Hidden cosets and applications to unclonable cryptography
Abstract In 2012, Aaronson and Christiano introduced the idea of hidden subspace states to
build public-key quantum money STOC'12. Since then, this idea has been applied to realize …

On the feasibility of unclonable encryption, and more
Unclonable encryption, first introduced by Broadbent and Lord (TQC'20), is a one-time
encryption scheme with the following security guarantee: any non-local adversary (A, B, C) …

Public key encryption with secure key leasing
We introduce the notion of public key encryption with secure key leasing (PKE-SKL). Our
notion supports the leasing of decryption keys so that a leased key achieves the decryption …

Cloning games: a general framework for unclonable primitives
The powerful no-cloning principle of quantum mechanics can be leveraged to achieve
interesting primitives, referred to as unclonable primitives, that are impossible to achieve …

New approaches for quantum copy-protection
Quantum copy-protection uses the unclonability of quantum states to construct quantum
software that provably cannot be pirated. copy-protection would be immensely useful, but …

Collusion resistant copy-protection for watermarkable functionalities
Copy-protection is the task of encoding a program into a quantum state to prevent illegal
duplications. A line of recent works studied copy-protection schemes under “1→ 2 attacks” …
