Doctoral candidate specializing in the field of optical clocks (21-410-QUEST) Wednesday, 23. February 2022

The Physikalisch-Technische Bundesanstalt (PTB) is the national metrology institute of the Federal Republic of Germany with scientific and technical service tasks. It furthers progress and reliability in metrology for society, the economy and science. The QUEST Institute for Experimental Quantum Metrology is a joint institution of Leibniz University Hannover (LUH) and PTB Braunschweig.

 

With a starting date as soon as possible, the QUEST Institute is looking for a candidate to fill the following position at our Braunschweig site for an initial duration of three years:

 

 

Doctoral candidate
specializing in the field of optical clocks

Remuneration Group 13 TVöD Bund (85 %) ○ fixed-term contract

 

 

Your tasks:

In the Quantum Logic Spectroscopy research group, we work on precision spectroscopy of trapped and laser-cooled atomic ions. To this end, we develop quantum computer-inspired techniques for the coherent manipulation of ions and their spectroscopy for applications such as high-precision optical atomic clocks.

Your tasks will include:

  •  Enhancing the Ca+-based multi-ion experiment to attain uncertainty values so far unequalled
  • Implementing and evaluating multi-ion manipulation and cooling techniques
  • Developing and implementing quantum algorithms for ion entanglement to improve the statistical uncertainty
  • Enhancing dynamic decoupling algorithms to suppress environmental effects
  • Developing methods for correlated clock retrieval in close collaboration with the Al+ quantum logic clock
  • Presenting the scientific results at international conferences
  • Participating in international projects such as the TSCAC EU project and the DQ-mat Collaborative Research Center (CRC) 

 

You will find more detailed information about the projects and our job advertisement on our QUEST website.

 

 

Your profile:

  • You have completed your university studies in physics (master’s degree/German Diplom) with a very good degree.
  • You are interested in developing and performing high-precision experiments.
  • You have a high level of commitment, an ability to work independently, and a willingness to learn.
  • You are a strong team player with excellent communication skills.
  • You have a very good command of spoken and written English.
  • Having a good knowledge of atomic physics, quantum optics, laser cooling, laser spectroscopy, or related fields is an advantage.
  • You are willing to travel within Germany and abroad within the scope of your assignment.
  • You must have the physical ability to work in a laboratory and perform experiments at external sites.

 

 

We offer:

  • A position at one of the world’s leading research institutions which has an excellent infrastructure
  • Excellent national and international connections
  • Intensive PhD supervision in an interdisciplinary team as well as practical training in modern experimental technologies of laser and quantum physics and frequency metrology
  • Research leave abroad via our wide-ranging network
  • Remuneration in accordance with the collective bargaining agreement for the public service (Tarifvertrag öffentlicher Dienst Bund – TVöD for the federal level)
  • Good transport connections (bus and bike); free parking
  • In-house daycare center and canteen
