In large systems of interacting particles in quantum mechanics, an intriguing phenomenon often emerges: groups of particles begin to behave like single particles. Physicists refer to such groups of particles as quasiparticles.
A quantum gravity gradiometer has been demonstrated outside the lab for the first time, an advance that could reduce construction costs and delays.
The new gravity measurement device, known as a gravimeter, developed by the University of Birmingham, UK, use atoms to probe the gravitational field at two different points.
System codeveloped with RSK and Teledyne e2v based on telecoms lasers frequency-doubled to 780nm.
An object concealed below ground has been traced using quantum technology—a long-awaited breakthrough with deep implications for national security, industry, and human knowledge.
