Experimental Physicist

Permanent employee, Full-time · Delft

Our mission
QuantWare is the world's leading manufacturer of superconducting quantum hardware. As a high-growth start-up with a global customer base, our mission is to accelerate the advent of the quantum computer. We push the boundaries of what's possible in our field. We work on making the world’s largest quantum processors, as fast as possible. 

At QuantWare, we’re not just producing quantum hardware for the hyperscalers of tomorrow; we’re working on technology that will change the world. To make that ambition a reality, we need exceptional people who drive real impact. That’s where you come in. 

We are looking for a skilled and motivated Experimental Physicist to join our R&D team. In this role, you will contribute to the development of next-generation quantum hardware by researching and designing advanced superconducting circuits. You will work in an international, collaborative environment alongside world-class experts, pushing the boundaries of quantum technology. If you are passionate about solving fundamental challenges in quantum measurement and eager to drive innovation in scalable quantum processors, we’d love to hear from you!
Impact of the role
As an Experimental Physicist in our R&D team, your work will be critical to advancing the scalability and performance of superconducting quantum processors. By developing nonreciprocal superconducting circuits, such as isolators and parametric amplifiers, you will enhance qubit readout accuracy, reduce noise, and improve the overall stability of quantum systems. You will be part of a team advancing cutting-edge quantum technologies by developing the next generation of quantum readout modules and increasing qubit performance through material research. Through close collaboration with experimentalists and device engineers, your research-driven innovations will bridge the gap between theoretical advancements and practical, scalable quantum systems. 

Collaboration is at the core of this role. You will work closely with multidisciplinary teams to integrate experimental results into the quantum device design cycle, directly influencing the development of next-generation quantum hardware. Your contributions will be essential in meeting our technical and product milestones, ensuring QuantWare remains at the forefront of quantum computing innovation.
What you'll be doing

  • Design and conduct device characterization experiments, aiming to advance quantum hardware in terms of performance and scalability, including
    • noise properties, gain, bandwidth, and isolation.
    • Increase qubit performance through material research, increasing coherence and 2q gate performance through reduced TLS losses.
    • Develop and optimize measurement protocols for nonreciprocal superconducting circuits, including isolators, and parametric amplifiers.
  • Analyze and interpret experimental data, identifying key trends to guide further development of superconducting quantum technologies.
  • Contribute to the development of high-fidelity qubit readout modules, integrating parametric amplifiers, isolators and other on-chip circuit components.
  • Collaborate with multidisciplinary teams to integrate experimental results into quantum device design cycles.
What we offer

You’ll be part of a high performing team of world-leading experts at the forefront of quantum technology on a mission to change the world. QuantWare offers a fast-paced environment where you can excel and become the best version of yourself, where you can shape and own your role, taking on significant responsibility from day one.

  • An excellent monthly salary depending on experience and holiday pay (a bonus of 8% of your annual salary, paid out once a year in May)

  • A very solid pension scheme (20% off your annual salary, minus the statutory offset, of which QuantWare contributes 63%). On top of that, we fully pay for your  partner’s and orphan’s pension plus disability premium waiver. For a secure future for you and your loved ones.

  • We believe in giving and taking ownership, that’s why we let you decide on when and how to get your work done - as long as it gets done (i.e. through an open vacation policy, flexible working hours and hybrid working options).

  • For international colleagues we provide support with relocation to the Netherlands, tailored to your personal circumstances (e.g. visa application, travel costs, temporary housing and support in applying for a 30% tax benefit);

  • Great extra benefits: the choice between a public transport business card or travel allowance, a development budget based on personal ambitions and need and plenty of social and health initiatives (such as team outings, chair massages and sports classes).

Your profile

While we understand the perfect candidate might not exist, if you check most of the boxes below, we’d love to hear from you:

  • MSc in Physics, Electrical Engineering, or a related field, or equivalent practical experience (bonus points for a Phd)

  • Research experience in quantum systems or cryogenic measurements (2+ years in Industry or Academia) 

  • Experience in Python programming for experiment automation

  • Experience in operating superconducting circuits or similar quantum systems

  • Knowledge of nonreciprocal superconducting circuits / parametric amplifiers / advanced readout techniques are considered a strong plus.

  • Familiarity with microwave engineering / noise reduction / thermalization techniques for quantum devices are a strong plus 


If you’re excited about this opportunity and recognise yourself in most of the points above, we’d love to hear from you!
