Photonic quantum computers hold tremendous promise in terms of speed and efficiency, as they leverage particles of light to process information. However, one of the main challenges faced by researchers is the weak interaction between individual photons, which inhibits the realization of deterministic two-qubit gates essential for scalability. To address this issue, concepts of fusion
Transparent solar cells have the potential to completely transform the landscape of infrastructure by allowing a wide range of surfaces to function as solar panels. This groundbreaking technology opens up a myriad of possibilities for integrating solar power generation into everyday objects. Materials known as non-fullerene acceptors have emerged as a game-changer in the field
Single-photon emitters (SPEs) play a crucial role in the development of quantum technology, serving as microscopic lightbulbs that emit only one photon at a time. These structures are essential for applications such as secure communications and high-resolution imaging. However, many materials containing SPEs are not practical for mass manufacturing due to their high cost and
Quantum physics has always been at the forefront of scientific exploration, delving deeper into the microscopic properties of materials. Recent advancements in analog quantum processors have paved the way for the development of quantum-gas microscopes, offering a powerful tool for understanding quantum systems at the atomic level.

The concept of “coupled oscillations” may not be common knowledge to many, but it plays a crucial role in numerous aspects of nature. These interconnected harmonic oscillators are not limited to describing masses and springs but extend their reach to various scientific and engineering applications. From mechanical systems like bridges to atomic bonds and gravitational
The quest to determine the mass of a neutrino at rest remains one of the most intriguing and elusive challenges in the field of physics. Neutrinos, often referred to as “ghost particles,” play a fundamental role in nature. While they are known to interact weakly with matter, making them incredibly difficult to detect, their significance
When using a microscope to view biological samples, it is important to consider the disturbance that occurs when the lens of the objective is in a different medium than the sample itself. This disturbance can lead to inaccuracies in the measurement of depth, causing the sample to appear flattened. For instance, if a watery sample
Microbiology has always been a field that requires high precision and accuracy when studying samples at the microscopic level. One of the challenges faced in this field is the limited resolution of certain microscopy techniques that hinder the ability to observe structures within living bacteria. Recently, a team at the University of Tokyo has made
In a recent review article published in Reviews of Modern Physics, Fèlix Casanova, along with Prof. Albert Fert, Nobel Prize winner in Physics, and their team, discuss the current state of electrical control of magnetism. Albert Fert, a renowned French physicist, made significant contributions to the field by co-discovering giant magnetoresistance, a groundbreaking effect that
