Quantum technology works by using the principles of quantum mechanics – the physics of sub-atomic particles – notably quantum entanglement and quantum superposition. Challenging though it may sound, it is not a prerequisite to fully understand quantum in its entirety to benefit from the technology. Essentially, quantum technology has the potential to offer solutions that are faster, more complex, more secure, and more precise than traditional technologies. By 2035, the estimated economic value at stake from quantum computing could be greatest in sectors such as chemicals, financial services, and transportation.
