IFW Dres­den e.V. - Solid State and Mater­i­als Rese­arch

The Leib­niz Insti­tute for Solid State and Mater­i­als Rese­arch Dres­den e. V. (IFW Dres­den) con­ducts mod­ern mater­i­als rese­arch on a sci­ent­i­fic basis for the devel­op­ment of new and sus­tain­able mater­i­als and tech­nolo-gies. The insti­tute employs an aver­age of 500 people from over 40 nati­ons and, in addi­tion to its sci­ent­i­fic tasks, is ded­ic­ated to pro­mot­ing young sci­ent­ists and engin­eers.

Doc­toral Rese­ar­cher Pos­i­tion (m/f/d)


Quantum met­ro­logy using optic­ally address­able quantum dot spin qubits

Working field:

“Devel­op­ment of a quantum met­ro­logy exper­i­ment using optic­ally
act­ive quantum dot spin qubits of GaAs quantum dots”


The Insti­tute for Integ­rat­ive Nanos­ciences (IIN), Leib­niz IFW Dresden e.V. is one of the world lead­ers in the domain of semi­con­ductor quantum light sources and provided pion­eer­ing con­tri­bu­tions to the design, fabri-cation and char­ac­ter­iz­a­tion of self-assembled quantum dots. Quantum dots are a prom­ising plat­form for the real­iz­a­tion of devices of the quantum inter­net, such as sources of entangled photon sources, quantum re-peat­ers and one-way quantum com­put­ing. In order to real­ize these devices, high qual­ity droplet etched GaAs quantum dots with spe­cific prop­er­ties are used. Recently, we have demon­strated single source en-tan­gle­ment swap­ping and GHz-clocked emis­sion using our lead­ing quantum dot-based entan­gle­ment pho-ton sources. We aim to deepen and diver­sify the invest­ig­a­tions of quantum dot-based quantum inform­a­tion sys­tems and there­fore offer a PhD pos­i­tion on the topic:

“Devel­op­ment of a quantum met­ro­logy exper­i­ment using optic­ally
act­ive quantum dot spin qubits of GaAs quantum dots”

Your pro­file: We are look­ing for a highly motiv­ated and team-ori­ented stu­dent (m/f/d), who holds a mas­ter`s degree in phys­ics. Basic know­ledge of optics, quantum sys­tems, stat­ist­ics, com­pu­ta­tional data ana­lysis is desired. Addi­tion­ally, a basic under­stand­ing of solid-state phys­ics and semi­con­ductor sys­tems would be bene­fi­cial. The suc­cess­ful can­did­ate (m/f/d) should be inter­ested in fun­da­mental sci­ences and should enjoy prac­tical work. Very good com­mu­nic­a­tion skills in writ­ten and spoken Eng­lish are required.

What we offer:

Pro­ject descrip­tion: The suc­cess­ful PhD can­did­ate (m/f/d) will be respons­ible for the devel­op­ment of a quantum met­ro­logy exper­i­ment using mul­tiple entangled photon sources in the con­text of a quantum net-work test­bed. For this pur­pose, the can­did­ate (m/f/d) will need to design, build and val­id­ate a quantum op-tics inter­fer­ence exper­i­ment in cooper­a­tion with external aca­demic and industry part­ners. Con­sequently, the exper­i­ment will need to be integ­rated into the test­bed. Once estab­lished the can­did­ate (m/f/d) will be re-spons­ible to run the exper­i­ment and pub­lish on the res­ults. The can­did­ate (m/f/d) will join the "Solid-State Quantum Photon­ics" team of Dr. Cas­par Hop­f­mann and will be able to develop his/her skills as a young sci­ent­ist (m/f/d). The act­ive par­ti­cip­a­tion of the can­did­ate (m/f/d) in internal and external con­fer­ences, work-shops and sem­inars is expli­citly desired.

Con­di­tions: The employ­ment rela­tion­ship, includ­ing remu­ner­a­tion, is based on the fed­eral pub­lic employ-ment stand­ard (TV-L) accord­ing to pay group 13. We offer a weekly work­ing time of 26 hours (65%). For excep­tion­ally well qual­i­fied can­did­ates (m/f/d) an up to a 100% (40 hours) con­tract may be pos­sible. The employ­ment is ini­tially lim­ited to 1 year, an exten­sion for another 2 years is pos­sible.

The IFW would like to increase the num­ber of women in the sci­entific field. Qual­i­fied women are there­fore expli­citly invited to apply. Severely dis­abled applic­ants (m/f/d) will be given pref­er­en­tial con­sid­er­a­tion in case of equal suit­ab­il­ity and qual­i­fic­a­tion.

How to apply:

Please send your applic­a­tion with inform­at­ive doc­u­ments (let­ter of motiv­a­tion, cur­riculum vitae, proof of edu­ca­tion, ref­er­ences, etc.) by Septem­ber 30, 2022, exclus­ively in elec­tronic form and in a PDF file (other formats will not be con­sidered), quot­ing the ref­er­ence num­ber 055-22-4320 to:
