Researchers at the CUNY ASRC and at Florida International University report in the journal Science their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits. Based on this approach, they outline opportunities that advance fundamental understanding of wave-matter interactions and usher wave-based technologies into a new era.

Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with Stanford University and the University of California – Berkeley, have developed an on-chip twisted moiré photonic crystal sensor that uses MEMS technology to control the gap and angle between the crystal layers in real time. The sensor can detect and collect detailed polarization and wavelength information simultaneously.

Groundbreaking research by physicists at The City College of New York is being credited for a novel discovery regarding the interaction of electronic excitations via spin waves. The finding by the Laboratory for Nano and Micro Photonics (LaNMP) team headed by physicist Vinod Menon could open the door to future technologies and advanced applications such as optical modulators, all-optical logic gates, and quantum transducers. The work is reported in the journal Nature Materials.

Until now, creating quantum superpositions of ultra-cold atoms has been a real headache, too slow to be realistic in the laboratory. Researchers at the University of Liège have now developed an innovative new approach combining geometry and "quantum control", which drastically speeds up the process, paving the way for practical applications in quantum technologies.

Philip Kurian, a theoretical physicist and founding director of the Quantum Biology Laboratory (QBL) at Howard University in Washington, D.C., has used the laws of quantum mechanics, which Schrödinger postulated, and the QBL’s discovery of cytoskeletal filaments exhibiting quantum optical features, to set a drastically revised upper bound on the computational capacity of carbon-based life in the entire history of Earth. Published in Science Advances, Kurian’s latest work conjectures a relationship between this information-processing limit and that of all matter in the observable universe.

Kenneth Merz, PhD, of Cleveland Clinic's Center for Computational Life Sciences, and a research team are testing quantum computing’s abilities in chemistry through integrating machine learning and quantum circuits.

A new study led by Associate Professor Dong Zhaogang from the Singapore University of Technology and Design (SUTD) has found a way to achieve substantial wavelength tuning at ambient conditions using tiny, tunable nanostructures and low-voltage electrical control. This discovery is published in Advanced Materials in a paper titled, “Electrically tunable and modulated perovskite quantum emitters via surface-enhanced Landau damping”.

An international team led by Rutgers University-New Brunswick researchers has merged two lab-synthesized materials into a synthetic quantum structure once thought impossible to exist and produced an exotic structure expected to provide insights that could lead to new materials at the core of quantum computing.

A team of researchers from U of T Engineering has discovered hidden multi-dimensional side channels in existing quantum communication protocols.

Now, researchers in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) are doubling down, literally, on metasurface technology by creating a bilayer metasurface, made of not one, but two stacked layers of titanium dioxide nanostructures. Under a microscope, the new device looks like a dense array of stepped skyscrapers.
