Postdoc Positions in Quantum Network Systems and Applications

Join Prof. Dr. Stephanie Wehner 's group and work at the forefront of Quantum Technologies.

The vision of a Quantum Internet is to provide fundamentally new internet technology by enabling quantum communication between any two points on earth. Such a Quantum Internet will – in synergy with the 'classical' Internet that we have today - connect quantum processors in order to achieve unparalleled capabilities that are provably impossible using only classical communication.

Two postdoc positions are available in the group of Prof. Dr. Stephanie Wehner at QuTech, Delft University of Technology. The group's mission is to push the boundaries of quantum network technology through quantum computer science research, working alongside academic and industrial partners to develop the core technologies that will make remote entanglement available to all.

Join us and apply for one of the two available PostDoc positions below

1. Quantum Network Applications

The goal of this position is to explore new applications and use cases for quantum networks. The successful candidate is motivated by the challenge of making quantum networks useful for society, and thrives on engaging with diverse academic and/or industrial fields to uncover impactful applications. The ideal candidate is able to lead the direction of this research, shaping the application domains we explore based on their interests and vision for where quantum networks can make a difference.

The successful applicant has an excellent track record in quantum technologies, and a PhD in the field at the time of assuming the position.

1. Quantum Network Systems

Our team has built QNodeOS, the world's first operating system for quantum network nodes. This position advances that work—developing advanced quantum software systems needed to run applications on emerging quantum networks. The ideal candidate is able to develop research directions in this nascent field, as part of our group's mission to bring quantum networks to society.

The successful candidate has an excellent track record in computer science, computer engineering, or related fields, with an emphasis on software systems. They are a systems builder at heart, thriving on hands-on experimentation with real software systems, with the possibility to access real-world quantum network hardware. Prior expertise in operating systems is desirable. Prior knowledge in quantum technologies is a plus, but not required.

General

Both positions offer significant opportunities for developing leadership skills—through proposing and supervising Master's student projects, co-supervising PhD candidates, managing research projects, and contributing to the day-to-day running of the group. We are looking for tomorrow's faculty members, research leaders, and entrepreneurs—and are committed to helping you become one.

• You have a PhD degree in computer science, computer engineering, mathematics or physics or comparable discipline at the time of taking on the position. See details in the specific positions above.
• You have an excellent track record of research.
• You enjoy working in a multi-disciplinary team and bring excellent organizational, communication and interpersonal skills.
