PhD Postion Photonic Circuits for Quantum Computer

We have an open PhD position at TU Delft in the exciting new area of a large-scale photonic circuits for quantum computer. While quantum computer based on spins in diamond connected with photonic circuits is promising for the scalability, their realization poses a host of new engineering challenges, which we strive to address!

Specifically, the candidate is expected to focus on the development of on-chip large-scale photonic circuits integrated with colour centres in diamond as essential parts of the lower stack levels of the quantum computing engines.

Optical switch and other on-chip optical components will be designed, fabricated in a cleanroom and characterized. The layer will be integrated with diamond cavity having colour centres and electrical circuits using cryo-CMOS. The qubits are optically coupled and controlled on-chip and inside a cryostat and the fidelity of the basic quantum operation will be characterized.

The student has an opportunity to closely collaborate with QuTech and TU Delft experimentalists and theorists who are actively developing this hardware on campus.

Job requirements

  • You have a master’s degree in microelectronics, photonics, electrical engineering, applied physics, or comparable discipline at the time of taking on the position. Prior course in photonics and/or experience in nanofabrication inside a cleanroom will be highly appreciated. While a prior course in quantum information is a plus, no prior knowledge in this is required.
  • You enjoy working in a team and bring excellent organizational, communication and interpersonal skills.

Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the Graduate School’s Admission Requirements.

Employment conditions

Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts: an initial 1,5 year contract with an official go/no go progress assessment within 15 months, followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2541 per month in the first year to € 3247  in the fourth year. As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment with an excellent team of supervisors, academic staff and a mentor. The Doctoral Education Programme is aimed at developing your transferable, discipline-related and research skills.

The TU Delft offers a customisable compensation package, discounts on health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. For international applicants we offer the Coming to Delft Service and Partner Career Advice to assist you with your relocation.


Quantum Computer & Engineering in Delft

The mission of Quantum and Computer Engineering (QCE) is to invent, design, prototype, and demonstrate the potential of disruptive computing engines by harnessing unique features of emerging devices (e.g. qubits, memristors, spintronics, and graphene). Building such computing engines requires a full-stack interdisciplinary approach, encompassing fabrication and operation of qubits, electronic circuit design, micro-architecture, programming models, compilers, and simulator platforms.

QCE’s research encompasses a broad range of applications, integrating multiple layers of the stack: the computing and network architecture (including AI-oriented architectures, quantum architectures, neuromorphic architectures, computation-in-memory architectures, big-data architectures, and secure architectures), the interface to the technology (Cryo-CMOS circuit design, memristive-based and graphene-based circuit design, and test and reliability of integrated circuits), and related programming and support flow (compilers, mapping tools, and simulators).

To make quantum computing a reality, the Quantum and Computer Engineering department, in collaboration with QuTech is working intensively on developing, designing and prototyping scalable quantum computing engines based on different quantum technologies, such as superconducting qubits, spin-based qubits, colour-centres in diamond, and topological qubits.
