Qubit Gate And Producing A Generalized Controlled-Not Quantum Gate

NIST Inventors
Adam Kaufman and Alexey Gorshkov
Electric dipoles such as Rydberg atoms and polar molecules are among the most promising candidates for building a quantum computer. We propose a protocol that uses long-range dipole-dipole interactions in these systems to quickly implement a generalized controlled-not (CNOT) quantum gate, in which
Serial cytometry involves making repeated measurements of single objects as they pass through multiple interrogation regions in a microfluidic channel. Integrated optical waveguides deliver and collect light from objects. Matching and analysis of signals from individual cells, for example, enable uncertainty estimates on the biomarker content of each cell, which enables better comparison and classification of cells and mixture of cells.

Serial Cytometry

NIST Inventors
Gregory A Cooksey , Paul Patrone and Anthony J. Kearsley
NIST scientists have developed a microfluidic flow cytometer that is capable of robust and repeated measurements that provide first-of-their-kind uncertainty estimates, which support better comparability and classification of cytometry data. The device measures single objects in flow several times

Superconducting Vortex-Based Microwave Circulator

NIST Inventors
Jacob Taylor
This invention consists of a design model of a microwave circulator reliant on the motion of a single persistent-current vortex in a small superconducting circuit of Josephson junctions to induce nonreciprocal behavior. The model indicates the capability of enabling a small-scale, moderate-bandwidth

System And Method For Data Analysis In Quantitative PCR Measurements

NIST Inventors
Anthony J. Kearsley , Paul Patrone , Erica Romsos and Peter M. Vallone
In quantitative polymerase chain-reaction (qPCR) measurements, accurately subtracting background signals, quantifying the amount of DNA, and ensuring fidelity of data analysis and diagnostic tests is challenging. Such problems are especially acute for emerging / novel diseases that lack thoroughly

System And Method For Monitoring Ultraviolet Radiation Bioremediation

NIST Inventors
Yaw S. Obeng
Healthcare-associated infections (HAIs) impose great burdens on public health; they are probably some of the toughest and the most pressing healthcare problems in acute-care hospitalization. Ultraviolet-C illumination effectively decontaminate surfaces to reduce the population of many HAI-inducing

Timing-Based Computer Architecture Systems And Methods

NIST Inventors
Advait Madhavan , Mark D. Stiles and Matthew Daniels
Tropical algebra is an emerging field of mathematics concerned with graph theory, control theory, and certain optimization problems, especially in discrete event systems. We developed a novel computer circuit called a tropical state machine that uses signal timing and the physics of nanodevices to

Wireless Fire Hose Flow Rate Apparatus And Measuring Flow Rate In A Fire Hose

NIST Inventors
Gregory W. Vogl , Wai Cheong Tam and Christopher U Brown
A wireless sensor network was used to measure water-flow rate in a fire hose. An accelerometer was chosen as the sensor to measure the flow rate based on the vibrations generated by water flowing through a fire hose close to the hose nozzle. These sensors are small, lightweight, and can attach to
