Photonic Thermometry

Ongoing
Why do we need reliable temperature metrology? Temperature, the second most measured physical property after time and frequency, is indispensable to innumerable industries, military services, medicine, climate, and weather forecasts – precise, accurate, and rapid temperature metrology enables much

Power Conditioning Systems for Renewables, Storage, and Microgrids

Ongoing
Objective: To establish standards and measurement methods, and test for smart grid and microgrid Power Conditioning Systems needed to transition from today’s low penetration of nondispatchable intermittent renewable energy sources to flexible grid operations that can actively adjust to varying grid

Precision Electro-Mechanical Experiments (PREME)

Ongoing
NIST-4 Kibble Balance Previously called ‘the Electronic Kilogram’ Project, a major component of PREME is the realization of SI unit of mass, the kilogram, using the NIST-4 Kibble balance, the fourth generation of Kibble balances at NIST. This is accomplished through a high-accuracy comparison of

Precision metrology with integrated photonics

Ongoing
This project develops integrated photonics– devices based on waveguides that are fabricated in a nanoscale device layer on a silicon wafer –for the purposes of exploring nonlinear science, enabling new applications with scalable integrated photonics light sources, and enhancing classical and quantum

Prototyping Platforms for Emerging Technologies

Ongoing
Emerging technologies aim to overcome traditional memory limitations with higher density, lower power consumption, faster read/write speeds, better endurance, and lower cost [2]. Many new candidate memory elements are analog or stochastic, requiring new testing infrastructure, and the context of

Proximity Detection for Electronic Contact Tracing

Completed
We are developing performance metrics for not just ranging, but also for detecting close contacts, which in the context of COVID-19 is the situation where two people are less than six feet apart with no obstacles between them. Obviously, the duration of a close contact is important, as it affects

Ongoing
The BCQT serves as a resource to academic and industry quantum research groups for measurement of superconducting microwave resonators in a well-characterized cryogenic environment using traceable, open-source methods developed in broad consultation with companies, universities, and NIST. This

Quantum Conductance

Ongoing
The quantum Hall effect (QHE), and devices that exhibit it, will continue to serve as the foundation of the ohm while also expanding its territory into other SI derived units. The world adopted the quantum SI in 2019, and it remains essential that the global metrology community pushes forth and

Quantum Radiometry

Ongoing
For quantum applications, it is important to generate quantum states of light and detect them with extremely high efficiency. This project explores the metrology challenges associated with precision measurement of single photon sources and detectors. The classical photonic radiometry techniques used

Quantum Voltage Project

Ongoing
Researchers in the Quantum Voltage Project develop and disseminate highly accurate instruments that exploit the quantum mechanical properties of superconductive devices known as Josephson junctions (JJs), as well as measurement techniques and best-practices for using these instruments. When a JJ is

Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing
Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose

Strain Measurement for Semiconductor Devices

Ongoing
Mechanical strain is hugely important to semiconductor devices and packages while also being difficult to measure accurately. Strain is engineered into CMOS channels to improve carrier mobility for higher performance at lower power but is also intrinsically present from manufacturing processes where

Strain Measurement for Semiconductor Devices and Packages

Ongoing
Strain is a critical parameter that influences both electrical and mechanical failures of devices, however, measuring strain in complex 3D geometries and vanishingly small feature sizes remains a challenge for manufacturers. Data provided by strain measurements can be used to validate computational

Temporal Computing

Ongoing
In standard integrated circuits, information that is coded as ones and zeros is implemented by voltages on wires being high or low. The circuits consume energy during transitions between these voltages. Binary numbers have a voltage per bit so there are a lot of transitions each time a number
