It generates quantum entanglement between a microwave resonator and a signal that is emitted toward a target and can theoretically make radar detection up to four times faster in scenarios with comparable signal power and target noise. It also reduces susceptibility to jamming. A microwave quantum radar begins with a stream of entangled visible-frequency photons […]
FAQ
How can quantum sensors and quantum batteries improve electric vehicle operation?
In the near term, quantum sensors are being developed that can more accurately measure EV battery capacity, assess battery safety, and reduce vehicle weight. In the longer term, quantum batteries have been proposed that could dramatically improve the speed and efficiency of battery charging. The energy remaining in an EV battery has been estimated using […]
What are the seven types of quantum sensors?
The seven types of quantum sensors include chemical sensors, clocks, gravimeters, imaging, interferometers, magnetometers, and thermometers. Several types of quantum sensors are already in use, and more are being developed for commercialization. They can be used in a wide variety of applications from earth sciences to molecular biology and wide band gap power semiconductors. Chemical […]
What technologies are used to make quantum sensors?
Quantum sensors rely on quantum mechanical principles like entanglement, interference (also called superposition), discrete quantum states, and coherence. They are unlike quantum computers, which need highly stable environments for operation. Some quantum sensors can operate at room temperature. As a result, quantum computers are still a work in progress, while quantum sensors are used today. […]
What sensors are used to monitor volcanoes?
Monitoring volcanoes is complex, and it’s an important activity to ensure public safety in many areas of the world. It involves monitoring ground deformations, earthquakes and vibrations, volcanic gas, rock and water chemistry, and remote sensing from satellites. Volcano monitoring needs to be implemented on a continuous basis or in near-real-time and is an extreme […]
How do micro photo sensors work and what are they used for?
Micro photo sensors have built-in amplifiers and are available in various configurations, with modulated, non-modulated, and polarized light beams. They provide precise and stable sensing or positioning of materials, components, or assemblies. Some have integrated connectivity, like IO-Link and IP 67 environmental ratings. Uses for micro photo sensors include precision manufacturing equipment in Industry 4.0 […]
What are the key specifications of machine vision sensors?
Charged coupled devices (CCDs) and CMOS active pixel sensors (CMOS sensors) are the primary image sensor technologies. They rely on lenses and other optical components to deliver the image to be captured. This FAQ reviews the differences between CCDs and CMOS sensors, some key specifications of image sensors, the concept of quantum efficiency, and some […]
How many ways are there to measure temperature?
Temperature is the most commonly measured physical quantity. Thermometry, the measurement of temperature, involves a wide range of technologies. Its uses range from maintaining a comfortable and safe environment for people to industrial processes operating at over 3,000 °C and quantum computing operating at near absolute zero. This article reviews some of the more common […]
What are the six microphone polar patterns used for?
Microphone polar patterns, sometimes called pickup patterns, define microphone sensitivity in different directions. The different polar patterns are used for controlling sound pickup and isolating the sound source, or sources, of primary interest from surrounding sources. There are six common microphone polar patterns: cardioid, supercardioid, hypercardioid, omnidirectional, lobar, and bidirectional. Polar patterns are represented by […]
