Experimental quantum hamiltonian learning using a silicon photonic chip and a nitrogen-vacancy electron spin in diamond

2017

Summary form only given. The efficient characterization and validation of the underlying model of a quantum physical system is a central challenge in the development of quantum devices and for our understanding of foundational quantum …

A trusted-node-free eight-user metropolitan quantum communication network

2020 · Conference on Lasers and Electro-Optics

Complex quantum networks are vital for quantum technologies. Entanglement based networks are the most versatile in terms of supported applications (including beyond just quantum communication). Here we present an 8 user city wide entanglement network.

Field trial of a dynamically switched quantum network supporting co-existence of entanglement, prepare-and-measure QKD and classical channels

2023 · IET conference proceedings.

We present an 8-user quantum network supporting entanglement distribution, prepare-andmeasure quantum key distribution, Tbps level classical communication, their co-existence and switching capability in a metro network with over 50 km of field-deployed fibre.
