“Mosaic” addresses this challenge, aiming at demonstrating multimode entangled quantum states with Josephson meta-materials.
Quantum states of light consisting of many entangled modes (multimode entangled states) provide a powerful quantum resource and have been recently proposed as a platform for universal quantum computing.
The aim of this project is to generate broadband multimode entangled states for the first time in the microwave regime.
Superconducting quantum circuits, specifically, Josephson meta-materials, are used to generate and control quantum correlations between different frequency modes in microwave photons.
The experimental proof that Josephson-metamaterial can be successfully used as sources of itinerant quantum states of microwave radiation represents a decisive step forward for the exploration of novel microwave photonics experiments for quantum technology applications.
The second key achievement is the first demonstration of two-mode squeezing generation in a travelling wave parametric amplifier. The novel Reversed Kerr TWPA, developed in the first part of the project, has been successfully used as a source of multimode entanglement. This experimental result is the main milestone of the whole project.
Such a key achievement opens an interesting avenue to the use of TWPA devices as a playground for microwave photonics experiments.
