Linear and nonlinear quantum Zeno and anti-Zeno effects in a nonlinear optical coupler
Kishore Thapliyal, Anirban Pathak, Jan Perina
Quantum Zeno and anti-Zeno effects are studied in a symmetric nonlinear optical coupler, which is composed of two nonlinear () waveguides that are interacting w…
Higher order two-mode and multi-mode entanglement in Raman processes
Sandip Kumar Giri, Biswajit Sen, Anirban Pathak +1
The existence of higher order entanglement in the stimulated and spontaneous Raman processes is established using the perturbative solutions of the Heisenberg equations of motion f…
Which verification qubits perform best for secure communication in noisy channel?
Rishi Dutt Sharma, Kishore Thapliyal, Anirban Pathak +2
In secure quantum communication protocols, a set of single qubits prepared using 2 or more mutually unbiased bases or a set of -qubit () entangled states of a particular…
Quantum Zeno and anti-Zeno effects in an asymmetric nonlinear optical coupler
Kishore Thapliyal, Anirban Pathak
Quantum Zeno and anti-Zeno effects in an asymmetric nonlinear optical coupler are studied. The asymmetric nonlinear optical coupler is composed of a linear waveguide ($χ^{\left(1\r…
Tomograms for open quantum systems: in(finite) dimensional optical and spin systems
Kishore Thapliyal, Subhashish Banerjee, Anirban Pathak
Tomograms are obtained as probability distributions and are used to reconstruct a quantum state from experimentally measured values. We study the evolution of tomograms for differe…
A General Method for Selecting Quantum Channel for Bidirectional Controlled State Teleportation and Other Schemes of Controlled Quantum Communication
Kishore Thapliyal, Amit Verma, Anirban Pathak
Recently, a large number of protocols for bidirectional controlled state teleportation (BCST) have been proposed using -qubit entangled states () as quantum chann…
