Sentences with phrase «quantum networks»
"quantum networks" refers to a type of communication system that uses the principles of quantum mechanics. Unlike traditional networks that transmit information as bits (1s and 0s), quantum networks use quantum bits or qubits that can represent multiple states at once. These networks have the potential to provide more secure communication and faster processing speeds for complex tasks like cryptography and data transfer. Full definition
