Researchers at the College of Design and Engineering (CDE) at the National University of Singapore (NUS) have developed a supramolecular co-assembly platform that produces chiral soft materials with strong and stable full-color circularly polarized luminescence (CPL) across the visible spectrum, including in red, which has historically been a difficult target.

Using new techniques, Yale researchers have demonstrated the ability to use lasers to cool quantized vibrations of sound within massive objects to their quantum ground state, the lowest energy allowable by quantum mechanics. This breakthrough could benefit communications, quantum computing, and other applications. The results are published in Nature Physics.

The reliable engineering of quantum states, particularly those involving several particles, is central to the development of various quantum technologies, including quantum computers, sensors and communication systems. These collective quantum states include so-called Dicke and Greenberger-Horne-Zeilinger (GHZ) states, multipartite entangled states that can be leveraged to collect precise measurements, to correct errors made by quantum […]
