Quantum Information Architect

About Quantum Brilliance

Quantum Brilliance is the world leader in room-temperature quantum computing using synthetic diamonds. Our unique vision is to make quantum computing available as an everyday technology, from data centres to remote and mobile systems like autonomous robots and satellites. In contrast to quantum computers that fill a room, we are developing quantum accelerators with more compute power than a classical supercomputer but in a form factor smaller than a lunchbox.

Founded in 2019 by leaders in diamond quantum science from the Australian National University, we are a full-stack quantum computing company. An Australia-German company, our HQs are in Canberra and Stuttgart, with additional locations across eastern Australia and southern Germany. We are working with global technology leaders to develop quantum computing applications, integrate quantum with high-performance computing, solve materials science challenges and develop ultra-precise semiconductor manufacturing and quantum control techniques. We are backed by leading venture capital funds and major research and technology institutes.

The Mission

The Quantum Information Architect [QIA] is a central and decisive role to define the architecture and requirements of the future generations of our integrated quantum devices and align these with the overall digital-based quantum computing system architecture. The QIA defines the necessary designs and requirements to translate logical quantum circuits to native HW gates and the diamond quantum processor layout to operate these native gates in a most efficient and performant way.

The QIA drives the theoretical analysis and simulation activities behind the design and development of our integrated quantum devices, and interacts strongly with our quantum engineering teams that develop fast and efficient control, initialisation and readout methods of NV spin systems on a physical level, as well as the SW application team developing quantum algorithms.

About the Role

Responsibilities include:

• Designing innovative quantum architectures to efficiently run logical gates and circuits on a NV-based information processing platform.

• Defining, and verifying through modelling, the requirements for the quantum (qubit characteristics, qubit connectivity, architecture symmetries) and system control (temporal and frequency response times and resolutions, amplitudes and dynamic range) hardware, to be suitable for a targeted application/use-case.

• The modelling of the performance of QB’s quantum devices (e.g., gate and measurement fidelity, noise, error, and cross-talk characterizations) and develop strategies to achieve optimal performance.

• Identify and design symmetries in NV-based quantum architectures towards the simplification of the quantum circuits for enabling algorithm optimization.

• Craft experiments based on NV centres in diamonds, contribute to our growth targets by scaling the number of qubits, testing and simulating new qubit architectures, and exploring new control and readout technologies.

• Work closely within an cross-functional team of quantum engineers, device designers and developers, solution and system architects.

• Supporting the growth ambitions of Quantum Brilliance by helping others to gain technical expertise.
