However, qubits based on electron spins in semiconductor quantum dots have proven challenging to couple to microwave photons. In this theoretical work we show that a sizable coupling for a single electron spin is possible via spin-charge hybridization using a magnetic field gradient in a silicon double quantum dot. Based on parameters already shown in recent experiments, we predict optimal working points to achieve a coherent spin-photon coupling, an essential ingredient for the generation of long-range entanglement. Furthermore, we employ input-output theory to identify observable signatures of spin-photon coupling in the cavity output field, which may provide guidance to the experimental search for strong coupling in such spin-photon systems and opens the way to cavity-based readout of the spin qubit.</dcterms:abstract> <dcterms:title>Input-output theory for spin-photon coupling in Si double quantum dots</dcterms:title> <dc:contributor>Mi, Xiao</dc:contributor> <bibo:uri rdf:resource=""/> <dspace:isPartOfCollection rdf:resource=""/> <dc:creator>Petta, Jason R.</dc:creator> <dc:language>eng</dc:language> <dc:creator>Taylor, Jacob M.</dc:creator> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:creator>Burkard, Guido</dc:creator> <dc:contributor>Benito, Monica</dc:contributor> <dc:contributor>Taylor, Jacob M.</dc:contributor> </rdf:Description> </rdf:RDF>
