Invited Speaker / Conférencier(ère) invité(e)

The Leggett–Garg inequality (LGI) was originally proposed as a way to test “macrorealism”: the classical intuition that a system always possesses definite properties, whether or not we look. In this talk, I will describe how a trilogy of experiments on LGI takes us from precision tests of quantum reality to a practical route for certifying randomness, culminating in our QRange quantum random...

The vision of a global quantum internet is at once ambitious and enthralling, but building metropolitan quantum key distribution (QKD) networks faces real world challenges, including atmospheric turbulence, channel loss, and the need for synchronization between users.
The application of metropolitan-scale quantum key distribution (QKD) networks is a critical step toward global quantum-secure...

The implementation of metropolitan-scale Memory-Assisted Measurement-Device-Independent Quantum Key Distribution (MA-MDI-QKD) stands as a crucial milestone on the pathway to global quantum secure communication. In this presentation, I will present a simplistic and intuitive stochastic model to predict key distribution rates in a MA-MDI-QKD scheme that addresses the real world parameters...
