Job description

Position I. Dynamical quantum phase transitions in transmon and fluxonium arrays (Supervisor Associate Professor Matti Silveri)

Quantum computers are yet too noisy for long quantum algorithms. Before full-fledged quantum information tasks, they can be used to implement analog and digital quantum simulations of many-body physics phenomena. This theoretical and computational project aims at boosting realization of dynamical quantum phase transitions in arrays of superconducting quantum devices. Methods are a combination of analytical and numerical many-body physics, quantum information, quantum hardware, and programming on online quantum computers.

The project studies and compares different quantum processor architectures and educates a theoretically and numerically skilled doctor ready to contribute to e.g quantum processor and hardware development in quantum technology industry.

Specific qualifications: Quantum mechanics, scientific computing and condensed matter physics Experience in any of the following is beneficial but not mandatory: quantum information, quantum devices

Position II. In silico platform for quantum simulation of molecular qudits (Supervisor University Researcher Akseli Mansikkamäki)

Single-molecule magnets (SMM) are individual molecules that have a specific electronic structure so that they can be magnetized by an external magnetic field, and they retain this magnetization even after the field is switched off. The quantum-mechanical nature of their magnetic state makes it possible to utilize them as multidimensional computational units – or qudits – in quantum computing. In 2017 a quantum algorithm was implemented in an individual SMM in a proof-of-concept study. Unlike some other technologies used for the realization of quantum computing, the use of molecules is still very much in its infancy. In this project, the doctoral researcher will work to develop a theoretical and computational platform which can be used to study the implementation of quantum algorithms into individual SMMs. The goal is to establish molecular systems as a basis for a new way of building practical quantum computers.

The research takes place at the intersection of physics, chemistry and materials science utilizing methods from all these fields. The specific methods used in the project involve i) quantum-chemical calculations with professional software using high-performance computing to model electronic structure of molecular systems and extended molecular solids; ii) derivation of the necessary working equations used in quantum simulations; and iii) development of a new program code to carry out fully quantum-mechanical simulation of a molecular system under the influence of electromagnetic fields.

Specific qualifications: Good working knowledge of molecular quantum mechanics and some programming skills. Experience in any of the following is preferred but not mandatory: scientific programming, quantum chemistry, density functional theory, command-line usage of Linux, quantum simulation.

Position III. Spin- and photophysics of NV- centres in diamond (Supervisor Professor Juha Vaara)

Nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) are central tools of gaining structural and dynamical information on materials at the microscopic level. With the NV- point defect in diamond it is possible to realise a quantum sensor allowing NMR and EPR of individual nuclear and electron spins both within and outside of the diamond material. In this project we construct and apply a computational multiscale model for the magnetic and optical transitions in the NV- centre, aimed at simulating existing and suggesting novel single-spin NMR and EPR experiments for ultra-sensitive spectroscopy, quantum magnetometry and quantum state control.

The project educates the student in multiscale modelling featuring molecular dynamics simulations of atomic motion in bulk and surface models of diamond, electronic-structure determination of spin Hamiltonians, and spin dynamics simulations of coupled electronic and nuclear spins using these Hamiltonians. The methodology involves density-functional theory (DFT) for atomic dynamics and structure optimisation, correlated ab initio wave function theory for determining the spin Hamiltonians, and Liouvillian spin dynamics governed by the microscopic Zeeman, zero-field splitting and hyperfine interactions, subject to Lindbladian dissipation and with the optical transitions modelled as rapid chemical exchange.

The graduated doctor will be in an excellent position to apply multiscale models in a range of cutting-edge fields from modern biomolecular NMR to quantum optics and fundamental physics. The research is done in collaboration with groups at Algorithmiq Ltd, who will host an industry secondment, as well as University of Eastern Finland.

Specific qualifications: Quantum mechanics, scientific computing, experience in one or more of the following areas: quantum chemistry, spin dynamics, molecular dynamics, reaction kinetics.

Position IV. Cybersecurity of quantum computing technologies (Supervisor Professor Kimmo Halunen)

Cybersecurity is considered an essential property of computers and networked systems. The security of traditional computing platforms has been under development for several decades and although perfect security can never be attained, great progress has been made in this field. Now, the emerging technologies of quantum computing would need to have similar protections and precautions built-in from the beginning.

At the moment, there are several different technologies that enable quantum computing for example based on superconductivity, trapped ions or photonics. There are also quantum annealing based and even analog quantum computers. All these technologies are developed to tap into the powers promised by quantum computing. However, the security properties of these are not really well studied. Thus, the goal of this PhD project is to research the cybersecurity properties (both commonalities and differences) of these different quantum computing architectures.

The graduated doctor will be in an excellent position to apply their understanding of two immensely interesting technologies to pursue career in academia or in industry. The research will be done in collaboration with Assoc. Prof. Matti Silveri in Oulu and also with researchers from University of Jyväskylä. Also industry collaboration is possible through ongoing and upcoming projects.

Specific qualifications: Experience in either the field of cybersecurity or quantum computing, willingness to learn more about the other. Experience in the fields of theoretical computer science, computer engineering and programming skills are beneficial.
