Theoretical physicist Farokh Mivehvar has delved into the intricate interaction of atoms emitting light inside a quantum cavity, a device consisting of two high-quality mirrors facing each other to confine light within a small area for an extended period. This research explores the phenomenon of superradiance, a surprising and striking occurrence in quantum optics where
Computing technology has come a long way since its inception in the 1960s. However, the fundamental principles behind how computers process information have remained relatively unchanged. That is until now. Engineers at the University of Pennsylvania have developed a groundbreaking chip that utilizes light waves instead of electricity to perform complex mathematical computations essential to
The interior of black holes remains an enigma, challenging the boundaries of our scientific understanding. The concept of a singularity, where space and time cease to exist, proposed by physicist Karl Schwarzschild in 1916, seems to defy the laws of physics as we know them. This conundrum has hindered the exploration of black holes until
The field of quantum mechanics has long been limited by the difficulty of observing and controlling quantum phenomena at room temperature. Traditionally, these observations required extremely low temperatures to detect quantum effects. However, a groundbreaking study led by Tobias J. Kippenberg and Nils Johan Engelsen at EPFL has achieved a significant breakthrough in this area.

Grain shape is playing a crucial but underestimated role in the behavior of granular systems, as discovered by researchers at the University of Rochester. In a recent publication in the Proceedings of the National Academy of Sciences, the team led by Rachel Glade, an assistant professor of Earth and environmental sciences and of mechanical engineering,
Quantum physicists and engineers have been striving to develop innovative quantum communication systems over the past few decades. These systems serve as testbeds to evaluate and advance communication protocols. Recently, researchers at the University of Chicago introduced a new quantum communication testbed with remote superconducting nodes and successfully demonstrated bidirectional multiphoton communication on this testbed.
Quantum information technology heavily relies on the use of qubits implemented with single photons. In order to accurately utilize these qubits, it is essential to determine the number of photons involved. Photon-number-resolving detectors (PNRDs) are crucial for achieving this accuracy, providing two main performance indicators: resolving fidelity and dynamic range. Superconducting nanostrip single-photon detectors, or
Cornell University quantum researchers have made a groundbreaking discovery in the field of materials science by detecting and characterizing a previously elusive phase of matter known as the Bragg glass phase. This achievement has settled a long-standing question regarding the existence of this state in real materials. By harnessing the power of large volumes of
