The wave-function is real but nonphysical: A view from counterfactual quantum cryptography

Akshata Shenoy H., R. Srikanth

Counterfactual quantum cryptography (CQC) is used here as a tool to assess the status of the quantum state: Is it real/ontic (an objective state of Nature) or epistemic (a state of…

Exploring the role of Leggett-Garg inequality for quantum cryptography

Akshata Shenoy H., S. Aravinda, R. Srikanth +1

In the cryptographic context, an earlier unexplored application of the temporal version of the Bell-type inequality is shown here in the device-independent (DI) scenario. This is d…

Quantum criticality of geometric phase in coupled optical cavity arrays under linear quench

Sujit Sarkar

The atoms trapped in microcavities and interacting through the exchange of virtual photons can be modeled as an anisotropic Heisenberg spin-1/2 lattice. We study the dynamics of th…

Emergent of Majorana Fermion mode and Dirac Equation in Cavity Quantum Electrodynamics

Sujit Sarkar

We present the results of low lying excitation of coupled optical cavity arrays. We derive the Dirac equation for this system and explain the existence of Majorana fermion mode in…

Violation of no signaling in higher order quantum measure theories

Karthik S. Joshi, R. Srikanth, Urbasi Sinha

More general probability sum-rules for describing interference than found in quantum mechanics (QM) were formulated by Sorkin in a hierarchy of such rules. The additivity of classi…

Unification of Bell, Leggett-Garg and Kochen-Specker inequalities: A hybrid spatio-temporal inequality

Siddhartha Das, S. Aravinda, R. Srikanth +1

The Bell-type (spatial), Kochen-Specker (contextuality) or Leggett-Garg (temporal) inequalities are based on classically plausible but otherwise quite distinct assumptions. For any…

Semi-counterfactual Cryptography

Akshata Shenoy H., R. Srikanth, T. Srinivas

In counterfactual quantum key distribution (QKD), two remote parties can securely share random polarization-encoded bits through the blocking rather than the transmission of partic…
