What does quantum technology do?
Quantum technologies leverage principles from quantum mechanics, a fundamental theory in quantum physics that describes the behavior of matter and energy on the scale of atoms and subatomic particles. As we continue to harness the unique properties of quantum systems, a variety of quantum technologies have emerged, spanning computing, communications, and sensing, among others.
What are types of quantum technologies?
Quantum computing
Quantum computing is used to solve problems that are computationally infeasible for classical computers. Examples include factoring large numbers (which has implications for encryption), simulating quantum systems (useful for drug discovery and materials science), solving optimisation problems, and more.
Quantum cryptography and communication
Quantum key distribution, or QKD, involves creating and distributing encryption keys in such a way that any eavesdropping can be detected. Quantum secure direct communication, or QSDC, sends information directly without the need to generate and distribute a secret key. And quantum repeaters/quantum internet extend the range of quantum communication, eventually forming a network for securely transmitting quantum information across the globe.
Quantum sensing and metrology
Achieve ultra-precise measurements by harnessing quantum superposition and entanglement. High-precision atomic clocks, magnetic field sensors, and gravitational wave detectors are all examples.
Quantum imaging
Discovering new imaging modalities that can work under conditions where classical imaging fails. Examples include ghost imaging (where an object can be imaged without light directly interacting with it), super-resolution imaging beyond the classical diffraction limit, and quantum lidar.
Quantum simulation
Simulate complex quantum systems that are difficult or impossible to study analytically or simulate classically. These simulations can include molecular interactions for drug discovery, studying quantum phase transitions, and understanding high-temperature superconductors.
Quantum networking
Creating a network where quantum information is processed and exchanged, paving the way for a quantum internet. Parts of doing this include remote quantum computing tasks, distributed quantum sensing, and interconnecting quantum computers for more power.
