Jan Hall of NIST and JILA shared the 2005 Nobel Prize in Physics for pioneering work in laser precision, specifically the development of optical frequency combs. While this article does not discuss a specific quantum computing standard, the technology serves as a foundational measurement tool. The National Institute of Standards and Technology (NIST) and the joint JILA research institution were the primary organizations behind this achievement, which established a new method for measuring light frequencies with extreme accuracy.
The key technical achievement involves a laser that produces a series of short, equally spaced light pulses, creating a frequency “comb” that acts like a ruler for measuring other lasers. This method allows for frequency measurements accurate to one part in a quadrillion, improving master clocks and global positioning systems with significant potential impact on quantum technologies. This research spans a 40-year period, culminating in the 2005 award, and continues to support NIST’s mission in precision metrology and the training of new physicists.
