Hadamard type operations for qubits
Arpita Maitra, Preeti Parashar
We obtain the most general ensemble of qubits, for which it is possible to design a universal Hadamard gate. These states when geometrically represented on the Bloch sphere, give a…

Exact remote state preparation for multiparties
P. Agrawal, P. Parashar, A. K. Pati
We discuss the exact remote state preparation protocol of special ensembles of qubits at multiple locations. We also present generalization of this protocol for higher dimensional…
