PhD scholarship in Continuous Variable Quantum Computing, Sensing and Communication

Technical University of Denmark (DTU)

2800 Kgs. Lyngby, Denmark

DTU Physics has available numerous PhD positions in the field of continuous variable quantum computing, quantum sensing and quantum communication. The positions and the projects will be a part of the Center of Excellence, “Center for Macroscopic Quantum States – bigQ” supported by the Danish National Research Foundation.

Quantum computing represents a new paradigm for information processing as it allows for solution to problems that are intractable on conventional computers. One particular platform for quantum computing is light where quantum information is encoded into the continuous variables (CV) of the field. We have recently produced the “substrate” – a multipartite entangled state – for a CV quantum computer: The offered PhD project will advance the system to the next level, demonstrating simple quantum computer gates, considering scalability and developing error correction techniques.

Quantum sensing: Using non-classical states of light, it is possible to measure different parameters and fields with unprecedented precision that goes beyond what is possible with classical technologies. One prominent example is the measurement of Gravitational waves from outer space using non-classical light in very large interferometers. In this project, the student will develop new quantum measurement techniques and combine it with squeezed and CV entangled light to largely improve the sensing of different parameters. Fundamental measurement concepts will be tested and novel applications (e.g. quantum-enhanced microscopes for the measurements of biological system) will be developed.

Quantum communication is the art of transmitting quantum states between nodes in a communication network. It can be used for ultra-secure communication or for connecting quantum computers. To realize fault-tolerant and long-distance quantum communication, the quantum states must be protected against noise and decoherence. This is done using different error-correcting schemes. In this project, we will realize an error-correcting scheme using CV entangled states of light with the aim of transmitting quantum states through a network with an efficiency that is higher than what is attainable by direct transmission.

Who are we?
We are a research group at the Technical University of Denmark (DTU) studying quantum information processing, quantum communication and quantum sensing based on quantum optics, quantum optomechanics and diamond physics. Our vision is to generate macroscopic states of light, mechanics and spins to test quantum physics in new regimes and to interrogate disruptive new applications of sensing and information processing. Our main focus is basic research but we also strongly encourage and support innovation and industry partnerships.

Our group comprises around 45 people including Faculty members, PhD students, postdocs, engineers and an administrator.

Who are we looking for?
We are looking for an exceptional physicist, scientist and engineer with an extraordinary talent and an outstanding drive. We are in particular looking for a person with academic excellence and/or with a demonstrated outstanding scientific achievement. We also expect that you have an exceptional ability of developing new ideas. What matters the most is your internal drive to make significant and groundbreaking progress.

Responsibilities and tasks
You will carry out an ambitious research project in a team effort within the Center for Macroscopic Quantum States. You will supervise students during the project and build things that work.

Candidates should have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.

What do we expect?

  • You are excited about large challenges, and you very much enjoy solving them.
  • You have an extraordinary drive towards achieving groundbreaking results.
  • You enjoy working in a team with an open minded spirit. You are excited to teach and learn from other group members.
  • You love to discuss physics and to participate in thoughtful conversations.
  • You make things work and deliver!

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and appointment terms
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 3 years.

The work will take place at the DTU campus in Lyngby.
