Researchers have successfully operated an 18-qubit modular array in germanium, a significant milestone in the development of utility-scale quantum computing1. This achievement demonstrates the feasibility of integrating and operating a large-scale qubit register, a crucial component of quantum computing architectures. Semiconductor spin qubits, such as those used in this experiment, are a leading candidate for building hybrid quantum-classical systems due to their potential for integration and scalability. The simultaneous operation of 18 qubits marks a notable breakthrough in overcoming the challenges of scaling spin-qubit systems while maintaining performance and control. This advancement has significant implications for the field of quantum computing, as it brings us closer to realizing the potential of quantum systems for complex computations and simulations. The success of this experiment matters to practitioners because it underscores the rapid progress being made in quantum computing, which will ultimately require significant updates to cryptographic systems and protocols.
