Coherent Microoptics and Radiophotonics

Uniqueness

The laboratory is the leading one working with optical high-Q crystalline microresonators and microresonator based Kerr frequency combs. We can manufacture microresonators with any desired geometry using an industrial diamond turning.

The group was founded in March 2014. The main directions of research are associated with whispering gallery mode optical microresonators — tiny transparent disks or spheroids that can catch light (having a giant quality factor up to 1012). We are investigating different classical nonlinear and quantum effects in these resonators and are looking for practical applications. The most promising part of our work is associated with optical frequency combs which can be used in compact devices for high-precision spectroscopy, as ultrastable microwave sources, and to generate femtosecond optical pulses. Another interest of the group is microresonators composed of electrooptic materials for radiophotonic applications and cavity quantum electrodynamic experiments.

We are doing optical experiments with microresonator based optical frequency combs in visible and near infrared regions and are working on ultrasensitive microresonator based radiophotonic receivers

Quantum Polaritonics

June 2015 We co-author with the Vučković group in Stanford their observation of our predicted detuned photon blockade [Phys. Rev. Lett. 114:233601, 2015]

Exciton-polariton Rabi oscillations • Rabi and Josephson oscillations of polaritons; • Permanent Rabi oscillations; • Inverted pendulum regime of the polariton Rabi oscillator; • Quantum statistics of polariton condensates and Rabi oscillators.

Polaritonics deals with quasi-particles that bind light and matter into new eigenmodes combining antagonist properties such as high coherence inherited from light, and strong interactions from their matter counterpart. Polaritons appear ideal for quantum information processing, where both of these features are highly sought. Polariton physics gave a new and applied dimension to fundamental concepts such as BoseEinstein condensates or superfluids, also bringing them on-chip and up to room temperature. It develops quickly for classical optical devices, with polariton transistors already demonstrated, and the research into polariton simulators is very active, including from our group.

Founded in 2014, and since then the group collaborates with virtually all leading groups studying excitonpolaritons in Russia, EU, USA and Asia, and is highly solicited in international consortia dealing with the field of Polaritonics. The experimental component (since 2017) includes the fabrication and characterisation of novel nano-

Members

Modern quantum technologies are strongly oriented towards the construction of devices for quantum computation and the creation of new quantum materials in the nanoscale. Successful developments in these directions require new ideas with theoretical support. With this purpose, the Many-body Theory group was created at RQC in August 2013 (Georgy Shlyapnikov, Professor and group leader, and Alex Fedorov, student). In September 2013 Vladimir Yudson joined the group, and a few months later Oleg Lychkovskiy (now at Skoltech) completed the group. In the autumn of 2017 Vladimir Gritsev joined the group.

We work on discovering novel many-body topological quantum states and analyzing protected quantum information processing with these states, as well as finding novel quantum fluids and disordered systems with non-conventional transport properties

Research Topics • Topological quantum states and quantum information processing.

• Exotic quantum fluids and quantum transport.

• Non-conventional disordered quantum systems.

Highlight In summer of 2014 we invited Prof.

Boris Svistunov from the University of Massachusetts (one of the world leaders in Monte Carlo methods) to visit the RQC. He came having in his mind a rather negative opinion on the activities of RQC. However, after talking to theorists and visiting experimental labs, his opinion about the RQC became rather positive. This simply says that the RQC should be more active with inviting leading scientists.

The expertise that our group brings to the RQC lies in the area of ultrafast optical science. Central to our mission, as a group in a world leading center in quantum technologies, is to transform a tremendous and largely unreleased potential of ultrafast optics into powerful, yet compact tools — unique laser sources, fiber-optic neurointerfaces, novel fiber quantum sensors and sources of quantum states of light — which will push the frontiers of quantum technologies.

