Project objective

Atom interferometry provides extremely sensitive measurements of quantities such as rotations and accelerations. This project will theoretically investigate how quantum entanglement between atoms and photons can enhance the sensitivity of atom-interferometry. The aim of this project is to drastically enhance the sensitivity of atom interferometers, to deliver practical sensing devices of unprecedented sensitivity. This increased sensitivity may lead to new technologies, such as ultra-sensitive gravity gradiometers for the detection of mineral reserves, as well as important applications to fundamental physics, such as tests of fundamental theories beyond the standard model.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "QBAS" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an email (fabio@fabiodisconzi.com) and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
