What is Quantum Technology

Quantum technology is grounded in the principles of quantum mechanics—the branch of physics that explains the behaviours of particles, such as atoms and molecules, at the atomic and subatomic levels. These principles allow us to process information in radically new and more powerful ways.

In the first quantum revolution of the 20th century, scientists observed quantum properties that enabled development of technologies that have shaped the modern world. Devices such as lasers, the transistor, magnetic resonance imaging (MRI), GPS navigation and semiconductors are just a few examples of how the understanding of quantum mechanics led to practical innovations. These technologies became foundational in fields like electronics, telecommunications, medicine, and computing, forming the backbone of much of today's technological landscape.

The Second Quantum Revolution

Now, we stand at the threshold of the second quantum revolution, this era is marked by breakthroughs in fields like quantum computing, quantum sensing, and quantum communication. These advancements, driven by a deeper understanding of quantum mechanics and the ability to manipulate individual particles with extraordinary precision, are reshaping the future. Grounded in principles like superposition and entanglement, quantum technology has become a transformative field of research and innovation.

The rapid pace of development has already sparked significant investment from leading industry players and governments around the world. Australia has emerged as a key player in this ongoing revolution.
