Physicists have developed a highly precise and ultra-sensitive atomic clock based on ytterbium, which ...
For the first time, an international team of physicists has successfully harnessed a rare orbital transition in atoms of ...
Claire Cramer, the executive director of quantum science at the University of California, Berkeley, who was in attendance, expressed optimism about the potential of solid-state nuclear clocks: “This ...
The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the ...
A photon emitted from a star a billion light-years away arrives at a telescope having experienced no time whatsoever. Not ...
A string of experiments using thorium-229 nuclei has brought the long-theorized nuclear clock closer to reality, producing frequency measurements stable enough to challenge the atomic clocks that ...
Researchers have shown that a single photon carrying quantum information can travel down kilometers of noisy real-world fiber ...
Chip-scale laser controls trapped ions for quantum clocks and qubits, enabling portable, scalable systems with high fidelity for sensing, computing, and space use.
We never measure time directly; instead, we use clocks to measure moments in time, meaning “time” is just a measurement of ...
A spacecraft traveling at 99 percent the speed of light toward Alpha Centauri would cross 4.3 light-years in what feels like months to its crew, while decades tick by on Earth. That asymmetry is not ...
Physicists report creating a time crystal with unprecedented detail, showing stable oscillations without energy loss. The ...
