Researchers at the Indian Institute of Science (IISc), Bangalore, have have integrated two-dimensional (2D) semiconductor colloidal quantum wells (CQWs) with dielectric metasurface resonators (MSRs) to achieve unprecedented emission line narrowing and long- range photon transport at room temperature for on-chip photonic quantum information processing.

The Fraunhofer Institute for Applied Optics and Precision Engineering IOF is presenting a new photon source at SPIE Photonics West in San Francisco (January 28 to 30, 2025) that has been specially developed for the "Prepare-and-Measure" protocol of quantum communication. The components of the source are optimized for use in space.

Quantum Computing Inc. ("QCi" or the "Company"), an innovative, integrated photonics and quantum optics technology company, today announced that it has entered into securities purchase agreements with institutional investors for the purchase and sale of 8,163,266 shares of common stock in a private placement at a purchase price of $12.25 per share. The offering is expected to result in gross proceeds of $100 million, before deducting offering expenses. The closing of the offering is expected to occur on or about January 9, 2025, subject to the satisfaction of customary closing conditions.

In a new paper in Nature Photonics, researchers at the University of Pennsylvania School of Engineering and Applied Science (Penn Engineering) describe the creation of a novel photonic switch that overcomes this size-speed tradeoff. And at just 85 by 85 micrometers, the new switch’s units are smaller than a grain of salt.

Now, a team of researchers from IESL FORTH, Dr. Theocharis Lamprou and Dr. Paraskevas Tzallas, and ICFO, Dr. Javier Rivera-Dean, Philipp Stammer and ICREA Prof. Maciej Lewenstein, has successfully addressed both issues. They created generalized coherent state superpositions (GCSS), verified their quantum nature and employed them to drive a nonlinear optical process (which, per se, is indicative of the high photon number and intensity of the states). Their findings, demonstrated both theoretically and experimentally, have been reported in Physical Review Letters.

Quantum Computing Inc. (“QCi” or the “Company”), an innovative, integrated photonics and quantum optics technology company, today announced the receipt of its third and fourth purchase orders for its thin film lithium niobate (TFLN) photonic chip foundry. The orders, received from a renowned European technical university and a Canadian photonic integrated circuit (PIC) design house, mark a key milestone in the QCi Foundry Pilot Launch Program.

ICFO researchers Dr. Frederic Català-Castro, Santiago Ortiz-Vázquez, Dr. Carmen Martínez-Fernández, Martín Fernández-Campo, Dr. Neus Sanfeliu-Cerdán, led by Prof. Dr. Michael Krieg, along with Dr. Paolo-Antonio Frigeri from Impetux Optics and collaborators from multiple institutes (Center of Genomic Regulation, Institute for Research in Biomedicine and Universitat Pompeu Fabra), have developed a novel optical tweezer method to characterize rheological properties. This approach, published in Nature Nanotechnology, allows for more versatile, simplified measurements of the rheological properties of cells, tissues, and organelles, improving upon previous techniques.

In quantum technology applications such as quantum computing, light plays a central role in encoding and transmitting information. NTU researchers have recently made breakthroughs in manipulating light that could potentially usher in the era of quantum computing.
