Quantum protocols for Rabin oblivious transfer
Erika Andersson, Akshay Bansal, James T. Peat +2
Rabin oblivious transfer is the cryptographic task where Alice wishes to receive a bit from Bob but it may get lost with probability 1/2. In this work, we provide protocol designs…

Online learning of a panoply of quantum objects
Akshay Bansal, Ian George, Soumik Ghosh +2
In many quantum tasks, there is an unknown quantum object that one wishes to learn. An online strategy for this task involves adaptively refining a hypothesis to reproduce such an…
