A fundamental goal of strong interaction physics is to describe and interpret scattering experiments from first principles quantum chromodynamics (QCD) and to understand the internal structure of nuclei. However, the complexity of QCD, particularly in its non-perturbative regime, presents major challenges. Classical computing techniques, while driving substantial progress, have inherent...
By leveraging many years of development by the materials science, quantum computing, astronomy, and AMO communities, we have entered an era where practical precision experiments are possible (and already taking data) in subatomic physics with superconducting sensors. These devices are characterized by their exceptionally high energy resolution and low thresholds for the detection of various...
We present an efficient quantum circuit for block encoding a pairing Hamiltonian often studied in nuclear physics. Our block encoding scheme does not require mapping the creation and annihilation operators to the Pauli operators and representing the Hamiltonian as a linear combination of unitaries. Instead, we show how to encode the Hamiltonian directly using controlled swap operations. We...
