Our main research interest is in the field of open nonequilibrium quantum systems, quantum transport, near-term and futuristic quantum technologies.

Disruptive quantum technologies are changing our life. Quantum entanglement, superpositions of macroscopic quantum states, measurement-induced state collapse, and wave-particle duality are no longer theoretical curiosities but working principles for emerging quantum high-tech, such as secure communication, sensing, and new types of computer hardware/software for exponentially fast computations and information processing.

The central focus of our research is the theory of quantum transport. The quantum transport  is the operating principle for atom-sized transistors, single-electron quantum "optics", new types of computer hardware with advanced and alternative informational processing, quantum computing architectures, and molecular scale sensors. We develop new conceptual theoretical methods for quantum transport and large-scale computer programs for simulation of atomic-sized nanoelectronic devices. All spectrums of advanced theoretical methods, ranging from quantum master equations and superoperators to Keldysh nonequilibrium Green's functions, have been actively used in our group research. 

Our research fits into a broader national ecosystem of groups working in quantum technology. What distinguishes us from other groups in Australia is our strong focus on educating a outstanding regional Australian talents by involving them in cutting edge quantum research - Quantum@North QLD: quantum-ready and quantum-literate North Queensland.

Today we focus on the following projects:

• Noise and fluctuations. Full counting statistics, waiting time distributions, first passage time in nonequilibrium open quantum systems
• Floquet quantum engineering: Nonequilibrium Green's functions methods for time-driven quantum systems
• Quantum mechatronics (classical degrees of freedom controlled by nonequilibrium quantum environment)
• Silicon-molecule-silicon quantum electronic circuits
• Spintronic devices
• Chiral induced spin selectivity in quantum transport
• Single-molecule piezoresistors and pressure sensors
