Laboratory of the Physics of Quantum Information Technology

This laboratory develops quantum devices for information processing, as well as the methods that enable their operation. The main lines of work pursued now are quantum sensor design, quantum protocol development and implementation, fundamental quantum thermodynamics research, and quantum amplifiers.

Quantum metrology

The laboratory develops algorithms and applies them in experiments with qubits realized as transmons in the qubit and qutrit modes. Experiments involving flux qubits are also projected. The team’s further plans include metrological experiments on qudit chips within the framework of linear optics. The development and design of optical random number generators will also be pursued.

Quantum thermodynamics

The lab implements the quantum protocols it creates on the IBM openly accessible five-qubit computer. Among such protocols is the time reversal algorithm. Other quantum thermodynamics studies focus on the H-theorem and quantum Maxwell’s demon implementation. While there is little doubt that this research has fundamental significance, with time, it may acquire a practical dimension as well.

Quantum amplifiers

Pushing quantum sensor sensitivity to the physically possible limit will require amplifiers with the ultimate quantum efficiency. The laboratory cooperates with researchers from Aalto University in Finland in developing and testing such amplifiers. Sample devices are expected to be manufactured at MIPT.

Quantum algorithms and hardware

The laboratory is engaged in developing computational algorithms for chips comprising multiple qubits, as well as experimentally implementing such chips using artificial atoms of various kinds. The long-term agenda also provides for the development of quantum computing hardware components based on superconductors whose transition temperature exceeds that of aluminum.

Plans for 2019

The team intends to leverage the lab’s own resources to expand its metrology research in the framework of linear optics. Research involving superconducting qubit (transmon) fabrication and measurements will be carried out at Aalto University, Finland, with some work done at MIPT. Quantum sensors of the electromagnetic field based on two qubits will be developed and manufactured.
