Catalytic Transformations of Pure Entangled States
Tulja Varun Kondra, Chandan Datta, Alexander Streltsov
Quantum entanglement of pure states is usually quantified via the entanglement entropy, the von Neumann entropy of the reduced state. Entanglement entropy is closely related to ent…
Perfect discrimination of quantum measurements using entangled systems
Chandan Datta, Tanmoy Biswas, Debashis Saha +1
Distinguishing physical processes is one of the fundamental problems in quantum physics. Although distinguishability of quantum preparations and quantum channels have been studied…
Sub-Rayleigh resolution of two incoherent sources by array homodyning
Chandan Datta, Marcin Jarzyna, Yink Loong Len +3
Conventional incoherent imaging based on measuring the spatial intensity distribution in the image plane faces the resolution hurdle described by the Rayleigh diffraction criterion…
Resolution limits of spatial mode demultiplexing with noisy detection
Yink Loong Len, Chandan Datta, Michał Parniak +1
We consider the problem of estimating the spatial separation between two mutually incoherent point light sources using the super-resolution imaging technique based on spatial mode…
Two-qubit mixed states and teleportation fidelity: Purity, concurrence, and beyond
Sumit Nandi, Chandan Datta, Arpan Das +1
To explore the properties of a two-qubit mixed state, we consider quantum teleportation. The fidelity of a teleported state depends on the resource state purity and entanglement, a…
Can Quantum discord increase in a quantum communication task?
Shubhayan Sarkar, Chandan Datta
Quantum teleportation of an unknown quantum state is one of the few communication tasks which has no classical counterpart. Usually the aim of teleportation is to send an unknown q…
