Rigetti's 84-qubit Ankaa-3 System. Credit Rigetti Computing Rigetti Computing has launched its latest quantum computer, the 84-qubit Ankaa-3, marking a significant milestone in superconducting quantum computing. Featuring a broad hardware redesign, the Ankaa-3 system achieves a 99.5% median two-qubit gate fidelity. It introduces technological advancements such as enhanced cryogenic hardware, optimized qubit circuit layouts, and precision control enabled by Rigetti’s novel Alternating-Bias Assisted Annealing (ABAA) technique. The system supports high-performance iSWAP gates with a median gate time of 72 nanoseconds and fSim gates optimized for algorithms like random circuit sampling. These improvements stem from innovations across Rigetti’s technology stack, including advanced [...]

Quantum chips with shuttle tracks (picture above) can be manufactured industrially on 200 mm silicon wafers.Credit:: Jülich Research Center The Jülich Research Center has partnered with ARQUE Systems to integrate a cutting-edge quantum computer into the Jülich Unified Infrastructure for Quantum Computing (JUNIQ) at the Jülich Supercomputing Center (JSC) in 2025. The system features a 5-qubit semiconductor-based quantum processor designed for scalability, potentially expanding to hundreds of qubits in the future. ARQUE's approach leverages transistor-like semiconductor qubits that encode information in the electron spin. This technology benefits from existing semiconductor manufacturing techniques, enabling industrial-scale production on 200 mm silicon wafers. The [...]

Planckian, a quantum technology innovator based in Pisa, Italy, has introduced a new superconducting quantum chip architecture designed to address the critical wiring challenges impeding quantum computer scalability. This “conveyor-belt” architecture employs shared control lines to manipulate qubits, significantly reducing cabling complexity and operational overhead. The design builds upon Planckian’s prior research, including the June 2024 paper, “A Globally Driven Superconducting Quantum Computing Architecture”, which outlined an initial approach to leveraging ZZ coupling for global qubit control. The latest blueprint extends this work by reducing the number of physical qubits required while enabling advanced multi-qubit operations, including the three-qubit Toffoli gate, [...]

MITRE and Montana State University (MSU) are jointly addressing U.S. dependence on Chinese sources for rare earth elements critical to quantum technologies. Through artificial intelligence and density functional theory, they aim to catalog alternative materials that can reduce reliance on imports. Their research particularly targets holmium copper, a key material in quantum cryocoolers currently dominated by Chinese supply chains. Formalized in August 2024, this partnership supports U.S. critical mineral supply chain resilience and technological self-reliance. Additionally, the collaboration involves advancing material science for quantum applications and engaging with federal initiatives, such as the Headwaters Tech Hub and the annual Critical Resource [...]
