- Abstract: The ability to detect single photons has become increasingly essential due to
the rise of photon-based quantum computing. In this theoretical work, we
propose a system consisting of a quantum dot (QD) side-coupled to a
superconducting nanowire. The coupling opens a gap in both the QD mode and the
Majorana zero mode (MZM) at the nanowire edge, enabling photon absorption in
the system. We show that the absorbed photoelectron decays via rapid
(sub-nanosecond to nanosecond) nonradiative heat transfer to the nanowire
phonon modes rather than by spontaneous emission. Furthermore, we calculate the
temperature increase and associated resistance increase induced by the
absorption of a photon for a given appropriate set of material and
environmental parameters, yielding a temperature increase in the millikelvin
range and a resistance increase in the kiloohm range, vastly exceeding the
photon-absorption-induced temperature and resistance increases for competing
2D-3D hybrid systems by 5 and 9 orders of magnitude, respectively. Lastly, we
determine the detector efficiency and discuss the system density required for
deterministic photon number measurement, demonstrating that a photon absorption
probability of over 99.9 percent can be achieved for an integrated system
consisting of an array of nanowire-QD complexes on-chip inside a cavity. Our
results thus provide a basis for a deterministic microwave photon number
detector with an unprecedented photon-number-detection resolution.
