation and Communication Technology (CQC2T).

The ARC Centre of Excellence for Quantum Computation and Communication Technology, funded by the Australian Government is a clear example of where the country is heading in terms of a roadmap. It stands as a well as a trusted authority in the industry.
