Kinemon: inductively shunted transmon artificial atom
Daria Kalacheva, Gleb Fedorov, Julia Zotova +4
We experimentally investigate inductively shunted transmon-type artificial atoms as an alternative to address the challenges of low anharmonicity and the need for strong charge dis…
Hybrid quantum learning with data re-uploading on a small-scale superconducting quantum simulator
Aleksei Tolstobrov, Gleb Fedorov, Shtefan Sanduleanu +11
Supervised quantum learning is an emergent multidisciplinary domain bridging between variational quantum algorithms and classical machine learning. Here, we study experimentally a…
The quantum and classical field scattered on a single two-level system
Sergei Gunin, Andrei Vasenin, Aleksei Dmitriev +3
In many problems, the scattering amplitudes of weak coherent pulse are almost equivalent to the ones of single propagating photon. We thoroughly compare the scattering of: (i) shor…
Overcoming photon blockade in circuit QED single-atom maser with engineered metastability and strong coupling
A. A. Sokolova, D. A. Kalacheva, G. P. Fedorov +1
Reaching high cavity population with a coherent pump in the strong-coupling regime of a single-atom laser is impossible due to the photon blockade effect. In this work, we experime…
Photon transport in a Bose-Hubbard chain of superconducting artificial atoms
G. P. Fedorov, S. V. Remizov, D. S. Shapiro +8
We demonstrate non-equilibrium steady-state photon transport through a chain of five coupled artificial atoms simulating the driven-dissipative Bose-Hubbard model. Using transmissi…
Single-atom maser with engineered circuit for population inversion
A. A. Sokolova, G. P. Fedorov, E. V. Il'ichev +1
We present a blueprint for a maser with a single three-level transmon superconducting artificial atom. The system can be pumped coherently via a two-photon process, and to achieve…
Light-dressing of a diatomic superconducting artificial molecule
G. P. Fedorov, V. B. Yursa, A. E. Efimov +8
In this work, we irradiate a superconducting artificial molecule composed of two coupled tunable transmons with microwave light while monitoring its state via joint dispersive read…
Automated analysis of single-tone spectroscopic data for cQED systems
G. P. Fedorov, A. V. Ustinov
Physical systems for quantum computation require calibration of the control parameters based on their physical characteristics by performing a chain of experiments that gather most…
