First-order and interior-point methods for entanglement detection
Javier Pena, Vikesh Siddhu, Sridhar Tayur
Quantum entanglement lies at the heart of quantum information science, yet its reliable detection in high-dimensional or noisy systems remains a fundamental computational challenge…
Sequential vs. Simultaneous Entanglement Swapping under Optimal Link-Layer Control
Priyam Srivastava, Akshat R. Sabavat, Siddharth Jain +6
Connection-less, packet-switched quantum network architectures distribute entanglement across multi-hop paths through sequential entanglement swapping, in which each node acts on p…
Spontaneous Decoherence from Logarithmic Spectral Phase Deformations
Sridhar Tayur
We examine a mechanism of spontaneous decoherence in which the generator of quantum dynamics is deformed to a logarithmically modified self-adjoint operator \begin{equation*} F_β(…
Five Starter Problems: Solving Quadratic Unconstrained Binary Optimization Models on Quantum Computers
Arul Mazumder, Sridhar Tayur
This tutorial offers a quick, hands-on introduction to solving Quadratic Unconstrained Binary Optimization (QUBO) models on currently available quantum computers and their simulato…
