Abstract: We explore the problem of traitor tracing where the pirate decoder can contain a quantum state. Our main results include: - We show how to overcome numerous definitional challenges to give a meaningful notion of tracing for quantum decoders - We give negative results, demonstrating barriers to adapting classical tracing algorithms to the quantum decoder setting. - On the other hand, we show how to trace quantum decoders in the setting of (public key) private linear broadcast encryption, capturing a common approach to traitor tracing.
