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?…
Thermodynamic work capacity of quantum information processing
Himanshu Badhani, Dhanuja G S, Siddhartha Das
We introduce the resource-theoretic free energy of a quantum channel as the maximal work extractable from the channel as its output equilibrates to a thermal state and its referenc…
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…
Fast computational deep thermalization
Shantanav Chakraborty, Soonwon Choi, Soumik Ghosh +1
Deep thermalization refers to the emergence of Haar-like randomness from quantum systems upon partial measurements. As a generalization of quantum thermalization, it is often assoc…
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…
Maximum entropy principle for quantum processes
Siddhartha Das, Ujjwal Sen
The maximum entropy principle, as applied to quantum systems, is a fundamental prescript positing that for a quantum system for which we only have partial knowledge, the maximum en…
Limits of Classical correlations and Quantum advantages under (Anti-)Distinguishability constraints in Multipartite Communication
Ankush Pandit, Soumyabrata Hazra, Satyaki Manna +2
We consider communication scenarios with multiple senders and a single receiver. Focusing on communication tasks where the distinguishability or antidistinguishability of the sende…
Erasure cost of a quantum process: A thermodynamic meaning of the dynamical min-entropy
Himanshu Badhani, Dhanuja GS, Swati Choudhary +2
The erasure of information is fundamentally an irreversible logical operation, carrying profound consequences for the energetics of computation and information processing. We inves…
Security of deterministic key distribution with higher-dimensional systems
Abhishek Muhuri, Ayan Patra, Rivu Gupta +2
We analyze the security of two-way quantum key distribution using arbitrary finite-dimensional systems, considering both individual and collective eavesdropping attacks, without th…
Simulating quantum collision models with Hamiltonian simulations using early fault-tolerant quantum computers
Kushagra Garg, Zeeshan Ahmed, Subhadip Mitra +1
We develop randomized quantum algorithms to simulate quantum collision models, also known as repeated interaction schemes, which provide a rich framework to model various open-syst…
