Scalable, quantum-accessible, and adaptive pseudorandom quantum state and pseudorandom function-like quantum state generators
Rishabh Batra, Zhili Chen, Rahul Jain +1
We show new constructions for pseudorandom quantum states (PRS) and pseudorandom function-like quantum state (PRFS) generators satisfying scalability, which means the security para…

A robust and composable device-independent protocol for oblivious transfer using (fully) untrusted quantum devices in the bounded storage model
Rishabh Batra, Sayantan Chakraborty, Rahul Jain +1
We present a robust and composable device-independent (DI) quantum protocol between two parties for oblivious transfer (OT) using Magic Square devices in the bounded storage model…

Commitments are equivalent to statistically-verifiable one-way state generators
Rishabh Batra, Rahul Jain
One-way state generators (OWSG) are natural quantum analogs to classical one-way functions. We consider statistically-verifiable OWSGs (sv-OWSG), which are potentially weaker objec…
