The University of Auckland, NIST, UMD, and UC Santa Barbara demonstrated a chip-scale octave-spanning microcomb that enables stable, low-noise optical frequency metrology on a scalable photonic chip. This breakthrough supports deployable optical atomic clocks, GPS-denied quantum navigation, and precision quantum sensing with applications in defense and quantum photonics commercialization.
This Wire brief sits within Fusion42's coverage of Quantum Computing.
◆ ◆ The Wire takeaway
Your quantum sensing or navigation device can now become far more compact and deployable thanks to photonic chips that deliver stable, broad-spectrum optical frequency combs. This opens direct access to satellite-independent timekeeping and precision measurements without bulky equipment.
