🧪 Speaker: Prof. A. R. Usha Devi, Senior Professor, Bangalore University
📌 Topic: Quantum State Tomography of Three-Qubit States & Reconstruction of Pure Three-Qubit W State
🎥 Workshop: Symposium on AI & Quantum Computing
About the Talk:
In this insightful lecture, Prof. A. R. Usha Devi presents a novel quantum state tomography approach to reconstruct arbitrary three-qubit states with just 17 measurements, a significant reduction from the standard 64 Pauli measurements. Key topics covered include:
✔️ Efficient Quantum State Tomography Methods
✔️ Geometric Visualization of Two-Qubit Reduced States
✔️ SL(2,C) Invariants in Quantum Information
✔️ Reconstruction of a Whole 3-Qubit State from 2-Qubit Reduced Density Matrices
✔️ Experimental Implementation on IBM's 127-Qubit Quantum Processor (ibm_osaka)
The session delves into groundbreaking methodologies for reconstructing multi-qubit states and presents a geometric embedding of quantum data using ellipsoids within the Bloch sphere.
