Quantum Information-Theoretic Analysis of Optical Fiber Sensing via Stimulated Brillouin Scattering
Kiran Adhikari, Janis Nötzel
Stimulated Brillouin scattering (SBS) is a powerful mechanism for distributed sensing in optical fibers, as the Brillouin response is highly sensitive to local material parameters.…
Certified Fidelity Susceptibility from Classical Shadows
Kiran Adhikari
Fidelity susceptibility is a useful probe of quantum phase transitions and quantum metrology, but its direct evaluation on a quantum device is challenging. By integrating Krylov-su…
Quantum-Limited Blind Source Separation of Classical Light
Janis Nötzel, Kiran Adhikari
Using the framework of quantum multiparameter estimation, we study the problem of separating independent thermal optical sources mixed by an unknown passive linear transformation,…
Fundamental Limits of Eavesdropper Detection and Localization in Optical Fiber via Stimulated Brillouin Scattering
Kiran Adhikari, Janis Nötzel
Recent work investigated the use of Stimulated Brillouin Scattering (SBS) to measure changes in fiber parameters, thereby enhancing the security of a Quantum Key Distribution (QKD)…
Quantum ramp secret sharing from Haar scrambling
Kiran Adhikari
Quantum information scrambling has emerged as a powerful tool for studying the dynamics of chaotic quantum many-body systems, assessing benchmarking protocols, and even investigati…
Krylov Polynomials and Quantum Query Complexity
Kiran Adhikari
We show that the minimal query complexity for preparing is exactly the optimal polynomial approximation degree of in , where is the spectral measure…
Quantum optimization of coherent chaotic systems: A case for buses of Kathmandu
Kiran Adhikari, Aman Ganeju, Iva Kumari Lamichhane +4
In this paper, we propose a novel quantum computing approach to solve the real-world problem of optimizing transportation in bustling Kathmandu city. The transportation system in K…
Quantum information spreading and scrambling in a distributed quantum network: A Hasse/Lamport diagrammatic approach
Kiran Adhikari, Christian Deppe
Large-scale quantum networks, known as quantum internet, hold great promises for advanced distributed quantum computing and long-distance quantum communication. It is essential to…
Krylov Complexity of Fermionic and Bosonic Gaussian States
Kiran Adhikari, Adwait Rijal, Ashok Kumar Aryal +3
The concept of \emph{complexity} has become pivotal in multiple disciplines, including quantum information, where it serves as an alternative metric for gauging the chaotic evoluti…
