You will design, measure, and characterize quantum computing hardware as a Josephson Amplifier Specialist. You'll create methods for optimizing quantum processors and will collaborate on a variety of projects that will contribute to IQM's mission of building a quantum computer.

What will I be doing?

• Create and simulate quantum processors with low-error quantum gates and fast, high-fidelity readout for improved performance.
• Superconducting quantum circuit measurement and characterisation, including processor calibration and benchmarking
• Control electronics and cryogenic refrigeration are used in the operation of the quantum processing support infrastructure.
• Design for (quantum part of) readout amplification chain

What skills do I need?

• PhD in circuit QED / Superconducing microwave circuits
• Design of at least some of the following, not just used as part of a measurement setup
  • Wideband near-quantum-limited microwave amplifier, eg. TWPA / IMPA (travelling wave / impedance-matched parameter amplifier)
  • Non-reciprocal parametric devices eg. frequency converter, circulator
• Has seen his/hers designs come out from fab and measured them

What can I expect from IQM?

• A great opportunity to perform world-class R&D and implement cutting-edge technology
• Sufficient financial backing for ambitious projects
• An opportunity to work with a passionate and diverse team on an important mission
• A unique opportunity to make a real impact on the future of quantum
• Growth and progress in a creative and open start-up environment
