Public-Key Quantum Fire and Key-Fire From Classical Oracles
Alper Ãakan, Vipul Goyal, Omri Shmueli
Quantum fire is a distribution of quantum states that can be efficiently cloned, but cannot be efficiently converted into a classical string. First considered by Nehoran and Zhandr…
Multi-Copy Security in Unclonable Cryptography
Alper Ãakan, Vipul Goyal, Fuyuki Kitagawa +2
Unclonable cryptography leverages the quantum no-cloning principle to copy-protect cryptographic functionalities. While most existing works address the basic single-copy security,…
Anonymous Public-Key Quantum Money and Quantum Voting
Alper Cakan, Vipul Goyal, Takashi Yamakawa
Quantum information allows us to build quantum money schemes, where a bank can issue banknotes in the form of authenticatable quantum states that cannot be cloned or counterfeited.…
Unclonable Secret Sharing
Prabhanjan Ananth, Vipul Goyal, Jiahui Liu +1
Unclonable cryptography utilizes the principles of quantum mechanics to addresses cryptographic tasks that are impossible classically. We introduce a novel unclonable primitive in…
