Constraints on Gaussian Error Channels and Measurements for Quantum Communication
Alex Kwiatkowski, Ezad Shojaee, Sristy Agrawal +4
Joint Gaussian measurements of two quantum systems can be used for quantum communication between remote parties, as in teleportation or entanglement swapping protocols. Many types…
Better transmission with lower capacity: lossy compression over quantum channels
Sristy Agrawal, Rajashik Tarafder, Graeme Smith +2
Shannon's channel coding theorem describes the maximum possible rate of reliable information transfer through a classical noisy communication channel. It, together with the source…
The principle of information symmetry constrains the state-space in any physical theory
Manik Banik, Sutapa Saha, Tamal Guha +4
Symmetry shares an entwined history with the structure of physical theory. We propose a consequence of symmetry towards the axiomatic derivation of Hilbert space quantum theory. We…
Indefinite causal order enables perfect quantum communication with zero capacity channels
Giulio Chiribella, Manik Banik, Some Sankar Bhattacharya +6
Quantum mechanics is compatible with scenarios where the relative order between two events can be indefinite. Here we show that two independent instances of a noisy process can beh…
Genuinely entangled subspace with all-encompassing distillable entanglement across every bipartition
Sristy Agrawal, Saronath Halder, Manik Banik
In a multipartite scenario quantum entanglement manifests its most dramatic form when the state is genuinely entangled. Such a state is more beneficial for information theoretic ap…
Strong Quantum Nonlocality without Entanglement
Saronath Halder, Manik Banik, Sristy Agrawal +1
Quantum nonlocality is usually associated with entangled states by their violations of Bell-type inequalities. However, even unentangled systems, whose parts may have been prepared…
