Query: Coherent long-distance spin-qubit-transmon coupling   Spin qubits and superconducting qubits are among the promising candidates for
a solid state quantum computer. For the implementation of a hybrid architecture
which can profit from the advantages of either world, a coherent long-distance
link is necessary that integrates and couples both qubit types on the same
chip. We realize such a link with a frequency-tunable high impedance SQUID
array resonator. The spin qubit is a resonant exchange qubit hosted in a GaAs
triple quantum dot. It can be operated at zero magnetic field, allowing it to
coexist with superconducting qubits on the same chip. We find a working point
for the spin qubit, where the ratio between its coupling strength and
decoherence rate is optimized. We observe coherent interaction between the
resonant exchange qubit and a transmon qubit in both resonant and dispersive
regimes, where the interaction is mediated either by real or virtual resonator
photons.
