Dr Lund is a theoretical quantum physicist at The University of Queensland. He received his PhD at The University of Queensland where he developed a new encoding for optical quantum information based on Schrodinger cat states. In 2009 he was awarded a post-doctoral fellowship at Griffith University where he worked in the group of Professor Wiseman on quantum measurement theory. In 2011 he joined the CQC2T node at UQ in the group of Professor Timothy Ralph and worked on quantum computational speed-ups in optical systems.

A key result from Dr Lund’s research is from the computational hardness of quantum optical sampling from Gaussian states of light. This result, now commonly known as “Scattershot Sampling”, allowed for a quantum optical sampling problem, that is computationally hard for classical computers, to be generated from so called “Gaussian” states of light that are simpler to generate experimentally. He has also made important contributions to the theory of quantum uncertainty relationships by showing how they can be constructed through weak quantum measurements. Dr Lund is the co-inventor, with Professor Ralph, of the quantum non-deterministic noiseless linear amplification protocol which has led to advances in quantum key distribution and quantum repeater technologies.
