The Big Bell Test

IFN participates to the Big Bell test!

In a collaboration between Politecnico di Milano, University of Calgary, Kyoto University, IFN-CNR Milano and Trento, researchers demonstrated the fabrication of 3D optical circuits within the volume of diamond using focused ultrashort laser pulses.
The great interest in diamond is its rare defect called the nitrogen vacancy (NV) center, which can be exploited as a quantum bit, the building block for quantum information systems. The international team of collaborators demonstrated that the laser writing of optical waveguides in diamond did not deteriorate the remarkable properties of the NV centers, allowing photons to be efficiently carried between the defects, a crucial step in building a scalable quantum computing platform. The fabrication toolkit for diamond is similar to the one that has revolutionized silica planar lightwave circuits and could enable applications such as quantum information processing and efficient magnetometry using spin sensing, which would have a major impact on technology and society.

Nature Scientific Reports
Optical frequency comb sources provide thousands of precise and accurate optical lines in a single device enabling ultra-broad-band and high-speed detection spectroscopic measurements. Within a fruitful collaboration between Politecnico di Milano, University of Yale, and IFN-CNR Milano a novel spectroscopy technique based on the combination of a frequency comb source and a fibre spectrometer is developed able to resolve the single comb mode in 0.85 THz optical bandwidth. Being based on all-fibre technology, the system is inherently low-cost, lightweight and may lead to the development of a new class of broadband high-resolution spectrometers.
