Job description

Offer DescriptionJob Summary:
The winning candidate will work as a research assistant at the International Centre for
Interfacing Magnetism and Superconductivity with Topological Matter – MagTop of the
Institute of Physics of the Polish Academy of Sciences. The Centre and the junior
postdoctoral researcher position are supported by the MagTop project (FENG.02.01-
IP.05-0028/23) implemented as part of the MAB FENG action of the Foundation for
Polish Science co-financed by the European Union from the 2nd Priority funds of the
Programme European Funds for Smart Economy 2021-2027 (FENG).
The position involves the theoretical implementation and analysis of quantum gates and
small quantum algorithms using topological superconductors formed from chains of
magnetic adatoms connected to conventional (or s-wave) superconductors. Additionally,
the PD will help investigate potential microscopic mechanisms behind the STM-ESR
manipulations of the magnetic adatoms in superconductors.
Job Description:
Background: Magnetic adatoms (such as Fe, Mn, or Co) in s-wave superconductors
(such as Nb, Al, or Rh) provide a viable platform for realising a topological quantum
computer based on Majorana zero modes (MZMs), or Majorana qubits (MQs). However,
manipulating coherently these quantum degrees of freedom in such systems remains an
open challenge, mainly because the system parameters (such as the exchange couplings)
are difficult to control experimentally in real time. Moreover, MQs alone do not provide
a universal set of quantum gates, which limits their utility. We have recently put forward
a new type of quantum bit, a Yu-Shiba-Rusinov qubit (YSRQ), stemming from two
nearby magnetic impurities on a superconductor, which we conjectured that it could
facilitate the implementation of a universal set of quantum gates together with MQs (see
Fig. 1).
Aim: The main goal in this part is to resolve this conjecture by explicitly calculating the
quantum coherent properties of the device in Fig. 1 and beyond. In a first step, the PD
will determine the low-energy Hamiltonian describing the device, and then use it as
input for constructing the necessary set of quantum gates (e.g., the SWAP gate between
the YSRQ and the MQs). He/she will estimate the fidelities of the gates in the presence
of errors in the gate operations, which can be implemented experimentally by rotating
the magnetisation profile in STM-ESR setups, as well as in the presence of
environmental degrees of freedom, such as phonons, magnons, and low-energy
quasiparticles. For that, the PD will establish the density matrix that describes the
dissipative dynamics of the hybrid qubits system, and complement the analytical
calculations with numerical simulation using QuTiP: The Quantum Toolbox in Python.
Once this task is completed, we will explore networks of such hybrids, and develop small scale quantum algorithms,
such as Deutsch-Jozsa. The outcome, could have far reaching implications in the design of quantum devices out of magnetic
adatoms in superconductors, in particular whether a functioning quantum processor is pertinent in current or near-future
experiments.
Requirements:
– A PhD degree in Physics or in related fields, such as e.g., condensed matter theory
and/or quantum information theory held for no longer than five years, is required,
– Knowledge of machine learning approaches will be an asset,
– Experience in the theory of open quantum systems will be an asset,
– Experience in using various programming languages (especially Python and
Mathematica) will be an asset,
– Very good knowledge of written and spoken English is required.

longer than five years. The period of five years is counted from the year of obtaining the
doctoral degree.

of a person with longer experience very well suited to the tasks of the project) for a
maximum period of 57 months (with all employee benefits and an additional medical
insurance package) with a gross salary of PLN 11 200 per month, which is
