Valerio Scarani's research group

We are a research group in theoretical quantum information, based in the Centre for Quantum Technologies (CQT), National University of Singapore (NUS). We are part of the vibrant quantum ecosystem in Singapore QuantumSG.

Research topics at a glance

Our research topics span from foundations to the description of real devices. In the past years, we have worked on Quantum Key Distribution, Bell Nonlocality and device-independent certification (check out the book), and the description of optical experiments, with a recent excursion into quantum thermodynamics.

The current outlook revolves around quantum devices and complex systems, with topics like:

  • Theory of hybrid quantum systems
  • Complexity and nonlocality of many-body states
  • Pushing the Heisenberg cut towards larger systems
