Roberto Campos and Gabriel Escrig, UCMadrid: Applying Quantum Computing to Gravitational Wave Parameter Estimation

Abstract: Since the first detection of gravitational waves (GWs) generated by a pair of black holes in 2015, the field has rapidly advanced. Yet current analysis techniques are bottlenecked by high computational demands. Our exploration demonstrates that quantum computing offers a promising alternative to tackle these challenges. In this talk, we will introduce a quantum algorithm (named qBIRD) for gravitational wave parameter estimation, the estimation of source properties. We will also introduce the Quantum Metropolis Solver (QMS), a quantum software tool based on the Metropolis-Hastings algorithm and quantum walks, and an important part of the qBIRD algorithm. Testing on observed GW data from detectors like LIGO reveals a polynomial advantage from QMS. We will showcase the applications of qBIRD on estimating black hole properties such as masses and distance.
