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…
Resistive method for measuring the disintegration speed of Prince Rupert's drops
Daria Gusenkova, Mark Bochkov, Evgenii Glushkov +2
We have successfully applied the resistance grid technique to measure the disintegration speed in special type of glass objects, widely known as Prince Rupert's drops. We use a dig…
