Statistically secure uncloneable encryption of arbitrary messages
Archishna Bhattacharyya, Anne Broadbent, Eric Culf
Unconditional uncloneable encryption of a single bit with efficient encryption and decryption is now possible. However, whether the extension to messages of arbitrary length achiev…

The uncloneable bit exists
Archishna Bhattacharyya, Anne Broadbent, Eric Culf
We establish quantum uncloneable encryption with unconditional security, preventing two non-communicating adversaries from simultaneously decrypting a single ciphertext even wh…