Quantum Simulators and Integrated Photonics The group was founded in 2013. The research directions are laser cooling and quantum simulations with thulium atoms; integrated solid state quantum circuits (including development of integrated detectors); integrated fiber systems of quantum logic with single atoms. The major field of our research is quantum simulation — the method of building a controllable quantum system to model a real hard to compute on a classical computer quantum system. Ultracold atomic ensemble localized in optical lattice is convenient platform for quantum simulations. A wide variety of simulation applications is promising: understanding of high-temperature superconductivity, the investigation of topological quantum matter; observation and control of quantum matter at the level of individual atoms; the exploration of fundamental phenomena in statistical physics. Thus, quantum simulation is a prospective approach to investigation of complex quantum systems.

Precision Quantum Measurements

Uniqueness The group has world’s leading position in studies of laser cooled Thulium atoms: for the first time we demonstrated laser cooling and trapping, laser excitation of the clock transition, determined the magic wavelengths. We develop ultrastable lasers with unprecedented phase stability and cover most challenging demands of optical clocks community in Russia.

May 2014 Signing agreement between RQC and P.N. Lebedev Institute for establishing of joint labs

Optical clocks • Optical lattice clock using magnetic dipole transition in Tm atoms; • Al+ optical ion clock; • Optical frequency links for time and frequency transfer; • Compact Yb+ ion clock for satellite applications.

Ultrastable lasers • ULE-stabilized lasers with sub-Hz spectral linewidth; • Cryogenic silicon cavities for laser stabilization; • Crystalline high-reflective mirrors for low thermal noise cavities.

The field of Precision Quantum Measurements deals with quantum sensors and optical clocks for variety of fundamental and applied research. Laser cooling and quantum manipulations with atoms and ions have variety of implementations in time and frequency metrology, global navigation systems, inertial navigation, gravimetry and quantum simulations. It opens new opportunities for sensitive tests of fundamental theories — search for variation of fundamental constants, tests of the Standard model, Lorents invariance, CPT theorem — and determination of fundamental constants.

Quantum manipulations with single ions in linear ion traps is one of the proved highways to high fidelity quantum computations.

Ions and atoms in quantum regime • Linear ion traps for elementary quantum gates; • Interactions of ultracold neutral atoms.

Besides fundamental studies, we develop frequency stabilized lasers with unprecedented frequency stability which are highly demanded for various precision measurements. In 2017 our group started development of transportable Yb+ ion clock which in short future should be implemented for space missions.

Superconducting quantum circuits have made truly amazing progress in the past decade. The coherence times of superconducting qubits increased by nearly six orders of magnitude during the past 15 years — from few nanoseconds to milliseconds. Our research on superconducting quantum circuits aims at scalable architecture of quantum processors, quantum simulators, and quantum metamaterials.

Master students: Vasilisa Usova Daria Kalacheva Technical staff: Sergei Egorov Nikolay Stepakov

Due to massive parallelism built into quantum hardware, quantum information processing would allow unprecedented computing power and could make feasible the modelling of complex systems and phenomena. Small scale special purpose quantum simulators would allow for modelling specific complex systems, for example, to design new materials and simulate the electronic structure of various chemical compounds. Our research interests within superconducting quantum circuits span from new readout techniques and qubit designs to quantum metamaterials and quantum simulation.

Research Topics

Quantum Optics In order to make quantum optics suitable for technological applications, we require a powerful quantum engineering toolbox that would allow us to synthesize, manipulate and characterize complex quantum states of the electromagnetic field. The past fifteen years brought us a long way forward towards this end, and there is even more work that remains to be done.

Our continuous-variable quantum optics lab is unique in Russia.

• Developing methods of quantumenhanced sensing and metrology that are tolerant to optical losses.

• Converting quantum information between discrete- and continuousvariable encodings.

High school outreach In addition to research, we set up classes on quantum mechanics for talented students of Moscow high schools. These weekly two-hour classes employed a tutorial system in which each student did the reading and solved homework problems at home, and then discussed them with the tutor in class. The program included the notions of Hilbert space, quantum states, operators, axioms of quantum physics, measurements, the Schrodinger equation, quantum paradoxes, nonlocality, Bell inequalities, quantum cryptography, teleportation, and computing. Ten our students graduated in 2013.
