Local cloning of genuine entangled states of three qubit
Sujit K. Choudhary, Guruprasad Kar, Samir Kunkri +2
We discuss (im)possibility of the exact cloning of orthogonal but genuinely entangled three qubit states aided with entangled ancila under local operation and classical communicati…
Local Cloning of Entangled Qubits
Sujit K. Choudhary, Samir Kunkri, Ramij Rahaman +1
We discuss the exact cloning of orthogonal but entangled qubits under local operations and classical communication. The amount of entanglement necessary in blank copy is obtained f…
Causality, Joint measurement and Tsirelson's bound
Sujit K. Choudhary, Guruprasad Kar, Samir Kunkri +1
Tsirelson showed that is the maximum value that CHSH expression can take for quantum-correlations [B. S.Tsirelson, Lett. Math. Phys, 4 (1980) 93]. This bound simply fol…
Nonlocality without inequality for almost all two-qubit entangled state based on Cabello's nonlocality argument
Samir Kunkri, Sujit K. Choudhary, Ali Ahanj +1
Here we deal with a nonlocality argument proposed by Cabello which is more general than Hardy's nonlocality argument but still maximally entangled states do not respond. However, f…
No-Flipping as a consequence of No-Signalling and Non-increase of Entanglement under LOCC
Indrani Chattopadhyay, Sujit K. Choudhary, Guruprasad Kar +2
Non existence of Universal NOT gate for arbitrary quantum mechanical states is a fundamental constraint on the allowed operations performed on physical systems. The largest set of…
Nonlocality without inequality for spin-s system
Samir Kunkri, Sujit K. Choudhary
We analyze Hardy's non-locality argument for two spin-s systems and show that earlier solution in this regard was restricted due to imposition of some conditions which have no role…
