About the Group
The RQC and MISIS are two labs in Russia which initiated experiments with superconducting qubits. In 2013, we performed first measurement of a qubit in Russia, and in 2015, jointly with MIPT, we fabricated our own qubits
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 architectures of quantum processors, construction of quantum simulators, and studies of quantum metamaterials.
Due to massive parallelism built into the quantum hardware, quantum information processing would allow unprecedented computing power and could make feasible the modeling of extremely complex systems and physical phenomena. Small scale special purpose quantum simulators would allow for modeling specific complex systems, for example, to design new materials and to 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 simulators.
In 2016, the RQC and MISIS labs joined efforts with collaborators at MIPT, NSTU, and ISSP to form a Russian Superconducting Qubit Consortium. The Consortium became the base for the Russian Superconducting Quantum Processor Project funded by the Russian Foundation for Advanced Research and targeted towards demonstration of multi-qubit circuits and simple quantum algorithms by the end of 2019.
