Geometric bounds on multiparameter Heisenberg scaling in optical metrology with limited squeezed resources
Atmadev Rai, Paolo Facchi, Vincenzo Tamma
The simultaneous estimation of multiple parameters is a central task in quantum metrology, distributed sensing, and the calibration of large photonic interferometers. A fundamental…

Multiparameter quantum metrology at Heisenberg scaling for an arbitrary two-channel linear interferometer with squeezed light
Atmadev Rai, Danilo Triggiani, Paolo Facchi +1
We present a framework for simultaneously estimating all four real parameters of a general two-channel unitary U(2) with Heisenberg-scaling precision. We derive analytical expressi…

Experimental realization of quantum teleportation of arbitrary single and two-qubit states via hypergraph states
Atmadev Rai, Bikash K. Behera
Here we demonstrate quantum teleportation through hypergraph states, which are the generalization of graph states, and due to their non-local entanglement properties, it allows us…
