AMD chips help Quantum Machines control qubits with nanosecond precision

Controlling qubits demands electronics that react with nanosecond precision, a feat now bolstered by AMD technologies integrated throughout Quantum Machines’ Hybrid Control architecture. The company isn’t solely focused on the qubit itself, but the classical computing infrastructure needed to orchestrate it. “The control electronics must act on qubits with nanosecond precision before their quantum states decohere,” says Ethan Baratz, Senior Product Manager at Quantum Machines. From real-time pulse processing to large-scale quantum error correction, AMD hardware is helping bridge the gap between ultra-fast control and complex computation, enabling a system where different workloads run on the resources best suited to them. AMD Versal Devices Enable Nanosecond-Scale Real-Time Pulse Processing AMD Versal devices are central to achieving real-time pulse processing within Quantum Machines’ hybrid control architecture, enabling operations measured in hundreds of nanoseconds. This capability focuses on maintaining deterministic timing as data flows between classical and quantum processing layers, a critical factor in sustaining qubit coherence. Quantum Machines utilizes AMD adaptive computing devices to support these nanosecond-level feedback operations inside the quantum runtime, a key component for precise qubit control. AMD EPYC processors further extend this infrastructure by providing the server-side compute power necessary for complex classical processing tasks, complementing the speed of the Versal devices. This tiered approach addresses the challenge of orchestrating data movement across the entire quantum stack, ensuring the quantum processor receives information precisely when required. The integration spans multiple layers, from immediate pulse shaping to large-scale quantum error correction decoding and optimization, demonstrating a partnership beyond simple component supply. Fault-tolerant quantum computing demands sustained gate fidelity across trillions of operations, requiring continuous error detection, decoding, and correction. AMD’s 2026-06-20 report indicates Alveo accelerators can boost quantum simulation performance by up to 30x, a capability that directly supports this continuous error mitigation.

Hybrid Control Architecture Orchestrates Varied Classical Workloads Quantum Machines distributes computational load across specialized hardware to optimize performance, mirroring approaches common in classical computing applications. This tiered architecture recognizes that not all quantum operations demand the same resources; some benefit from execution within the controller itself, while others are better suited to external accelerators and high-performance servers. This division of labor is critical, as hundreds of nanoseconds represent the timeframe within which many kinds of classical computation must happen simultaneously alongside quantum processes. The partnership with AMD facilitates this complex orchestration by integrating its technologies across multiple layers of the Hybrid Control architecture. Looking ahead to systems with tens of thousands of qubits, the need for heterogeneous computing architectures becomes even more pronounced. The company anticipates that advances across the entire quantum stack, not just qubit development, will be essential for scaling quantum computers. “I’m excited about the day when we have 10,000 or even 100,000 qubits to control,” stated a spokesperson, emphasizing that building scalable quantum computers requires a holistic approach encompassing both quantum hardware and the classical infrastructure supporting it. This infrastructure must be capable of handling a wide variety of workloads across multiple timescales, a challenge AMD’s technologies are designed to address. OPNIC Interconnect Delivers Deterministic, Low-Latency Quantum Communication The OPNIC interconnect establishes a deterministic communication pathway for synchronizing quantum and classical computations, moving beyond conventional Ethernet limitations. This PCIe-based optical interconnect, designed for time-sensitive data transfer, ensures that processing performed on external accelerators aligns precisely with quantum operations, a feat previously hampered by unpredictable network latency. Quantum Machines uses this technology to create a unified system where diverse computational resources operate in concert, addressing a core challenge in scaling quantum processors. AMD Versal devices accelerate larger-scale hybrid workflows, handling tasks like quantum error correction decoding and optimization routines while maintaining deterministic communication with the quantum controller. The company reports that this architecture allows for workloads to span timescales ranging from hundreds of nanoseconds to milliseconds, a necessity for sustaining gate fidelity over trillions of operations. “Data must move seamlessly between different layers of the stack while preserving deterministic timing and ensuring that the quantum processor receives the information it needs exactly when it needs it,” a spokesperson stated, highlighting the importance of synchronized processing. AMD EPYC processors provide the server-side compute infrastructure for complex classical tasks, complementing the specialized acceleration provided by Versal devices.

Quantum Error Correction Demands Extensive Classical Compute Resources Quantum error correction relies on distributing computational load across diverse classical hardware. Not all processing demands are equal; image processing for atom readout, for example, can require milliseconds of processing time, a scale far exceeding the hundreds of nanoseconds available for other critical operations. This disparity necessitates a tiered architecture where specialized resources handle specific tasks, optimizing overall system performance. Quantum Machines integrates AMD technologies across its Hybrid Control architecture to address this challenge, moving beyond simply supplying components to a deeper collaborative effort. This allows for a flexible system where computationally intensive tasks can offload from the controller to external resources, including accelerators and high-performance servers. AMD EPYC processors then provide the server-side infrastructure for even more complex classical processing, supporting workloads spanning hundreds of nanoseconds to milliseconds. “Some computations will happen inside the controller. Others will run on external classical compute resources,” explains the source material, highlighting the distributed nature of modern quantum computing. According to the source, every round of error correction generates information that must be processed and translated into corrective actions, creating a massive classical computing challenge. AMD’s partnership with Quantum Machines aims to make this possible, recognizing that building scalable quantum computers requires not only improved qubits but also the computing architecture to control and orchestrate them.
