The paper presents a method to scale quantum computing using error-mitigated dynamic circuits and circuit-cutting techniques. Current quantum hardware is noisy, has limited qubit connectivity, and can only store information for a short time. To overcome these limitations, the authors employ dynamic circuits, where quantum gates can be classically controlled by mid-circuit measurements, and circuit-cutting to create periodic connectivity across multiple quantum processing units (QPUs). They demonstrate this approach by creating a quantum state with 142 qubits spanning multiple QPUs, connected in real-time via a classical link. The dynamic circuits enhance qubit connectivity and the instruction set, making quantum computers more versatile. The paper also discusses the implementation of long-range gates using virtual Bell pairs and the suppression of errors in dynamic circuits through zero-noise extrapolation and staggered dynamical decoupling. The authors benchmark their methods against hardware-native benchmarks, showing high-quality results. The work highlights the potential of modular quantum computing architectures and the importance of error mitigation and dynamic control for scaling quantum computers.The paper presents a method to scale quantum computing using error-mitigated dynamic circuits and circuit-cutting techniques.
