Quantum refers to the fundamental principles governing the behaviour of matter and energy at the smallest scales. On this page you will gain a basic understanding of what the so called quantum technologies are and in which various fields they will shape the future of our society. Whether you are a curious beginner or an enthusiast seeking deeper insights, we have courses for you to learn more about quantum!
Quantum Phenomena
Quantum technologies harness the principles of quantum mechanics to build powerful tools for processing information. These are the technologies driven from engineering the individual quantum states.
Qubit
It is the quantum analogue of the classical bit. While a bit can only take the value 0 or 1, a qubit can also exist in a combination (superposition) of both.
Measurement
The ability of a quantum system to exist in multiple possibilities simultaneously. For example, a qubit can be in 0 and 1 at the same time.
Superposition
When measuring a quantum system, we do not observe the superposition directly: the superposition collapses and the system takes on a definite value. This process is probabilistic, and the probability of each outcome is determined by the superposition prior to measurement.
Entanglement
Two or more quantum particles can be correlated in such a way that measuring one instantly determines the state of the other, even if they are separated by great distances.
Tunneling
Quantum particles have a nonzero probability of passing through barriers even without having the necessary energy. This phenomenon is key in processes such as nuclear fusion and in electronic devices like the scanning tunneling microscope.
Quantum Technologies
Thanks to the control at a single particle level of the above quantum phenomena, quantum is reshaping the technology landscape and our understanding of the universe through the following new domains.
