Quantum Electromagnetics Division

Our mission is to provide the metrological foundation for strategic, emerging electronic, magnetic, and photonic technologies by developing high-precision measurement devices, systems, standards, and methodologies and disseminating them to address national needs.

We interact and collaborate with stakeholders in industry, academia, and other government agencies to ensure that we are responsive to their measurement needs in quantum electrical standards; advanced materials analysis using X-ray sensor arrays; superconducting electronics and nanomagnetics for high-speed, energy-efficient, future generation computing; and quantitative medical diagnostic imaging.

News and Updates

Uncrunching the Frequency Spectrum

The squeeze is here, and the crunch is coming. Soon. Explosive demand for high-speed wireless communication is placing growing pressure on the limited frequency

Projects and Programs

Amplifiers

Ongoing
To process quantum information it is important to have amplifiers with wide bandwidth, high dynamic range, and low noise.

Boulder Microfabrication Facility

Ongoing
Central to fulfilling many of the Division’s programmatic goals, and those of other divisions at NIST-Boulder, the Quantum Electromagnetics Division is

Cryogenics

Ongoing
Low temperatures suppress noise and make quantum phenomena accessible. As a result, cryogenics play a crucial role in precision measurements.

Optical Phantom for Producing a Time-Resolved Diffuse Reflectance Spectrum

NIST Inventors
Jeeseong C. Hwang
Patent Description Physikalisch-Technische Bundesanstalt (PTB) and NIST jointly developed a concept for a waveform synthesizer which can generate a controlled waveform with several picosecond (ps) time resolution. In a light-diffusing material, characteristics of the time-of-flight distribution (e.g

Patent Description Presently, there are no commercial tools for x-ray absorption and emission spectroscopy with picosecond time resolution. Additionally, there are no table-top tools for x-ray emission spectroscopy with picosecond time resolution. Previously, x-ray emission spectroscopy with this
Step-by-step process for making a self-aligned waveguide

Process for Making a Self-Aligned Waveguide

Patent Description This invention enables practitioners to achieve very narrow gaps, down to 0.1 µm, on long coplanar waveguides using optical lithography. This process is shown below. In step 1, a mask is defined on top of the metallic material to be used as the center trace of the coplanar
