Abstract
Recorded 25 January 2022. Jarrod McClean of Google presents "Dequantization and quantum advantage in learning from experiments" at IPAM's Quantum Numerical Linear Algebra Workshop. Abstract: Quantum technology has the potential to revolutionize how we acquire and process experimental data to learn about the physical world. An experimental setup that transduces data from a physical system to a stable quantum memory, and processes that data using a quantum computer, could have significant advantages over conventional experiments in which the physical system is measured and the outcomes are processed using a classical computer. We prove that, in various tasks, quantum machines can learn from exponentially fewer experiments than those required in conventional experiments. The exponential advantage holds in predicting properties of physical systems, performing quantum principal component analysis on noisy states, and learning approximate models of physical dynamics. As a note related to quantum linear algebra, we explore recent dequantization results in a different context and discuss the nuances related to dequantization of quantum algorithms.
