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…
Quantum nonlocality without entanglement and state discrimination measures
Shayeef Murshid, Tathagata Gupta, Vincent Russo +1
An ensemble of product states is said to exhibit "quantum nonlocality without entanglement" if it cannot be optimally discriminated using local operations and classical communicati…
Gottesman-Knill Limit on One-way Communication Complexity: Tracing the Quantum Advantage down to Magic Resources
Snehasish Roy Chowdhury, Sahil Gopalkrishna Naik, Ananya Chakraborty +5
Quantum systems are known to offer advantages over their classical counterpart in communication complexity protocols, where the aim is to minimize the amount of information exchang…
Landauer Principle and Thermodynamics of Computation
Pritam Chattopadhyay, Avijit Misra, Tanmoy Pandit +1
According to the Landauer principle, any logically irreversible process accompanies entropy production, which results in heat dissipation in the environment. Erasing of information…
Generalization Bounds for Quantum Learning via Rényi Divergences
Naqueeb Ahmad Warsi, Ayanava Dasgupta, Masahito Hayashi
This work advances the theoretical understanding of quantum learning by establishing a new family of upper bounds on the expected generalization error of quantum learning algorithm…
Efficient and high-fidelity entanglement in cavity QED without high cooperativity
Sumit Goswami, Cheng-Hsuan Chien, Neil Sinclair +4
The so-called state-carving protocol generates high-fidelity entangled states at an atom-cavity interface without requiring high cavity cooperativity. However, this protocol is lim…
