A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies ...

For experiments that require ultra-precise measurements and control over atoms -- think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates -- lasers are the technology of ...

Laser frequency combs are light sources that produce evenly spaced, sharp lines across the spectrum, resembling the teeth of a comb. They serve as precise rulers for measuring time and frequency, and ...

A precision voltage reference is useful in the lab for checking your multimeters. This post describes the construction of a poor man’s precision voltage reference. It is great for checking any ...

Forbes contributors publish independent expert analyses and insights. Dave Altavilla is a Tech Analyst covering chips, compute and AI. As mobile devices continue to take on more complex tasks—from ...

Impressively, the unit registered the lowest frequency loss of any chip to date. Specifically, the engineers noted that the new chip was 15x more stable and 100x more efficient in terms of microwave ...

In my previous design idea, a design for a simple GPS disciplined oscillator (GPSDO) 10 MHz reference was presented. A note at the end of that article describes the realization that a frequency ...

New silicon nitride microresonator cuts timing jitter in soliton microcombs, boosting precision for lidar, quantum metrology, and ultrafast communications. (Nanowerk News) Laser frequency combs are ...
