Quantum Circuits is now part of D-Wave. Its product positioning is a full-stack quantum development platform for “trusted quantum computing.” Built around the Aqumen Seeker dual-rail cavity superconducting qubit QPU, Aqumen Cloud Service, AquSim simulator, Aqumen SDK, and Quantum APIs, it allows developers to write, simulate, execute, and monitor quantum programs in the cloud.
The platform’s key differentiation lies in hardware-level error awareness. Quantum Error Detection builds error detection directly into the qubit layer; Real-Time Control Flow supports measurement feedback, conditional branching, loops, dynamic gate parameters, real-time reset, and more; Error Detection Handling enables mid-circuit erasure detection, per-qubit terminal measurement, and user-defined post-selection. The simulator comes in two variants: noiseless and DRQ. The former is designed for rapid prototyping, while the latter includes an erasure noise model, QED, and EDH, making it closer to real QPU behavior.
Aqumen SDK is a collection of Python libraries, documentation, and examples. It connects to Aqumen Cloud Service, with jobs monitorable through the cloud portal. QCDL is its high-level programming environment and provides full access to real-time control and error-detection capabilities. The platform also offers a Qiskit Provider, which is suitable for quickly validating existing quantum algorithms, but it does not support RTCF or EDH. CUDA-Q integration targets the NVIDIA quantum programming ecosystem and can run and model workloads on Seeker QPU and AquSim.
The available materials do not disclose any pricing, free tier, billing model, payment methods, or SLA. Deployment appears to be primarily Quantum-as-a-Service, with no self-hosted, private cloud, or on-premises options identified. For documentation, the text mentions SDK docs, examples, CUDA-Q documentation pages, and paper resources, but their completeness cannot be assessed.
Strengths include hardware-level error detection, real-time quantum-classical control, an end-to-end path from simulator to QPU, and compatibility with Qiskit/CUDA-Q. Limitations include opaque commercial information, unknown learning cost for QCDL, and the fact that Qiskit integration cannot access all advanced capabilities. It is better suited to quantum algorithm researchers, university labs, and advanced enterprise R&D teams than to general application developers.
The materials do not provide information on network access, compliance, payment, or local support for China, so availability from China can only be marked as unknown. For similar R&D work in China, users may also evaluate international platforms such as IBM Quantum, Amazon Braket, Azure Quantum, and D-Wave Leap, as well as domestic quantum cloud services as alternatives.
