“The research aims to better understand how quantum squeezing can be used in more complicated measurement situations involving the estimation of multiple phases,” said Le. “By figuring out how to achieve the highest level of precision, we can pave the way for new technological breakthroughs in quantum sensing and imaging.”

The study looked at a situation where a three-dimensional magnetic field interacts with an ensemble of identical two-level quantum systems. In ideal cases, the precision of the measurements can be as accurate as theoretically possible. However, earlier research has struggled to explain how this works, especially in real-world situations where only one direction achieves full quantum entanglement.

This research will have broad implications. By making quantum measurements more precise for multiple phases, it could significantly advance various technologies. For example, quantum imaging could produce sharper images, quantum radar could detect objects more accurately, and could become even more precise, improving GPS and other time-sensitive technologies.

In a study published in Engineering, researchers from Nanjing University of Aeronautics and Astronautics and Zhejiang University have unveiled a pioneering approach to designing on-chip computational spectrometers, heralding a new era of high-performance and reliable integrated spectrometers. This innovative inverse-design methodology offers a dramatic leap forward in spectrometer technology, addressing longstanding challenges in performance and reproducibility.

An infographic about the Seven Wonders of the Ancient World — extraordinary architectural and artistic achievements celebrated for their grandeur and innovation. The wonders included the Great Pyramid of Giza, the only surviving wonder, which served as a monumental tomb for the Egyptian Pharaoh Khufu. Although the Hanging Gardens of Babylon’s actual existence and location is debated, they were described as a lush, terraced paradise built in ancient Babylon. The Statue of Zeus at Olympia was a massive gold and ivory representation of the Greek god Zeus, crafted by the sculptor Phidias. The Temple of Artemis at Ephesus was a magnificent sanctuary dedicated to the goddess Artemis, famed for its scale and intricate decoration. The Mausoleum at Halicarnassus was an elaborate tomb for Mausolus, a Persian satrap renowned for its architectural splendor and sculptural detail.
