Save Big on Coursera Plus. 7,000+ courses at $160 off. Limited Time Only! Grab it Explore a 47-minute seminar presentation that delves into an innovative quantum state tomography protocol capable of handling systems beyond ten qubits. Learn about a groundbreaking method that requires only 2n + 1 quantum circuits for n-qubit systems, featuring single Pauli gates per qubit during measurement. Discover how this protocol addresses the exponential scaling challenges in quantum computer state reconstruction, including circuit requirements, non-local gates, and postprocessing time. Examine the protocol's successful implementation on IBM quantum computers, achieving high fidelities for genuinely entangled states up to 10 qubits, and understand its significance in advancing quantum computing capabilities during the NISQ era. Follow along as the speaker presents experimental results and discusses the protocol's advantages, including its explicit reconstruction formula and elimination of postprocessing requirements for quantum state estimation.
