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…
Variational preparation of entangled states in a system of transmon qubits
Alexander Yeremeyev, Aleksei Tolstobrov, Gleb Fedorov +11
The conventional method for generating entangled states in qubit systems relies on applying precise two-qubit entangling gates alongside single-qubit rotations. However, achieving…
Highly stable aluminum air-bridges with stiffeners
Aleksey N. Bolgar, Daria A. Kalacheva, Viktor B. Lubsanov +4
Air-bridges play a critical role in the performance of microwave circuits integrated with superconducting quantum bits, and their mechanical stability is predominant for reliable o…
Direct experimental observation of sub-poissonian photon statistics by means of multi-photon scattering on a two-level system
A. Yu. Dmitriev, A. V. Vasenin, S. A. Gunin +4
A cascade of two-level superconducting artificial atoms -- a source and a probe -- strongly coupled to a semi-infinite waveguide is a promising tool for observing nontrivial phenom…
