Podcast with Jonathan Reiner, Director of Product Solutions, Quantum Machines
A Conversation with Jonathan Reiner, Director of Product Solutions at Quantum Machines
Jonathan Reiner, Director of Product Solutions at Quantum Machines, sat down with Yuval Boger to discuss the rising complexity of quantum control, customer trends toward fidelity, low-latency compute, and automated calibration. As a condensed-matter physicist turned product manager, Reiner shares insights on scaling control electronics, the skills needed to operate quantum computers, and his preference for spin qubits.
From Condensed-Matter Physics to Quantum Control
Reiner's journey began at the Weizmann Institute, where he graduated as a condensed-matter physicist. He worked on topological materials, laying the groundwork for his future work in quantum computing. After completing his studies, Reiner relocated to Sydney to join the group of Professor Michelle Simmons at Silicon Quantum Computing. There, he worked on silicon-28 and phosphorus atoms in silicon, developing quantum computing devices.
In 2022, Reiner decided to return to Israel and joined Quantum Machines as a product manager. Since then, he has led the Product Solutions team, addressing customer problems and challenges. Reiner notes that the complexity of quantum control has increased significantly, requiring a multidisciplinary approach to master mechanical engineering, analog front-end design, logic design, and software development.
The Double-Edged Complexity of Quantum Control
Reiner describes the challenge of double-edged complexity, where the product itself is complicated, and the market complexity comes from different qubit modalities. Quantum Machines is trying to serve various qubit platforms, including spin qubits, superconducting qubits, and AMO. To handle this complexity, the company created two teams: product managers with a technical orientation and physicists who represent the customer side within QM.
Scaling to a Million Qubits
Reiner acknowledges that building truly useful quantum computers will require a million qubits, which is a significant challenge. However, he notes that this might not be necessary if the right type of qubits are chosen. Quantum Machines is working on reducing the physical-to-logical overhead, and Reiner believes that the control side will contribute to this reduction.
Operating a Quantum Computer
Reiner emphasizes that operating a quantum computer requires strong physicists who understand qubit physics. They should also be good programmers and familiar with amplifiers, filters, and other system components. Depending on the facility, hands-on experimentalist skills may be necessary. Reiner is a big fan of spin qubits, which he believes are a promising modality.
IP Protection
Reiner acknowledges that IP protection is a sensitive issue, especially when working with customers. Quantum Machines is working hard to set firm standards, ensuring that customer-facing people are not working with competitors and providing software features that allow customers to classify and protect content.
A Conversation with Seth Lloyd
Reiner would love to have dinner with Seth Lloyd, a physicist who asks fundamental questions about the limits of quantum computing. Lloyd's work on the Hamiltonian of the universe and the physical limits of quantum computers fascinates Reiner. He believes that a conversation with Lloyd would be a fun and enlightening experience.
Conclusion
Jonathan Reiner's conversation with Yuval Boger provides valuable insights into the challenges and opportunities of quantum control. As the Director of Product Solutions at Quantum Machines, Reiner is at the forefront of this rapidly evolving field. His expertise and enthusiasm are contagious, and his commitment to pushing the boundaries of what is possible is inspiring. As we continue to explore the possibilities of quantum computing, Reiner's work will be an essential part of the journey.
