PhD student (m/f/d) in the field of quantum technology with a focus on the development of low-outgassing vacuum systems (21-225-QUEST)

Physikalisch-Technische Bundesanstalt (QUEST / QVLS-Q1)

The Physikalisch-Technische Bundesanstalt (PTB) is the national metrology institute of the Federal Republic of Germany with scientific and technical service tasks and promotes progress and reliability in metrology for society, industry and science.
The research association “Quantum Valley Lower Saxony-Q1” (QVLS-Q1), a cooperation of Leibniz Universität Hannover, TU Braunschweig and PTB, has set itself the goal of developing a 50-qubit quantum computer based on trapped ions.
Within the framework of this project, a temporary position is available at PTB Braunschweig, Hanover, for
3 years at the earliest possible date:
Doctoral student (m/f/d) in the field of quantum technology
with a focus on the development of low-outgassing vacuum systems
Remuneration group 13 TVöD Bund (85%) ○ limited term
Your tasks:
Quantum control via trapped ions is one of the most advanced approaches to develop a fault-tolerant programmable quantum computer. Based on ion trap chip technology with microwave near-field control, a 50-qubit system will be built. All aspects from chip design and fabrication with integrated optics and electronics, laser and electronics development to the various software layers and applications will be covered.
Your activities in our project are:
Planning of vacuum systems for testing the outgassing behaviour of different materials
Planning, execution and evaluation of outgassing tests
Construction of a test apparatus for the comparison and further development of outgassing strategies in combination with UV irradiation to minimise the residual gas pressure in vacuum systems
Planning, implementation and evaluation of measurement campaigns to characterise bake-out processes
Development of additively manufactured vacuum chambers
Your profile:
Very good university degree (master’s/diploma) in physics or a related discipline
Knowledge in vacuum and clean room technology or related fields
Knowledge of part of the fields of laser technology, optics, electronics, construction is an advantage
Interest and aptitude for developing and conducting vacuum experiments
High level of commitment, ability to work independently and willingness to learn
Strong teamwork and communication skills
Very good knowledge of German and English (written and spoken)
Physical ability to work in the lab and conduct experiments at external sites must be available
We offer:
Research in a leading group in the field
Intensive PhD supervision by an interdisciplinary team
Excellent national and international networking, in addition to QVLS-Q1 the research group is e.g. involved in the Cluster of Excellence “QuantumFrontiers”.
World-leading research institution with excellent infrastructure
Payment in accordance with the German Federal Public Service Collective Agreement (TVöD Bund) including annual bonus and capital-forming benefits.
