Quantum sensor can detect electromagnetic signals of any frequency

Researchers at MIT developed a method to enable quantum sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. Quantum sensors detect the most minute variations in magnetic or electrical fields, but until now they have only been capable of detecting a few specific frequencies, limiting their usefulness. Quantum […]

TR12 centers in diamond as a room temperature atomic scale vector magnetometer

Extending the field of quantum metrology i.e., magnetometry, electrometry, and thermometry to the atomic scale requires robust sensors with high sensitivity and spatial resolution. Optically addressable spins in diamond are excellent candidates as they often come with outstanding stability and narrow transitions, facilitating high sensitivity and nanometer resolution. The Nitrogen-Vacancy (NV) center has already proven […]

Nano particle trapped between mirrors works as a quantum sensor

Researchers are now demonstrating how nanoparticles in tiny optical resonators can be transferred into quantum regime and used as high-precision sensors. The team has proposed a new concept for a high-precision quantum sensor. The researchers suggest that the motional fluctuations of a nanoparticle trapped in a microscopic optical resonator could be reduced significantly below the […]

The side effects of quantum error correction and how to cope with them

It is well established that quantum error correction can improve the performance of quantum sensors. But new theory work cautions that, unexpectedly, the approach can also give rise to inaccurate and misleading results — and shows how to rectify these shortcomings. Quantum systems can interact with one another and with their surroundings in ways that […]
