Standard Quantum Teleportation of an Arbitrary N-Qubit State, Non-Existence of Magic Basis and Existence of Magic Partial Bases for 2N Entangled Qubit States with N>1
Hari Prakash, Vikram Verma
We present a simple and precise protocol for standard quantum teleportation of N-qubit state, considering the most general resource q-channel and Bell states. We find condition on…
Two-Way Quantum Communication: `Secure Quantum Information Exchange'-II. Generalization to Arbitrary Number of Qubits
Ajay K Maurya, Manoj K Mishra, Hari Prakash
In this paper, we generalize the secure quantum information exchange (SQIE) protocol, originally proposed by the authors [J. Phys. B: At. Mol. Opt. Phys. 44 (2011) 115504] for secu…
Increasing Average Fidelity by Using Non-Maximally Entangled Resource in Teleportation of Superposed Coherent States
Hari Prakash, Manoj K Mishra
We consider the problem of teleporting superposed coherent state using non-maximally entangled coherent state as quantum channel and study the effect of entanglement over quality o…
Higher-order optical-polarization
Ravi S. Singh, Hari Prakash
Polarization properties of optical field in Schrödinger Cat states or Even- or Odd-Coherent states are investigated by generalizing usual concept of optical-polarization to render…
