A new method of identifying gravitational wave signals using quantum computing could provide a valuable new tool for future astrophysicists.
Grover's algorithm, developed by computer scientist Lov Grover in 1996, harnesses the unusual capabilities and applications of quantum theory to make the process of searching through databases much faster.
The Glasgow team are the first to adapt Grover's algorithm for the purposes of gravitational wave search. In the paper, they demonstrate how they have applied it to gravitational wave searches through software they developed using the Python programming language and Qiskit, a tool for simulating quantum computing processes.
Dr. Scarlett Gao, from the University's School of Physics & Astronomy, is one of the lead authors of the paper. Dr. Gao said:"Matched filtering is a problem that Grover's algorithm seems well-placed to help solve, and we've been able to develop a system which shows that quantum computing could have valuable applications in gravitational wave astronomy.
"While we've concentrated on one type of search in this paper, it's possible that it could also be adapted for other processes which, like this one, don't require the database to be loaded into quantumFergus Hayes, a Ph.D. student in the School of Physics & Astronomy, is co-lead author of the paper.
