Certifying Almost All Quantum States with Few Single-Qubit Measurements

Join a quantum seminar exploring groundbreaking research on certifying n-qubit states using minimal single-qubit measurements. Learn about a novel protocol that requires only O(n^2) single-qubit measurements to certify almost all n-qubit target states, including those with exponential circuit complexity. Discover how this innovative technique connects certification to random walk mixing time, offering practical applications in quantum system benchmarking, quantum circuit optimization, and learning various quantum state representations. Examine the protocol's implications for predicting non-local properties efficiently and its demonstrated advantages over existing methods like cross-entropy benchmarking (XEB) in experiments with up to 120 qubits. Led by Dr. Hsin-Yuan Huang, a distinguished Senior Research Scientist at Google Quantum AI and future Assistant Professor at Caltech, whose groundbreaking work in quantum learning theory has been published in prestigious journals and earned numerous accolades, including the Milton and Francis Clauser Doctoral Prize.
