Aleksey Ustinov is one of the most famous global experts on long Josephson transition lines and the physics of magnetic soliton waves — nonlinear waves in these structures. He devoted many years to the study of multilayer and discrete Josephson systems, his most cited works were published in these areas.
In 2000, Ustinov’s group discovered internal localized modes (discrete breathers) in arrays of Josephson contacts. In 2003, his group published in Nature a report about tunneling of Josephson vortex — the largest quantum object detected as of today.
In recent years, the major emphasis of his research has been on superconducting qubits. A remarkable achievement of Ustinov’s group was the demonstration in 2009 of extremely fast (the fastest reported to date) manipulation of superconducting qubit reaching 30 GHz frequency of coherent oscillations. Ustinov and his group investigated quantum-coherent dynamics of superconducting phase qubits, flux
qubits and transmons.
In 2011, the group led by Aleksey Ustinov for the first time demonstrates the frequency domain multiplexing readout of superconducting qubits (7 qubits were read out via a single measurement line) — a crucial step towards scalable quantum architecture, which is now followed by the leading global research groups.
His more recent works include, e.g., coherent manipulation of microscopic two-level defects in superconducting qubits, demonstration of a readout of qubit using a propagating fluxon, the first implementation of a quantum metamaterial using superconducting qubits.
The recent work includes qubit metamaterials consisting of both transmon and flux qubits, a circuit based on a fluxonium qubit with superinductance made of granular aluminum.
