QMA vs. QCMA and Pseudorandomness

Jiahui Liu, Saachi Mutreja, Henry Yuen

We study a longstanding question of Aaronson and Kuperberg on whether there exists a classical oracle separating from . Settling this question in eith…

Quantum State Group Actions

Saachi Mutreja, Mark Zhandry

Cryptographic group actions are a leading contender for post-quantum cryptography, and have also been used in the development of quantum cryptographic protocols. In this work, we e…

CountCrypt: Quantum Cryptography between QCMA and PP

Eli Goldin, Tomoyuki Morimae, Saachi Mutreja +1

We construct a unitary oracle relative to which but quantum-computation-classical-communication (QCCC) commitments and QCCC multiparty non-interactive…

Revocable Encryption, Programs, and More: The Case of Multi-Copy Security

Prabhanjan Ananth, Saachi Mutreja, Alexander Poremba

Fundamental principles of quantum mechanics have inspired many new research directions, particularly in quantum cryptography. One such principle is quantum no-cloning which has led…

On the Communication Complexity of Secure Multi-Party Computation With Aborts

James Bartusek, Thiago Bergamaschi, Seri Khoury +2

A central goal of cryptography is Secure Multi-party Computation (MPC), where parties desire to compute a function of their joint inputs without letting any party learn about t…

On black-box separations of quantum digital signatures from pseudorandom states

Andrea Coladangelo, Saachi Mutreja

It is well-known that digital signatures can be constructed from one-way functions in a black-box way. While one-way functions are essentially the minimal assumption in classical c…
