Signatures of chaos in the dynamics of quantum discord
Vaibhav Madhok, Vibhu Gupta, Angele M. Hamel +1
We identify signatures of chaos in the dynamics of discord in a multiqubit system collectively modelled as a quantum kicked top. The evolution of discord between any two qubits is…

Multiparty quantum communication using multiqubit entanglement and teleportation
Shohini Ghose, Atul Kumar, Vaibhav Madhok +1
We propose a 2N qubit entangled channel that can be used to teleport N qubits in a network to a single receiver. We describe the construction of this channel and explicitly demonst…

Information gain in tomography - A quantum signature of chaos
Vaibhav Madhok, Carlos A. Riofrío, Shohini Ghose +1
We find quantum signatures of classical chaos in various metrics of information gain in quantum tomography. We employ a quantum state estimator based on weak collective measurement…
