Planckian, a quantum technology innovator based in Pisa, Italy, has unveiled a new superconducting quantum chip architecture designed to address the critical wiring challenges that hamper the scalability of quantum computers. This “conveyor belt” architecture uses shared control lines to manipulate qubits, significantly reducing wiring complexity and operational overhead.
The draft builds on Planckian's previous research, including the June 2024 paper. “A globally advanced superconducting quantum computer architecture”which outlined a first approach to using ZZ coupling for global qubit control. The latest draft extends this work by reducing the number of physical qubits required while enabling advanced multi-qubit operations, including the three-qubit Toffoli gate, further improving scalability.
MIT professor Seth Lloyd praised the architecture as “simple and elegant” and highlighted its potential for scalable, fault-tolerant quantum computing using current superconducting technologies. Marco Polini, Planckian's chief scientific officer, emphasized the design's scalability and its ability to reduce cost 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 the Scuola Normale Superiore, Planckian aims to revolutionize quantum computing through innovative chip designs that take into account wiring complexity and scalability by design.
Further technical details can be found in the documents: “A globally advanced superconducting quantum computer architecture” (June 2024) and “Conveyor belt superconducting quantum computer” (December 2024). You can find more insights on her blog here.
