Characterizing pairwise swapping capabilities of dense coding channels
Abhishek Muhuri, Nirman Ganguly, Aditi Sen De +1
We introduce a novel multipartite entanglement-assisted classical communication task, referred to as dense coding swapping, in which legitimate parties collaboratively swap the den…
Enhancing the teleportation fidelity of a quantum network using purification
Soumit Roy, Md Sohel Mondal, Siddhartha Santra +1
Complex quantum networks can support a diverse set of long-range entanglement distribution schemes ranging from linear repeater protocols to multipath entanglement purification str…
Revocation and Reconstruction of Shared Quantum States
Prakash Mudholkar, Chiranjeevi Vanarasa, Indranil Chakrabarty +1
The problem of revocation of quantum states after sharing is interesting and we ask: Is it possible for a dealer to revoke the state once shared, before the reconstruction process?…
Teleportation Fidelity of Binary Tree Quantum Repeater Networks
Soumit Roy, Md Rahil Miraj, Chittaranjan Hens +3
Binary tree network, being a subclass of Cayley tree network, is a significant topological structure used for information transfer in a hierarchical sense. In this article, we cons…
Secure and Efficient Quantum Signature Scheme Based on the Controlled Unitary Operations Encryption
Debnath Ghosh, Soumit Roy, Prithwi Bagchi +2
Quantum digital signatures ensure unforgeable message authenticity and integrity using quantum principles, offering unconditional security against both classical and quantum attack…
Teleportation fidelity of quantum repeater networks
Ganesh Mylavarapu, Subrata Ghosh, Chittaranjan Hens +2
We show that the average of the maximum teleportation fidelities between all pairs of nodes in a large quantum repeater network is a measure of the resourcefulness of the network a…
On fully entangled fraction and quantum conditional entropies for states with maximally mixed marginals
Komal Kumar, Indranil Chakrabarty, Nirman Ganguly
The fully entangled fraction (FEF) measures the proximity of a quantum state to maximally entangled states. FEF , in systems is a significant benchmark…
Maximal Secret Reconstruction, Teleportation and Bell's Inequality
Pratishtha Abrol, Pahulpreet Singh, Indranil Chakrabarty
A tripartite state is said to be a potential resource for secret sharing if the state imposes restrictions on the teleportation fidelity of the bipartite dealer--reconstructor and…
Using Quantum Switches to Mitigate Noise in Grover's Search Algorithm
Suryansh Srivastava, Arun K. Pati, Samyadeb Bhattacharya +1
Grover's quantum search algorithm promises a quadratic speedup for unstructured search over its classical counterpart. But this advantage is affected by noise acting on the search…
Quantum channels that destroy negative conditional entropy
PV Srinidhi, Indranil Chakrabarty, Samyadeb Bhattacharya +1
Counter-intuitive to classical notions, quantum conditional entropy can be negative, playing a pivotal role in information-processing tasks. This article delves deeply into quantum…
Breaking absolute separability with quantum switch
Sravani Yanamandra, P V Srinidhi, Samyadeb Bhattacharya +2
Absolute separable (AS) quantum states are those states from which it is impossible to create entanglement, even under global unitary operations. It is known from the resource theo…
Revocation and Reconstruction of Shared Quantum States
Prakash Mudholkar, Chiranjeevi Vanarasa, Indranil Chakrabarty +1
The problem of revocation of quantum states after sharing is interesting and we ask: Is it possible for a dealer to revoke the state once shared, before the reconstruction process?…
Complementarity between Tripartite Quantum Correlation and Bipartite Bell Inequality Violation in Three Qubit States
Palash Pandya, Avijit Misra, Indranil Chakrabarty
We find a single parameter family of genuinely entangled three qubit pure states, called the maximally Bell inequality violating states (MBV), which exhibit maximum Bell inequality…
