QuTech and Fujitsu have recently announced a partnership to develop a blueprint for a scalable quantum computer. This collaboration is centered around delivering a comprehensive framework for building quantum computers that addresses all major components required for scalability and reliability. According to the announcement, the partnership takes a “full-stack approach,” which encompasses everything from physical qubit modules to high-level error-correction algorithms designed to stabilize quantum computations. At the foundation of this blueprint are high-quality qubits with extended coherence times—vital for maintaining quantum states over longer computations—and optical connections between qubit modules, which support scalability by allowing individual modules to communicate seamlessly. This design is expected to lay the groundwork for building increasingly complex quantum systems as quantum technology advances. The project comprises several specialized layers, each tackling distinct parts of the quantum computing stack. At the top layer, quantum algorithms and error correction play a central role, counteracting the inherent instability of qubits through error-correction codes. These codes are designed to maintain the integrity of quantum states, enabling complex problem-solving capabilities that could outperform classical systems in specific applications. Beneath the algorithmic layer lies the micro-architecture, responsible for translating quantum computational logic into fine-grain digital control signals for the electronic interface. This functional abstraction provides an essential bridge, allowing the quantum instructions and error-correction codes to be communicated precisely to the quantum hardware.
