Resource requirements of private quantum channels and consequence for oblivious remote state preparation
Rahul Jain
Shannon in celebrated works had shown that n bits of shared key is necessary and sufficient to transmit n-bit classical information in an information-theoretically secure way. Amba…
On divergence, relative entropy and the substate property
Rahul Jain, Jaikumar Radhakrishnan, Pranab Sen
In this article we study relationship between three measures of distinguishability of quantum states called as divergence, relative entropy and the substate property.
Distinguishing sets of quantum states
Rahul Jain
Given two sets finite and of quantum states. We show necessary and sufficient conditions for distinguishing them by a measurement.
Improved direct sum theorem in classical communication complexity
Rahul Jain
Withdrawn due to critical error.
Communication complexity of remote state preparation with entanglement
Rahul Jain
We consider the problem of remote state preparation recently studied in several papers. We study the communication complexity of this problem, in the presence of entanglement and i…
A direct sum theorem in communication complexity via message compression
Rahul Jain, Jaikumar Radhakrishnan, Pranab Sen
We prove lower bounds for the direct sum problem for two-party bounded error randomised multiple-round communication protocols. Our proofs use the notion of information cost of a p…
