This abstract introduces a novel geophysical quantum-annealing application utilizing the Quadratic Unconstrained Binary Optimization (QUBO) algorithm. The algorithm addresses the sparse spike deconvolution (SSD) as a QUBO problem to derive reflectivity from seismic CDP stacks. Initially, we provide a theoretical description of the QUBO algorithm. Subsequently, we present the formulation and mapping of SSD to the QUBO framework. We then apply this approach to a real-world problem, demonstrating various parameters and their impact on the output reflectivity.
