Security Proof for Variable-Length Quantum Key Distribution
Devashish Tupkary, Ernest Y. -Z. Tan, Norbert Lütkenhaus
We present a security proof for variable-length QKD in the Renner framework against IID collective attacks. Our proof can be lifted to coherent attacks using the postselection tech…
Using Cascade in Quantum Key Distribution
Devashish Tupkary, Norbert Lütkenhaus
We point out a critical flaw in the analysis of Quantum Key Distribution (QKD) protocols that employ the two-way error correction protocol Cascade. Specifically, this flaw stems fr…
Searching for Lindbladians obeying local conservation laws and showing thermalization
Devashish Tupkary, Abhishek Dhar, Manas Kulkarni +1
We investigate the possibility of a Markovian quantum master equation (QME) that consistently describes a finite-dimensional system, a part of which is weakly coupled to a thermal…
