*Quantum Information*, unlike [[Classical Information|classical information]], is processed using [[Qubit|qubits]] that utilize quantum properties such as [[Superposition|superposition]] and [[Entanglement|entanglement]]. Entanglement can lead to correlations between quantum systems that have no classical counterpart and underlie proposed technologies such as [[Quantum Network|quantum networks]], [[Quantum Computer|quantum computers]], [[Quantum Metrology|quantum metrology]] and [[Quantum Simulation|quantum simulation]]. However, because of the no-cloning theorem, qubits cannot be perfectly copied. This constraint is both a challenge and an asset, making [[Quantum Communication|quantum communication]] highly secure but also requiring entirely new [[Quantum Error Correction|error-correction strategies]] in quantum computing. Despite these difficulties, quantum information holds the promise of revolutionary capabilities in cryptography, sensing, and computation for specific classes of problems. >[!read]- Further Reading >[!ref]- References
