An explicit scheme (quantum circuit) is designed for the teleportation of an n-qubit quantum state. It is established that the proposed scheme requires an optimal amount of quantum resources, whereas larger amount of quantum resources has been used in a large number of recently reported teleportation schemes for the quantum states which can be viewed as(More)
Recently, several aspects of controlled quantum communication (e.g., bidirectional controlled state teleportation, controlled quantum secure direct communication, controlled quantum dialogue, etc.) have been studied using n-qubit (n ≥ 3) entanglement. Specially, a large number of schemes for bidirectional controlled state teleportation are proposed using(More)
In secure quantum communication protocols, a set of single qubits prepared using 2 or more mutually unbiased bases or a set of n-qubit (n ≥ 2) entangled states of a particular form are usually used to form a verification string which is subsequently used to detect traces of eavesdropping. The qubits that form a verification string are referred to as decoy(More)
The structure of 3-(4-bromophenyl)-5-phenyl-4,5-dihydro-1H-pyrazole-1-carbaldehyde was determined by using X-ray diffraction analysis. Photophysical studies of the title compound were investigated in the solvents with different polarities. The emission spectrum of the compound was recorded in polar solvent DMSO (356 nm). In different solvents the extinction(More)
