  Digital-Analog Quantum Computation (DAQC) has recently been proposed as an
alternative to the standard paradigm of digital quantum computation. DAQC
creates entanglement through a continuous or analog evolution of the whole
device, rather than by applying two-qubit gates. This manuscript describes an
in-depth analysis of DAQC by extending its implementation to arbitrary
connectivities and by performing the first systematic study of its scaling
properties. We specify the analysis for three examples of quantum algorithms,
showing that except for a few specific cases, DAQC is in fact disadvantageous
with respect to the digital case.
