RWTH Aachen - II. Physikalisches Institut/Quantum Technology Group

Quan­tum Tech­no­lo­gies Group (RWTH Aachen) con­ducts rese­arch in semi­con­duc­tor spin-qubits and SQUID spec­tro­scopy. It addres­ses issues of opti­mi­za­tion of indi­vi­dual spin qubits in GaAs and Si and their sca­la­bi­lity. It tack­les pro­blems in mate­ri­als, device fabri­ca­tion, qubit con­trol elec­tro­nics and auto­ma­tion. Peter Grün­berg Insti­tute 9 (For­schungs­zen­trum Jülich) con­ducts rese­arch in mate­ri­als and devices for future infor­ma­tion tech­no­lo­gies inclu­ding quan­tum com­pu­ta­tion, neu­ro­mor­phic com­pu­ta­tion. The mate­rial base inclu­des semi­con­duc­tor hete­ro­st­ruc­tures (III-Vs, II-Vis, Si-Ge-Sn) and nano­st­ruc­tures (nano­wires and quan­tum dots) as well as 3-dimen­sio­nal topo­lo­gi­cal insu­la­tors and phase change mate­ri­als. The state-of-the-art mate­rial growth and depo­si­tion tech­ni­ques that are avail­able in the insti­tute are fun­da­men­tal to the deve­lop­ment of high qua­lity devices as nee­ded for the future infor­ma­tion tech­no­lo­gies.

Quan­tum Tech­no­lo­gies Group (RWTH Aachen) con­ducts rese­arch in semi­con­duc­tor spin-qubits and SQUID spec­tro­scopy. It addres­ses issues of opti­mi­za­tion of indi­vi­dual spin qubits in GaAs and Si and their sca­la­bi­lity.

Require­ments:

App­li­cants must have a doc­to­rate/Ph.D. or equi­va­lent.
Cur­r­ently, in col­la­bo­ra­tion bet­ween the two insti­tu­tes, we are loo­king to recruit a post­doc­to­ral rese­ar­cher to deve­lop opti­cal inter­face devices to sin­glet-triplet qubits in gate defi­ned quan­tum dots in III-V hete­ro­st­ruc­tures. High fide­lity quan­tum state trans­fer bet­ween spins and pho­tons is nee­ded for quan­tum net­works, with clus­ter quan­tum com­pu­ting or quan­tum com­mu­ni­ca­tion being examp­les of such net­works. This col­la­bo­ra­tion is a part of a lar­ger effort in the quan­tum com­pu­ting pro­gram of the For­schungs­zen­trum Jülich and the clus­ter of excel­lence ML4Q.

App­li­ca­ti­ons are invi­ted from indi­vi­du­als who are inte­rested in con­tri­bu­ting to the deve­lop­ment of opti­cal inter­face devices and algo­rithms for the quan­tum state trans­fer bet­ween a pho­ton and the sin­glet-triplet qubit. The selec­ted can­di­date is expec­ted to focus their rese­arch on one or more of the fol­lo­wing areas:
  • Cha­rac­te­ri­za­tion of the per­for­mance of the sin­glet-triplet qubit with an epi­ta­xial quan­tum dot ser­ving as a pho­ton qubit recei­ver in its pro­xi­mity.
  • Cha­rac­te­ri­za­tion of the spin-pho­ton con­ver­sion in the epi­ta­xial quan­tum dots in the device.
  • Con­trol­ling the spin trans­fer bet­ween the quan­tum dots in the device.
  • Design and exe­cu­tion of pro­to­cols for the ope­ra­tion of the device.
  • Design of devices and their fabri­ca­tion.

App­li­ca­tion are wel­come from indi­vi­du­als who have:
  • A PhD in Phy­sics or Engi­nee­ring Sci­en­ces with focus on quan­tum tech­no­lo­gies.
  • Expe­ri­ence in elec­tri­cal and/or opti­cal cha­rac­te­ri­za­tion of devices.
  • Expe­ri­ence in the design and exe­cu­tion of expe­ri­ments (hard­ware and ide­ally also soft­ware).

What we of­fer:

The posi­tion is 2 years and is to be fil­led as soon as pos­si­ble. This is a full-time posi­tion. It is also avail­able as part-time employ­ment per request.

The salary cor­re­sponds to level EG 13 TV-L.

RWTH Aachen Uni­ver­sity is cer­ti­fied as a "Family-Fri­endly Uni­ver­sity". We wel­come app­li­ca­ti­ons from all sui­ta­bly qua­li­fied can­di­da­tes regard­less of gen­der. We par­ti­cu­larly wel­come and encou­rage app­li­ca­ti­ons from women, dis­ab­led per­sons and eth­nic mino­rity groups, reco­gni­zing they are under­re­p­re­sen­ted across RWTH Aachen Uni­ver­sity. The princi­ples of fair and open com­pe­ti­tion apply and appoint­ments will be made on merit. RWTH Aachen is an equal oppor­tu­nities employer. We the­re­fore ask you not to include a photo in your app­li­ca­tion.
