A Secure Quantum Key Distribution Protocol Using Two-Particle Transmission
Pratapaditya Bej, Vinod Jayakeerthi
The evolution of Quantum Key Distribution (QKD) relies on innovative methods to enhance its security and efficiency. Unextendible Product Bases (UPBs) hold promise in quantum crypt…
Activation of entanglement in generalized entanglement swapping
Pratapaditya Bej, Abhishek Banerjee
We study entanglement activation in a generalized entanglement swapping process involving two Bell pairs and generalized measurements. The conventional understanding posits entangl…
When Mei-Gu Guan's 1960 Postmen Get Empowered with Bell's 1964 Nonlocal Correlations, or, Nonlocal Advantage in Vehicle Routing Problem
Abhishek Banerjee, Pratapaditya Bej, Amit Mukherjee +3
Vehicle routing problems, a comprehensive problem category originated from the seminal Chinese Postman Problem (first investigated by Chinese mathematician Mei-Gu Guan), entail str…
Quantum change point and entanglement distillation
Abhishek Banerjee, Pratapaditya Bej, Somshubhro Bandyopadhyay
In a quantum change point problem, a source emitting particles in a fixed quantum state (default) switches to a different state at some stage, and the objective is to identify when…
Braess Paradox in a quantum network
Abhishek Banerjee, Pratapaditya Bej
Dietrich Braess while working on traffic modelling, noticed that traffic flow in a network can be worsened by adding extra edges to an existing network. This seemingly counterintui…
Creating quantum correlations in generalized entanglement swapping
Pratapaditya Bej, Arkaprabha Ghosal, Arup Roy +2
We study how different types of quantum correlations can be established as the consequence of a generalized entanglement swapping protocol where starting from two Bell pairs (1, 2)…
