Tommaso Demarie

Post Doc Research Fellow


Pillar / Cluster: Engineering Product Development

SUTD Advisor

Joseph Fitzsimons


Tommaso is a theoretical physicist with interests in quantum information and computation theory. He holds a BSc and a MSc from the Universita’ degli studi di Torino, Italy, and a PhD from Macquarie University, Australia. His doctoral research focused on the interplay between the geometry of quantum states and their physical properties, with a particular focus on the topological description of a continuous-variable analog of the surface code. Tommaso joined Prof. Fitzsimons’ group in mid 2014 and his recent research interests include quantum cryptography, entanglement theory and topological quantum computation.
