The field of quantum mechanics has long been restricted to extremely cold temperatures near absolute zero, making it challenging to observe and control quantum phenomena on a larger scale. However, a recent study led by Tobias J. Kippenberg and Nils Johan Engelsen at EPFL has revolutionized this notion. By combining quantum physics and mechanical engineering,

The field of quantum electronics is poised to revolutionize the way we store and transmit information. Unlike traditional electronics which relies on binary digits for memory storage, quantum electronics utilizes qubits to store information. One of the key challenges in quantum electronics has been transmitting quantum information over long distances, beyond just the adjacent quantum
The innovative metasurface technology developed by Penn State electrical engineering researchers is revolutionizing image processing capabilities. Mimicking the natural image processing power of the human eye, this optical element utilizes tiny nanostructures to control light and transform images. Unlike traditional AI systems that require significant computing power and energy, the metasurface preprocesses and transforms images
When it comes to diamonds and other semiconducting materials, defects are often seen as a negative aspect. However, recent research has shown that defects can actually be a quantum sensor’s best friend. These defects, which are essentially irregular arrangements of atoms, can contain electrons with an angular momentum, or spin, that have the ability to
In recent years, quantum physicists and engineers have been striving to develop innovative quantum communication systems that have the potential to revolutionize the field of communication. The University of Chicago researchers have made significant progress in this realm by introducing a new quantum communication testbed with remote superconducting nodes. Their groundbreaking research, published in Physical
Excitons with non-zero momentum have the ability to condense and form charge density waves (CDW), leading to the emergence of excitonic insulators in materials. A recent study conducted by researchers at Shanghai Jiao Tong University and other institutes delved into the possibility of a metal-insulator transition in the atomically thin semi-metallic HfTe2. Their findings, published
In a groundbreaking study published in Nature Physics, Cornell quantum researchers have identified the elusive Bragg glass phase through the use of advanced machine learning data analysis tools and large volumes of X-ray data. This discovery marks a significant milestone in the field of quantum physics, resolving a long-standing debate about the existence of the
Photon-number-resolving detectors (PNRDs) are essential for accurate determination of the number of photons in various quantum systems. Two key performance indicators for PNRDs are resolving fidelity and dynamic range. Superconducting nanostrip single-photon detectors (SNSPDs) are considered the leading technology for single-photon detection due to their high efficiency and speed. However, SNSPD-based PNRDs have faced challenges
The realm of quantum computing has long been praised for its potential to surpass classical computing in terms of both speed and memory utilization. Contrary to classical computers that rely on digital bits (0s and 1s), quantum computers make use of qubits to store quantum information in values between 0 and 1. The ability of
When radiation hits water, it initiates a series of complex reactions that have significant implications, especially in medical settings where X-rays are commonly used. Recent research conducted by a team of theoretical physicists at DESY, in collaboration with colleagues from Argonne National Laboratory, has shed light on the behavior of free electrons in water when
