Project description

Third-cycle subject: quantum communication with nanoscale devices to generate and detect single photons

Quantum technology offers unprecedented possibilities for entirely new schemes for computation, communication and sensing, holding great promise for drastic improvements in performance and functionality, showing disruptive potential with profound impact on society, markets and everyday life. Quantum optics lies at the heart of these new developments as photons are ideal carriers of quantum information due to high-speed and low-noise propagation. Within this project, we aim at the development of quantum devices for the generation, manipulation and detection of light at the single photon level with high efficiency. The devices will be implemented in real-world applications to demonstrate and assess the advantages of quantum devices. You will develop quantum devices using thin film deposition techniques, electron beam lithography as well as etching and metalization tools. The devices will be characterized and operated in customized optical setups based on cryostats using quantum optics techniques. You will be involved in several international collaborations including research groups in Taiwan and the European Union.

Supervision: V. Zwiller is proposed to supervise the doctoral student. Decisions are made on admission

  • Admission requirements

    To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:

  • passed a second cycle degree (for example a master's degree), or
  • completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
  • acquired, in some other way within or outside the country, substantially equivalent knowledge
  • have a master of science in Physics or Electrical engineering with specialization in optics, photonics, nanoscience or quantum mechanics
  • have lab experience with optical measurements at the single photon level
  • In addition to the above, there is also a mandatory requirement for English equivalent to English B/6, read more here


    In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

  • independently pursue his or her work
  • collaborate with others,
  • have a professional approach and
  • analyse and work with complex issues.
  • In addition to the traditional academic merits, a relevant degree project, international experience is a plus.
  • Interest and experience in nanofabrication.
  • Knowledge and experience with quantum technologies.
  • Knowledge and experience in high speed electronics or microwave engineering.
  • Knowledge and experience with cryogenic systems.
  • After the qualification requirements, great emphasis will be placed on personal competency.

    Target degree: Doctoral degree

    Information regarding admission and employment

    Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years ' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time.
