Columbia Physicists Shine New Light on an Old Quantum Optics Problem About Collective Behavior

“Calculations from Ana Asenjo-Garcia and Stuart Masson reveal that any atom array is capable of bursting—a sign that atoms are syncing up. When atoms interact with each other, they behave as a whole rather than individual entities. That can …

Component for brain-inspired computing

“Researchers from ETH Zurich, the University of Zurich and Empa have developed a new material for an electronic component that can be used in a wider range of applications than its predecessors. Such components will help create electronic circuits that …

Create text animations with Parola Library for Arduino

“Make cool looking text animations/transitions on 8x8 dot matrixes controlled by MAX7219 modules”

Current-Sense Amplifier with Dual Over Current Level Monitor & Alert Output

“The project presented here is a high common-mode current sense amplifier with two high-speed comparators to detect out-of-range current conditions. The comparators are configured to detect and respond to dual over current conditions. These devices feature an adjustable limit threshold …

D-Wave Deploys First United States-Based Advantage Quantum Computer Accessible in the Leap Quantum Cloud Service

“D-Wave Systems Inc. (“the Company”), a leader in quantum computing systems, software, and services, and the only company building both quantum annealing and gate-based quantum computers, today announced the availability of the first Advantage™ quantum computer, accessible via the Leap …

Diamond mirrors for high-powered lasers

“Just about every car, train and plane that’s been built since 1970 has been manufactured using high-power lasers that shoot a continuous beam of light. These lasers are strong enough to cut steel, precise enough to perform surgery, and …

Ditching sensors for streamlined control of microdevices

“A single-actuator system allows sensor-free highly precise position control for microelectromechanical devices. The ability to precisely control the position and movement of miniature devices is being taken into new territory as KAUST scientists develop tinier and simpler devices without a …

EMT Conduit-Mounted Wind Sensors with Arduino

“I present a method to continuously measure wind speed and wind direction as part of a custom weather station project. This article is part of a series discussing methods for adding sensing capabilities to a DIY telescoping pole project made …

Engineers Investigating NASA’s Voyager 1 Telemetry Data

“While the spacecraft continues to return science data and otherwise operate as normal, the mission team is searching for the source of a system data issue. The engineering team with NASA’s Voyager 1 spacecraft is trying to solve a …

Fiber glow brings more go for underwater communications

“Optical fibers doped with perovskite nanocrystals bring new opportunities for photodetectors for high-speed, free-space and underwater data links. In free-space and underwater optical wireless communication systems, there is often a trade-off between the size of a photodetector and its bandwidth …
