Biography

Kavan studied Engineering Physics at Embry-Riddle Aeronautical University. He got his PhD from the University of Texas at Austin under the supervision of Professor George Sudarshan. He was a Research Fellow at the Centre for Quantum Technologies at the National University of Singapore, and then at Clarendon Labs at the University of Oxford. He was a Professor at Monash University and the Director of Centre for Quantum Technologies at Transport for New South Wales (aka Quantum for New South Wales).

Research interest

I am primarily interested in all facets of complex quantum dynamics and quantum stochastic processes. I have applied these ideas to characterise and control noise in quantum computers, to show that quantum chaos requires volumetric spatiotemporal entanglement, and existence of complex quantum processes that cannot be efficiently simulated by classical methods.

I have also worked in the field quantum information geometry, which includes quantum speed limits, stochastic thermodynamics, metrology and sensing, quantum energy kinematics, etc. He has also collaborated with experimental physicists, neuroscientists, computer scientist, and mathematicians.
