Quantum computing is a type of computing that uses quantum mechanics to perform operations on data. Quantum computing has the potential to solve complex problems that are currently infeasible for classical computers, such as cryptography and drug discovery. Quantum computing hardware is still in the experimental phase, but popular quantum computing platforms include IBM Quantum, D-Wave, and Rigetti.
