The gateway to the quantum internet.
QphoX logo
Our quantum transducer is based on coupling microwave and optical photons through a mechanical intermediary resonator. This process is based on the piezo-electric and optomechanical effects and is fully coherent and works bi-directionally.

By converting quantum information between the microwave domain and optical telecom frequencies, our transducers allow for low-loss and high-fidelity transmission of quantum states.

Low thermal conductivity optical fibers carry the quantum states in and out of the cryostat, where they can be measured or routed through an optical network.

Research Scientist (Delft University of Technology, 2020 – 2021)
Master's Degree Applied Physics (Delft University of Technology, 2018 – 2020)
CTO at EC3 Technologies, Leo Technologies, Veloce (2013 – 2018)
Bachelors Degree Chemical Engineering (Vanderbilt University, 2006 – 2010)

I've spent many years designing and leading teams of engineers in RF and optoelectronics hardware design and embedded firmware development for medical instrumentation, sensors, and wireless transceivers. More recently, my work has focused on quantum information processing – in particular, superconducting quantum circuits and interfacing with optomechanical devices for quantum transduction.

Professor of Quantum Physics (Delft University of Technology, 2014 –)
Postdoc (California Institute of Technology, 2011 – 2014)
PhD in Physics (University of Vienna, 2006 – 2011)

During my scientific career I've been seeking to probe the very foundations of quantum physics and push the boundaries of our understanding of physics in general. My group's research is centered around quantum optomechanics and quantum optics experiments using photonic and phononic crystal devices, how this can lead to tests of quantum effects in macroscopic systems and novel quantum technologies.
