Quantum System Architect

Permanent employee, Full-time · Delft

Your mission
Qblox is looking for a quantum system architect to help us design the next-generation control stacks for quantum computers and quantum networks. These quantum control stacks generate the analog signals needed for the control and readout of quantum bits. The signals have frequencies spanning the range from DC to the microwave regime and need to have extremely low noise, temperature drift and interference. To reach these analog properties as well as stringent timing criteria in quantum computing, signals are generated using networks of high-end FPGAs connected to high-speed data converters. To generate the sequence of required pulses, we designed implemented the Q1, a classical CPU with a custom instruction set that is able to operate in a hard real-time fashion with nanosecond precision. On top of this hardware stack we run a software stack that is responsible of taking user defined quantum circuits and compile them to the Q1ASM, our assembly language that can be executed on the Q1 processor.

Our products are used by world leading research institutes and companies around the globe in their effort to build industrial scale quantum computers. As a quantum system architect, it is your responsibility to help design the next generation of products and features, aimed to operate quantum computers in operational HPC environments. Next to this, we expect you to design optimal integrations between various technical domains. You will work closely with the other system architects, roadmap leaders and various engineering teams to guarantee that the system will be engineered according to the architecture you specify. Lastly, you will play an important role in the process of protecting our inventions using patents by identifying innovative ideas and (co-)writing patent applications.
