Thomas Galley
Postdoctoral researcher at IQOQI Vienna
About me
I am a researcher in the foundations of quantum theory and quantum information theory. I obtained my PhD from University College London in 2018 studying modifications to the measurement postulates of quantum theory. Email address: (firstname) dot (lastname) at oeaw dot ac dot at
