Computational Security of Quantum Encryption

Understand

Quantum-mechanical devices have the potential to transform cryptography.

• Most research in this area has focused either on the information-theoretic advantages of quantum protocols or on the security of classical cryptographic schemes against quantum attacks.
• In this work, we initiate the study of another relevant topic: the encryption of quantum data in the computational setting.
• In this direction, we establish quantum versions of several fundamental classical results.
