PhD

Quantum state tomography and quantum process tomography provide a mathematical groundwork to deduce quantum states and characterize quantum processes from measured data. However, quantum state and process tomography require an exponential number of measurements to reconstruct density or process matrix of a 2^n -dimensional system of n qubits. In this research program, we plan to investigate different approaches to develop scalable quantum tomography techniques.

Photons are excellent candidates to encode and transfer quantum information, however, lack of interaction between photons makes entangling operations and therefore nontrivial quantum states difficult to achieve. Mapping photons onto stationary atomic or solid-state systems can be used to mediate interaction between photons. In this research program we plan to use features of Rydberg physics such as the Rydberg blockade effect to induce non-linearity between photons.

Fully funded PhD positions are available for EU citizens in the cold atoms groups at the University of Nottingham, UK.

Are you a talented and ambitious researcher? Are you excited about quantum science and technology? Do you enjoy finding working solutions to great challenges? You are then welcome to apply for an open PhD position on "Multi-Qubit Quantum Photonic Devices" in our group at DTU Fotonik.

Applications due 21 April.

Skolkovo Institute of Science and Technology (Skoltech) is a unique English-speaking international graduate only research university, located just outside of Moscow. Established in collaboration with M.I.T., Skoltech hosts internationally leading research activities on quantum science and technology, in particular the theory of quantum computers, condensed matter and quantum enhanced algorithms.

A fully funded PhD position for EU citizens is offered for a project on “SpeedDemon: Quantum speed limits in thermodynamic processes and coherent control” in the School of Physics, Trinity College Dublin. The work will be supervised by Dr. Steve Campbell (quantumwizard.weebly.com) through a Starting Investigator Research Grant from Science Foundation Ireland. The project aim to design practical schemes to achieve the ultimate control of complex quantum systems.

Project Description

The PhD project will be in the broad field of non-equilibrium quantum and classical many-body system, including cold atomic gases, quantum optical systems, glassy and driven systems, neural networks and machine learning, and systems at the interface of classical and quantum.

Areas of interest will be the study of the emergence of correlated dynamical states, phase transitions and collective phenomena, and the competition between classical and quantum effects, together with issues of thermalisation and non-ergodicity.

Applications are invited for a Ph.D. position at the Centre for Quantum Computer Science, University of Latvia, lead by prof. Andris Ambainis. The Centre is among the strongest European research groups in quantum algorithms and currently consists of 4 faculty members and 13 postdocs and graduate students.
