Quantum networks are networks that use the principles of quantum physics to transmit and process information.
What is the key feature of quantum networks?
The key feature of quantum networks is the ability to transmit and manipulate quantum information, such as qubits.
How are quantum networks different from classical networks?
Quantum networks differ from classical networks because they use quantum bits (qubits) to transmit and process information instead of classical bits.
What are the potential applications of quantum networks?
Potential applications of quantum networks include secure communication, quantum computing, and quantum cryptography.
What is entanglement in the context of quantum networks?
Entanglement is a phenomenon in quantum networks where two or more qubits become correlated and can no longer be described independently.
What is quantum teleportation in the context of quantum networks?
Quantum teleportation is a protocol used in quantum networks to transfer the quantum state of a qubit from one location to another.
What is quantum key distribution (QKD)?
Quantum key distribution (QKD) is a method used in quantum networks to securely share cryptographic keys using the principles of quantum mechanics.
What are some challenges in building quantum networks?
Some challenges in building quantum networks include quantum decoherence, error correction, and scaling up the network.
