Everyone who ever took a photo knows the problem: if you want a detailed image, you need a lot of light. In microscopy, however, too much light is often harmful to the sample—for example, when […]

A team of scientists has revealed how a single quantum device can accurately measure the three fundamental units of electricity—the ampere (unit of electrical current), the volt (unit of electrical potential) and the ohm (unit […]
A team of Johns Hopkins engineers has developed a new, more powerful method to observe molecular vibrations, an advance that could have far-reaching implications for early disease detection. Click to rate this post! [Total: 0 […]
There are high hopes for quantum computers: they are supposed to perform specific calculations much faster than current supercomputers and, therefore, solve scientific and practical problems that are insurmountable for ordinary computers. The centerpiece of […]
Researchers at NPL have reported a novel high-speed charge sensing method for ballistic electrons, a potentially useful technique in the fields of electron quantum optics, quantum electrical metrology, flying qubit technology, and signal sensing. Click […]
Topological quantum systems are physical systems exhibiting properties that depend on the overall connectivity of their underlying lattice, as opposed to local interactions and their microscopic structure. Predicting the evolution of these systems over time […]
Researchers at Rice University and collaborating institutions have discovered direct evidence of active flat electronic bands in a kagome superconductor. This breakthrough could pave the way for new methods to design quantum materials—including superconductors, topological […]
A plucked guitar string can vibrate for seconds before falling silent. A playground swing, emptied of its passenger, will gradually come to rest. These are what physicists call “damped harmonic oscillators” and are well understood […]
Scientists have turned a longstanding challenge in electronics—material defects—into a quantum-enhanced solution, paving the way for new-generation ultra-low-power spintronic devices. Spintronics, short for “spin electronics,” is a field of technology that aims to go beyond […]
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 […]
