Cryptography in the Common Haar State Model: Feasibility Results and Separations
Prabhanjan Ananth, Aditya Gulati, Yao-Ting Lin
Common random string model is a popular model in classical cryptography. We study a quantum analogue of this model called the common Haar state (CHS) model. In this model, every pa…

Pseudorandom Isometries
Prabhanjan Ananth, Aditya Gulati, Fatih Kaleoglu +1
We introduce a new notion called -secure pseudorandom isometries (PRI). A pseudorandom isometry is an efficient quantum circuit that maps an -qubit state to an …
