 Matched filtering is a signal processing technique used to maximize the signal-to-noise ratio by correlating signal templates with detector data. It is central for detecting the extraordinarily weak signals in the field of gravitational wave astronomy. In cases where the signal is too weak and the template bank is too extensive, the matched filtering process can become computationally unfeasible. Quantum computational devices, currently under development, offer the potential to speed up some computational tasks, compared to what is possible classically. In this talk I will discuss work with colleagues in the Institute for Gravitational Research, proposing the use of Grover’s algorithm, one of the earliest suggested quantum algorithms, to speed up match filtering for gravitational wave detection (https://arxiv.org/abs/2109.01535
