Engineers at Caltech have achieved a significant milestone in quantum communication by demonstrating a quantum network with two nodes, each containing multiple qubits. The team developed a novel protocol for entanglement multiplexing, enabling parallel quantum information transmission using ytterbium atoms embedded in yttrium orthovanadate (YVO4) crystals. This approach overcomes the bottleneck of sequential qubit preparation and photon transmission, significantly boosting communication rates. The system leverages the unique optical properties of ytterbium atoms, which emit photons entangled with their quantum states. By fine-tuning lasers to target specific atoms and applying a quantum feed-forward control protocol, the researchers successfully generated entangled states between pairs of atoms despite differences in their optical frequencies.

Mitsubishi Electric Corporation has signed a joint research agreement with Quantinuum K.K., Keio University, SoftBank Corp., Mitsui & Co., Ltd., Yokohama National University, and LQUOM, Inc. to develop scalable and deployable quantum information processing technologies. The collaboration aims to connect multiple quantum computers and classical systems, addressing challenges such as limited processing capacity and service disruptions. Key focus areas include quantum memory, quantum repeaters, high-efficiency transducers for converting quantum states to photons, subsystems for stabilizing transmission paths, and control systems for quantum computers. The research will target intra-site and inter-city quantum connections, leveraging quantum entanglement and photon-based communication to enable long-distance quantum information transfer. Quantum repeaters will mitigate photon [...]

Diagram of the Logical Qubits as Implemented in the Ocelot chip with a Phase-Flip Error Shown in the Middle Cat Data Qubit Amazon Web Services (AWS) has introduced Ocelot, its first-generation quantum computing chip, designed to significantly reduce the costs of quantum error correction by up to 90%. Developed at the AWS Center for Quantum Computing at the California Institute of Technology, Ocelot uses a scalable, hardware-efficient architecture to address one of the most critical challenges in quantum computing: error correction. The chip employs cat qubits, a type of qubit technology that intrinsically suppresses certain errors, simplifying the error correction process. Quantum error correction is essential for [...]

IonQ has announced its Q4 and full year 2024 financial results. A quick summary of some key financial metrics comparing Q4 2024 versus Q3 2024 and the year ago quarter of Q4 2023 as well as a comparison of full year 2024 versus 2023 is shown in the chart below. Company executives called 2024 IonQ's best year ever and believes that 2025 will be a great year for them too. The company beat their previous revenue expectations for both Q4 and the full year 2024. They also slightly beat their previous expectations for full year 2024 books. Although the company's 2024 net [...]

Turkcell, Turkey’s leading telecommunications provider, and ID Quantique, a global leader in quantum-safe security, have successfully demonstrated the world’s first intercontinental Quantum Key Distribution (QKD) over a fiber-optic link in Istanbul, a city that is located on two continents, Europe and Asia since it straddles the Bosporus Strait. QKD uses quantum mechanics to generate unbreakable encryption keys, ensuring secure communication by detecting any interception attempts. This achievement validates the feasibility of deploying QKD in live telecommunications networks, addressing the growing need for quantum-resistant security as data volumes and connectivity demands increase. The collaboration utilized ID Quantique’s Clavis XG and Clarion KX platforms, which were integrated into Turkcell’s infrastructure. [...]

Q-CTRL has partnered with ELTECH Consulting, a Bangalore-based firm, to expand access to its quantum education and error correction tools in India. ELTECH will serve as an authorized re-seller of Q-CTRL’s Black Opal and Fire Opal software, which are designed to prepare enterprises, researchers, and educators for quantum computing. Black Opal is an interactive quantum education platform, while Fire Opal optimizes quantum algorithms and mitigates errors, addressing critical challenges in current quantum hardware. This collaboration builds on Q-CTRL’s previous initiative with Quantum AI Global, which integrated Black Opal into Tamil Nadu’s technical universities. Tamil Nadu became the first state globally to mandate quantum computing education, incorporating Q-CTRL’s software into [...]
