abstract = {Quantum Hall edge states have some characteristic features
that can prove useful to measure and control solid state
qubits. For example, their high voltage to current ratio and
their dissipationless nature can be exploited to manufacture
low-loss microwave transmission lines and resonators with a
characteristic impedance of the order of the quantum of
resistance h/e2∼25kΩ. The high value of the impedance
guarantees that the voltage per photon is high, and for this
reason, high-impedance resonators can be exploited to obtain
larger values of coupling to systems with a small charge
dipole, e.g., spin qubits. In this paper, we provide a
microscopic analysis of the physics of quantum Hall effect
devices capacitively coupled to external electrodes. The
electrical current in these devices is carried by edge
magnetoplasmonic excitations and by using a semiclassical
model, valid for a wide range of quantum Hall materials, we
discuss the spatial profile of the electromagnetic field in
a variety of situations of interest. Also, we perform a
numerical analysis to estimate the lifetime of these
excitations and, from the numerics, we extrapolate a simple
fitting formula which quantifies the Q factor in quantum
Hall resonators. We then explore the possibility of reaching
the strong photon-qubit coupling regime, where the strength
of the interaction is higher than the losses in the system.
We compute the Coulomb coupling strength between the edge
magnetoplasmons and singlet-triplet qubits, and we obtain
values of the coupling parameter in the order of 100 MHz;
comparing these values to the estimated attenuation in the
resonator, we find that for realistic qubit designs the
coupling can indeed be strong.},
