“The goal is to make all these parts work together effectively on a single platform, which would greatly reduce the loss of signals and remove the need for extra technology,” said Quinlan. “Phase one of this project was to show that all these individual pieces work together. Phase two is putting them together on the chip,” he added.

A team of researchers from several prestigious institutions helped NIST with this amazing achievement. These included the University of Colorado Boulder, the NASA Jet Propulsion Laboratory, the California Institute of Technology, the University of California Santa Barbara, the University of Virginia, and Yale University.

“I like to compare our research to a construction project. There are a lot of moving parts, and you need to make sure everyone is coordinated so the plumber and electrician show up at the right time in the project,” said Quinlan. We all work together really well to keep things moving forward,” he added.

A team of researchers at Cornell University has created a semiconductor chip that will allow ever-tinier devices to function at the higher frequencies required for the next generation of 6G communication technology.

In addition to requiring more bandwidth at higher frequencies, the next generation of wireless communication also demands more time. According to researchers, the new semiconductor provides the appropriate time delay to prevent signals from dissolving at a single point in space after being relayed over numerous arrays.

Researchers observe the quantum coherence of a quintet state with four electron spins in molecular systems for the first time at room temperature.

In a study published in Science Advances, a group of researchers led by Associate Professor Nobuhiro Yanai from Kyushu University’s Faculty of Engineering, in collaboration with Associate Professor Kiyoshi Miyata from Kyushu University and Professor Yasuhiro Kobori of Kobe University, reports that they have achieved quantum coherence at room temperature: the ability of a quantum system to maintain a well-defined state over time without getting affected by surrounding disturbances.

This breakthrough was made possible by embedding a chromophore, a dye molecule that absorbs light and emits color, in a metal-organic framework, or MOF, a nanoporous crystalline material composed of metal ions and organic ligands.

A team of Stony Brook University physicists and their collaborators have taken a significant step toward the building of a quantum internet testbed by demonstrating a foundational quantum network measurement that employs room-temperature quantum memories. Their findings are described in a paper published in the Nature journal Quantum Information.

Research with quantum computing and quantum networks is taking place around the world in the hopes of developing a quantum internet, a network of quantum computers, sensors, and communication devices that will create, process, and transmit quantum states and entanglement. It is anticipated to enhance society’s internet system and provide certain services and securities that the current internet does not have.

The field of quantum information combines aspects of physics, mathematics, and classical computing to use quantum mechanics to solve complex problems much faster than classical computing and to transmit information in an unhackable manner. While the vision of a quantum internet system is growing and the field has seen a surge in interest from researchers and the public at large, accompanied by a steep increase in the capital invested, an actual quantum internet prototype has not been built.
