OFFER DESCRIPTION

Context. One of the most ambitious technological goals is the development of materials for devices working under the laws of quantum mechanics.[1] Among others, an important challenge to be resolved on the way to such breakthrough technology concerns the scalability of the available Hilbert space of the employed quantum registers. Recently, proof-of-principle experiments were reported, in which the implementation of quantum algorithms (the Grover’s search algorithms, iSWAP-gate. etc.) [2,3] in a single-molecule nuclear spin qudit (with d = 4, with d being the dimension of the Hilbert space) known as 159TbPc2 was described, whereby the nuclear spins of lanthanides are used as a quantum register to execute simple quantum algorithms. Importantly, in molecules as SMMs the dimension of the available Hilbert space can be linearly and exponentially scaled by synthetic protocols, whereby the qudit dimension “d” is expressed by synthesizing lanthanide isotope metal complexes as quantum computing hardware.[4] The synthesis of multinuclear large-Hilbert space complexes has to be carried out under strict control of the nuclear spin degree of freedom leading to so-called isotopologues, where the electronic coupling between several nuclear spin units will exponentially extend the Hilbert space available as quantum register. Towards this goal, the detailed understanding of the hyperfine interaction in different lanthanide isotope molecules is of central importance to achieve an exponentially scalable Hilbert space enabling high-performance quantum computing.

Eligibility criteria and requirements

We are looking for a highly motivated candidate (preferably a Rank holder) with a master degree in chemistry or chemical-physics (preferably with maths and physics as allied subjects at the bachelor degree level) from premier universities. The candidate for this PhD project must have a strong background in inorganic synthesis. Experience in molecular magnetism, structural and magnetic characterization (x-ray diffraction, SQUID magnetometer, etc.), and NLO photochemistry is welcome. candidate will have to collaborate crossborder and intersectionally with partners doing the solid state physics, the computational modeling and proficiency in English are required.

 

QUSTEC programme follows MSCA eligibility criteria:

    Level of experience is ‘Early Stage Researcher’, according to the definition in the work programme of the 2018-2020 Marie Skłodowska-Curie actions: Applicants must be, at the date of the respective call deadline of QUSTEC, in the first four years (full-time equivalent research experience) of their research careers and not yet have been awarded a doctoral degree.

    Mobility criterion: The applicants must not have resided or carried out their main activity (work, studies, etc.) in the country of the future host organisation for more than 12 months in the 3 years immediately before the call deadline of QUSTEC. Short stays such as holidays are not taken into account. For refugees under the Geneva Convention, the refugee procedure (i.e. before refugee status is conferred) will not be counted as period of residence/activity in the country of the host organisation.
