Recently, a team led by the Laboratoire d’Optique Appliquée (CNRS), in collaboration with ICREA Professor at ICFO Jens Biegert and other multiple institutions (Institut für Quantenoptik - Leibniz Universität Hannover, Fraunhofer Institute for Applied Optics and Precision Engineering IOF, Friedrich-Schiller-University Jena), demonstrated the quantum optical properties of high-harmonic generation in semiconductors. The results, appearing in Physical Review X Quantum, align with the previous theoretical predictions about HHG.

Karlsruhe Institute of Technology Joins IQST as a New Partner.

A team at the Department of Experimental Physics and the Institute of Quantum Optics and Quantum Information (IQOQI) led by Francesca Ferlaino has successfully isolated single atoms of erbium in optical tweezer arrays. This achievement enables a groundbreaking approach to the study of elements with multiple valence electrons —a realm previously dominated by simpler atoms with one or two valence electrons. Erbium, which possesses 14 valence electrons, introduces new degrees of freedom and opens up exciting opportunities for quantum experimentation, enabling the exploration of previously uncharted atomic behaviors.

Quantum Computing Inc. (“QCi” or the “Company”), an innovative, integrated photonics and quantum optics technology company, today announced the Company has received its second purchase order for its thin film lithium niobate (TFLN) photonic chip foundry from the University of Texas at Austin. The order will support the research efforts of the University’s RF Acoustic Microsystem Group and is part of the QCi Foundry’s pilot launch program, with fulfillment expected in Q1 2025.

Quantum Computing Inc. ("QCi" or the "Company"), an innovative, integrated photonics and quantum optics technology company, today announced that it has entered into a securities purchase agreement for the purchase and sale of 16,000,000 shares of common stock at a purchase price of $2.50 per share, priced at-the-market under Nasdaq rules, pursuant to a registered direct offering, resulting in gross proceeds of $40 million, before deducting placement agent commissions and other offering expenses. The closing of the offering is expected to occur on or about November 18, 2024, subject to the satisfaction of customary closing conditions.

A U.S. Naval Research Laboratory (NRL) multi-disciplinary team developed a new paradigm for the control of quantum emitters, providing a new method for modulating and encoding quantum photonic information on a single photon light stream.

Quantum Computing Inc. (“QCi” or the “Company”), an innovative, integrated photonics and quantum optics technology company, today announced that the Company has secured its first order for its thin film lithium niobate (TFLN) photonic chip foundry. The order, placed by a prominent research and technology institute based in Asia, underscores the growing global demand for QCi’s advanced fabrication technology of TFLN and its ability to produce high-performance photonic integrated circuits (PICs) and nanophotonic devices. This milestone highlights QCi’s commitment to accelerating the widespread adoption of TFLN and positioning it as a vital component of the future telecom, datacom, and quantum landscape.

Theorists at the Max Planck Institute of Quantum Optics have made a significant stride in the field of quantum computing. Their research addresses a long-standing question: can quantum computers really outperform classical computers in solving complex problems, despite the presence of errors? In a new study focusing on analogue quantum simulators – specialised quantum devices used to mimic physical systems – the researchers could show precisely that: quantum simulators can remain stable and provide accurate results, even when subjected to errors. This finding is groundbreaking as it suggests that practical quantum advantage, where quantum computers outscore classical ones, may be within reach sooner than previously thought. The work was recently published in Nature Communications.

The rare-earth metal erbium could play a key role in future quantum networks: researchers from MPQ and TU Munich succeeded in spectrally resolving and individually controlling up to 360 erbium ions.

Supersolids are a new form of quantum matter that has only recently been demonstrated. The state of matter can be produced artificially in ultracold, dipolar quantum gases. A team led by Innsbruck physicist Francesca Ferlaino has now demonstrated a missing hallmark of superfluidity, namely the existence of quantized vortices as system’s response to rotation. They have observed tiny quantum vortices in the supersolid, which also behave differently than previously assumed.
