More importantly, qubits are made up of quantum particles and are subject to quantum entanglement, which allows for computing using coupled probabilities.
Quantum computers operate by using superposition, interference, and entanglement to perform complex calculations. Instead of using classical bits, quantum computing uses quantum bits, or qubits, which take on quantum properties of probability, where the bit is both zero and one, with coefficients of likelihood, until measured, in which their discrete value is determined. More importantly, qubits are made up of quantum particles and are subject to quantum entanglement, which allows for computing using coupled probabilities. With these phenomena, quantum computing opens the field of special quantum algorithms development to solve new problems, ranging from cryptography, to search engines, to turbulent fluid dynamics, and all the way to directly simulating quantum mechanics, allowing for the development of new pharmaceutical drugs.
