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, further enhancing scalability.
MIT Professor Seth Lloyd praised the architecture as “simple and elegant,” highlighting its potential for scalable, fault-tolerant quantum computing using current superconducting technologies. Planckian’s Chief Scientific Officer, Marco Polini, emphasized the design’s scalability and its ability to mitigate costs and thermal noise, positioning it as a practical solution to quantum hardware challenges.
Founded in 2023 as a spin-off from the University of Pisa and Scuola Normale Superiore, Planckian aims to revolutionize quantum computing through innovative chip designs that address wiring complexity and scalability by design.
