Wigner's Friend - The Measurement Problem with Quantum Circuits - Episode 2

Explore the fascinating measurement problem in quantum mechanics through a 12-minute educational video where Oxford PhD researcher Maria Violaris breaks down Wigner's friend paradox using quantum circuits. Discover how an observer measuring another observer who measures a qubit creates a contradiction in the Copenhagen interpretation of quantum mechanics. Learn to simulate this paradox by coding quantum circuits with Qiskit, with access to complete code examples via a provided Jupyter Notebook. Gain practical insights into quantum computing concepts while understanding how this thought experiment challenges our understanding of quantum measurement. Build upon previous knowledge from the Schrödinger's Cat episode and connect to broader quantum information concepts through the recommended Understanding Quantum Information and Computation lecture series.
