Hierarchy of quantum correlations in qubit-qutrit axially symmetric states
Venkat Abhignan, R. Muthuganesan
We investigate quantum correlations in a hybrid qubit-qutrit system subject to both axial and planar single-ion anisotropies, dipolar spin-spin interactions, and Dzyaloshinskii-Mor…
Increasing the secret key rates and point-to-multipoint extension for experimental coherent-one-way quantum key distribution protocol
Venkat Abhignan, Mohit Mittal, Aditi Das +1
Using quantum key distribution (QKD) protocols, a secret key is created between two distant users (transmitter and receiver) at a particular key rate. Quantum technology can facili…
Effect of Weak Measurement Reversal on Quantum Correlations in a Correlated Amplitude Damping Channel, with a Neural Network Perspective
Venkat Abhignan, Bidyut Bikash Boruah, R. Srikanth +1
We study the evolution of quantum correlations in Bell, Werner, and maximally entangled mixed states of two qubits subjected to correlated amplitude-damping channels. Our primary f…
Quasiperiodic arrangement of magnetodielectric -plates: Green's functions and Casimir energies for bodies
Venkat Abhignan
We study a variety of finite quasiperiodic configurations with magnetodielectric -function plates created from simple substitution rules. While previous studies for bodies i…
Randomness in quantum random number generator from vacuum fluctuations with source-device-independence
Megha Shrivastava, Mohit Mittal, Isha Kumari +1
The application for random numbers is ubiquitous. We experimentally build a well-studied quantum random number generator from homodyne measurements on the quadrature of the vacuum…
Simulations of distributed-phase-reference quantum key distribution protocols
Venkat Abhignan, Abhishek Jamunkar, Gokul Nair +2
Quantum technology can enable secure communication for cryptography purposes using quantum key distribution. Quantum key distribution protocols provide a secret key between two use…
Casimir energy for constant conductivity -plates with a neural network perception
Venkat Abhignan
The Casimir energy for -function plates depends on the multiple scattering parameter . This -body interaction was distributed into interactions with nearest neighbour…
Device-Independent Quantum Secure Direct Communication Under Non-Markovian Quantum Channels
Pritam Roy, Subhankar Bera, Shashank Gupta +1
Device-independent quantum secure direct communication (DI-QSDC) is a promising primitive in quantum cryptography aimed towards addressing the problems of device imperfections and…
Genuine three qubit Einstein-Podolsky-Rosen steering under decoherence: Revealing hidden genuine steerability via pre-processing
Shashank Gupta
The behaviour of genuine EPR steering of three qubit states under various environmental noises is investigated. In particular, we consider the two possible steering scenarios in th…
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…
A MATLAB based modeling and simulation package for DPS-QKD
Anuj Sethia, Anindita Banerjee
Quantum key distribution (QKD) is an ingenious technology utilizing quantum information science for provable secure communication. However, owing to the technological limitations a…
