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…
The microwave phase locking in Bloch transistor
Ilya Antonov, Rais Shaikhaidarov, Kyung Ho Kim +5
Recent experimental demonstration of the quantum coherent phase slip and current quantization in the superconductors, the fundamental phenomena dual to the coherent Cooper pair tun…
Aharonov-Casher Effect and the Coherent Flux Tunneling in the Hybrid Charge Quantum Interference Device
J. W. Dunstan, R. Shaikhaidarov, K. H. Kim +6
By exploiting the Aharonov-Casher effect we demonstrate a suppression of magnetic flux tunneling in a Hybrid Charge Quantum Interference Device. The main part of this device is two…
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…
Quantized current steps due to the synchronization of microwaves with Bloch oscillations in small Josephson junctions
Rais S. Shaikhaidarov, Kyung Ho Kim, Jacob Dunstan +4
Synchronization of Bloch oscillations in small Josephson junctions (JJs) under microwave radiation, which leads to current quantization, has been proposed as an effect that is dual…
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…
