MPC in the Quantum Head (or: Superposition-Secure (Quantum) Zero-Knowledge)
Quantum 10, 2161 (2026). The MPC-in-the-head technique (Ishai et al., STOC 2007) is a celebrated method to build zero-knowledge protocols with desirable theoretical properties and high practical efficiency. This technique has generated a large body of research and has influenced the design of real-world post-quantum cryptographic signatures. In this work, we
