Single Artificial Atom SASER
Shtefan V. Sanduleanu, Peter Yu. Shlykov, Alexei N. Bolgar +7
Lasing - an effect of orthodox quantum mechanics - was discovered in 1955 and recognized by the Nobel Prize in 1964 due to its fundamentality. Nowadays, lasers and masers routinely…
Tunable compact on-chip superconducting switch
Julia Zotova, Alexander Semenov, Rui Wang +3
We develop a compact four-port superconducting switch with a tunable operating frequency in the range of 4.8 GHz -- 7.3 GHz. Isolation between channel exceeds 20~dB over a bandwidt…
Control and readout of a transmon using a compact superconducting resonator
Julia Zotova, Shtefan Sanduleanu, Gleb Fedorov +3
We demonstrate control and readout of a superconducting artificial atom based on a transmon qubit using a compact lumped-element resonator. The resonator consists of a parallel-pla…
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…
Compact superconducting microwave resonators based on Al-AlOx-Al capacitor
Julia Zotova, Rui Wang, Alexander Semenov +5
We address the scaling-up problem for superconducting quantum circuits by using lumped-element resonators based on an alternative fabrication method of aluminum -- aluminum oxide -…
Experimental demonstration of a two-dimensional phonon cavity in the quantum regime
A. N. Bolgar, J. I. Zotova, D. D. Kirichenko +4
The quantum regime in acoustic systems is a focus of recent fundamental research in the new field of Quantum Acoustodynamics (QAD). Systems based on surface acoustic waves having a…
