Protocols for counterfactual and twin-field quantum digital signature
Vinod N. Rao, Shrikant Utagi, Anirban Pathak +1
Quantum digital signature (QDS) is the quantum version of its classical counterpart, and can offer security against attacks of repudiation, signature forging and external eavesdrop…
Quantum counterfactuality with identical particles
Vinod N. Rao, Anindita Banerjee, R. Srikanth
Quantum self-interference enables the counterfactual transmission of information, whereby the transmitted bits involve no particles traveling through the channel. In this work, we…
Noiseless attack and counterfactual security of quantum key distribution
Vinod N. Rao, R. Srikanth
Counterfactual quantum key distribution (QKD) enables two parties to share a secret key using an interaction-free measurement. Here, we point out that the efficiency of counterfact…
Singularities, mixing and non-Markovianity of Pauli dynamical maps
Shrikant Utagi, Vinod N. Rao, R. Srikanth +1
Quantum non-Markovianity of channels can be produced by mixing Markovian channels, as observed recently by various authors. We consider an analogous question of whether singulariti…
A class of quasi-eternal non-Markovian Pauli channels and their measure
Shrikant Utagi, Vinod N. Rao, R. Srikanth +1
We study a class of qubit non-Markovian general Pauli dynamical maps with multiple singularities in the generator. We discuss a few easy examples involving trigonometric or other n…
