quantum encryption

Quantum encryption, also known as quantum cryptography, is a method of secure communication that uses principles of quantum mechanics to protect information. It leverages quantum phenomena like superposition and entanglement to ensure that any attempt to eavesdrop on a communication will be detectable. This makes it a highly secure form of encryption, with the potential to break current encryption schemes and enable new forms of secure communication.1

Quantum computers, which are still largely experimental, utilize quantum bits, or qubits, that can exist in multiple states simultaneously due to superposition. This allows them to perform many calculations at once, making them potentially much faster than classical computers for certain tasks. However, building and maintaining these computers is challenging due to issues like decoherence, where qubits lose their quantum properties through environmental interactions.12
