Phase statistics of a single qubit emission as a direct probe of its coherence
A. Sultanov, E. Mutsenik, L. Kaczmarek +4
The emission of photon from an individual atom encodes the phase of its initialized quantum state. Using single-shot heterodyne detection, we measure the phase distribution of the…

Measuring coherent dynamics of a superconducting qubit in an open waveguide
Aidar Sultanov, Evgeniya Mutsenik, Matthias Schmelz +5
We measured the relaxation and decoherence rates of a superconducting transmon qubit in a resonator-free setting. In our experiments, the qubit is coupled to an open coplanar waveg…

Basic cell for a quantum microwave router
Evgeniya Mutsenik, Aidar Sultanov, Leonie Kaczmarek +4
We report the first experimental realization of a scalable basic cell for quantum routing, enabling coherent control and exchange of microwave photons between two spatially separat…
