Quantum cryptography is a secure communication method that relies on the principles of quantum mechanics to transmit cryptographic keys between parties in a way that is provably secure against eavesdropping. It typically involves the exchange of quantum states, such as entangled photons, to establish a shared secret key, which can then be used for secure communication using classical encryption techniques.

Quantum computing is a revolutionary paradigm of computation that utilizes the principles of quantum mechanics to perform calculations and solve problems at speeds far exceeding those of classical computers. Unlike classical computers, which manipulate bits that are either 0 or 1, quantum computers use quantum bits or qubits, which can exist in superpositions of 0 and 1 simultaneously. This allows quantum computers to explore multiple solutions simultaneously and solve certain problems exponentially faster than classical computers.
