Security proof for parallel DIQKD
Ashutosh Marwah, Frédéric Dupuis
We present a parallel device independent quantum key distribution (DIQKD) protocol based on the CHSH game and prove its security. Using techniques developed for analysing the paral…
Universal chain rules from entropic triangle inequalities
Ashutosh Marwah, Frédéric Dupuis
The von Neumann entropy of an -partite system given a system can be written as the sum of the von Neumann entropies of the individual subsystems given $A_1^{k-…
Proving security of BB84 under source correlations
Ashutosh Marwah, Frédéric Dupuis
Device imperfections and memory effects can result in undesired correlations among the states generated by a realistic quantum source. These correlations are called source correlat…
Smooth min-entropy lower bounds for approximation chains
Ashutosh Marwah, Frédéric Dupuis
For a state , we call a sequence of states an approximation chain if for every , $ρ_{A_1^k B} \approx_εσ_{A_1^k B}^{(k)}…
Uniform continuity bound for sandwiched Rényi conditional entropy
Ashutosh Marwah, Frédéric Dupuis
We prove a simple uniform continuity bound for the sandwiched Rényi conditional entropy for , which is independent of the dimension of the condition…
Optical quantum communication complexity in the simultaneous message passing model
Ashutosh Marwah, Dave Touchette
The communication cost of a classical protocol is typically measured in terms of the number of bits communicated for this determines the time required for communication during the…
