A clock accurate to within a tenth of a second over 14 billion years – the age of the universe – is the goal of research being reported this week by scientists from three different institutions.
Using optically dense, ultra-cold clouds of rubidium atoms, researchers have made advances in three key elements needed for quantum information systems â€“ including a technique for converting photons carrying quantum data to wavelengths that can be transmitted long distances on optical fiber telecom networks.
Physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms.
