Dimensional advantage in secure information trading via the noisy dense coding protocol
Ayan Patra, Rivu Gupta, Tamoghna Das +1
The quantum dense coding (DC) protocol, which has no security feature, deals with the transmission of classical information encoded in a quantum state by using shared entanglement…
Information theoretic resource-breaking channels
Abhishek Muhuri, Ayan Patra, Rivu Gupta +1
We propose the notion of process resource-breaking channels that break the resource for a quantum information processing task. We examine the same using quantum dense coding and te…
Entangled universes in dS wedge holography
Sergio E. Aguilar-Gutierrez, Ayan K. Patra, Juan F. Pedraza
We develop a new setting in the framework of braneworld holography to describe a pair of coupled and entangled uniformly accelerated universes. The model consists of two branes emb…
Perfect transfer of arbitrary continuous variable states across optical waveguide lattices
Tonipe Anuradha, Ayan Patra, Rivu Gupta +1
We demonstrate that perfect state transfer can be achieved in an optical waveguide lattice governed by a Hamiltonian with modulated nearest-neighbor couplings. In particular, we re…
Holographic complexity of Jackiw-Teitelboim gravity from Karch-Randall braneworld
Aranya Bhattacharya, Arpan Bhattacharyya, Ayan K. Patra
Recently, it has been argued in [1] that Jackiw-Teitelboim (JT) gravity can be naturally realized in the Karch-Randall braneworld in dimensions. Using the `complexity=volum…
Production of genuine multimode entanglement in circular waveguides with long-range interactions
T Anuradha, Ayan Patra, Rivu Gupta +2
Starting with a product initial state, squeezed (squeezed coherent) state in one of the modes, and vacuum in the rest, we report that a circular waveguide comprising modes coupled…
