A linear path to efficient quantum technologies

Researchers at the University of Stuttgart have demonstrated that a key ingredient for many quantum computation and communication schemes can be performed with an efficiency that exceeds the commonly assumed upper theoretical ...

A simpler way to connect quantum computers

Researchers have a new way to connect quantum devices over long distances, a necessary step toward allowing the technology to play a role in future communications systems.

Do measurements produce the reality they show us?

Whenever the precision of a measurement approaches the uncertainty limit defined by quantum mechanics, the outcomes of the measurement depend on the dynamics of the interactions with the meter used to determine a physical ...

NASA's space-based quantum science lab keeps getting better

On Tuesday, Aug. 1, a major hardware update for NASA's Cold Atom Lab lifted off aboard a Northrop Grumman Cygnus resupply spacecraft on its way to the International Space Station. About the size of a small refrigerator, the ...

Sensing and controlling microscopic spin density in materials

Electronic devices typically use the charge of electrons, but spin—their other degree of freedom—is starting to be exploited. Spin defects make crystalline materials highly useful for quantum-based devices such as ultrasensitive ...
