My project aims to develop quantum computing algorithms to perform calculations associated with many-body nuclear systems. As the number of particles in a many-body nuclear system increases, the size of the associated Hamiltonian increases exponentially. This creates a problem for classical computers where large problems become essentially unsolvable. Quantum computing can address this issue due to the exponential nature of quantum bits, where additional qubits increase the size of the Hilbert space exponentially. Current quantum computers have large amounts of noise and are prone to large error rates, limiting the types of algorithms that can be performed on quantum hardware. Hybrid algorithms provide some form of solution, where small quantum circuits with low circuit depth are able to be run with sufficiently low error rates to produce meaningful results in tandem with a classical computer. These hybrid algorithms allow for some calculations to be performed on many-body nuclear systems, including ground-state energy and nuclear excited state spectra calculations.
