- Abstract: This Thesis delves into the development and implementation of quantum
algorithms using the digital-analog quantum computing (DAQC) paradigm. It
provides a comparative analysis of the performance of DAQC versus traditional
digital approaches, particularly in the presence of noise sources from current
noisy intermediate-scale quantum (NISQ) devices. The DAQC paradigm combines the
strengths of digital and analog quantum computing, offering greater efficiency
and precision for implementing quantum algorithms on real hardware. The Thesis
focuses on the comparison of four relevant quantum algorithms using digital and
digital-analog approaches, and the results show significant advantages in favor
of the latter. Furthermore, the Thesis investigates the cross-resonance effect
to achieve efficient and high-precision Hamiltonian simulations. The findings
indicate that the digital-analog paradigm is promising for practical quantum
computing applications. Its ability to deliver greater efficiency and accuracy
in implementing quantum algorithms on real hardware is a significant advantage
over traditional digital approaches.
