Infleqtion, the world’s leading quantum information company, today announced the world’s first demonstration of a materials science application powered by logical qubits. Leveraging the NVIDIA CUDA-Q platform, the demonstration, conducted in collaboration with the University of Chicago and the University of Wisconsin, achieved a 6x boost in application-level computational accuracy. This marks a transformative step forward in quantum computing and showcasing the technology’s potential to tackle otherwise intractable computational challenges, such as the design of next-generation materials.

Together, AQT, d-fine and Fraunhofer AISEC have won a project with the BSI to investigate the “Advanced Security Analysis of Quantum Machine Learning (QML)”. The partners combine deep expertise in quantum hardware (AQT), quantum machine learning (d-fine and Fraunhofer AISEC) and its security aspects (d-fine and Fraunhofer AISEC).

Advancing scalable solid-state quantum computing from materials to quantum processors and simulators—this is the ambitious project goal of the joint European project SPINUS. During their annual meeting, which took place in February in Trento, Italy, the project partners gathered to assess their latest scientific achievements and to align on strategic objectives for the upcoming project phases. During two days of intensive discussions, including a quantum technologies networking session with external participants, the consortium showcased decisive milestones and lived up to SPINUS’ role in advancing European quantum research.

The University of Oxford research group led by OQC CSO Dr. Peter Leek today announced research demonstrating a fundamental speedup of the controlled-Z gate in superconducting qubits reaching a fidelity of 99.8% in only 25 ns.

IonQ, a leader in the quantum computing and networking industries, today announced a significant milestone in the development of high-speed, mixed-species quantum logic gates for trapped-ion quantum computing and networking. The findings further the company’s momentum in driving scalable, high-fidelity quantum networking and distributed quantum computing. Detailed in a new paper written by IonQ scientists and co-authored with Australian National University, the research shows a novel approach to achieving an orders-of-magnitude increase in physical gate speed of two-qubit gates between different atomic species.

University of Arizona College of Engineering researchers Christos Gagatsos and Bane Vasic received two grants from the federal government to advance novel areas in quantum information. Gagatsos was awarded $1.4 million from the U.S. Army Research Office to investigate the application of quantum error correction in magnetic field sensing, and Vasic was awarded $600,000 from the National Science Foundation to stabilize quantum computing with error correction codes.

Pritzker Molecular Engineering researchers entangled two physically separate resonators.

The research group led by Prof. Yunfei Pu and Prof. Luming Duan from Tsinghua’s Institute for Interdisciplinary Information Sciences has recently achieved multiplexing-enhanced generation of heralded atom-photon quantum entanglement over a 12 km fiber with a cold atom quantum repeater node. This work breaks several world records for metropolitan-scale (>10 km) quantum network.

Quantum Source, a company developing technology for powerful, cost-effective, practical photonic quantum computers, today announced its pilot engagement with QC Design’s Plaquette, a state-of-the-art software tool for designing and optimizing fault-tolerant quantum computing architectures. This collaboration will boost Quantum Source’s capabilities to rigorously simulate, analyze, and refine the photonic fault-tolerance architectures integral to its proprietary large-scale quantum computing platform.

Sandia National Laboratories and the University of New Mexico have for the first time demonstrated a practical way to detect these “leakage errors” for neutral atom platforms. This achievement removes a major roadblock for one branch of quantum computing, bringing scientists closer to realizing the technology’s full potential. Many experts believe quantum computers will help reveal truths about the universe that are impossible to glean with current technology.
