A universal whitening algorithm for commercial random number generators
Avval Amil, Shashank Gupta
Random number generators are imperfect due to manufacturing bias and technological imperfections. These imperfections are removed using post-processing algorithms that in general c…
Quantum entropy expansion using n-qubit permutation matrices in Galois field
Avval Amil, Shashank Gupta
Random numbers are critical for any cryptographic application. However, the data that is flowing through the internet is not secure because of entropy deprived pseudo random number…
Device-Independent Quantum Key Distribution Using Random Quantum States
Subhankar Bera, Shashank Gupta, A. S. Majumdar
We Haar uniformly generate random states of various ranks and study their performance in an entanglement-based quantum key distribution (QKD) task. In particular, we analyze the ef…
Quantum contextuality provides communication complexity advantage
Shashank Gupta, Debashis Saha, Zhen-Peng Xu +2
Despite the conceptual importance of contextuality in quantum mechanics, there is a hitherto limited number of applications requiring contextuality but not entanglement. Here, we s…
