Delft: Atomic scale coherent spin dynamics

The Otte Lab currently has openings for a postdoc and a PhD student in our group. Each will be working on research related to coherent spin dynamics and ESR-STM (electron spin resonance scanning tunneling microscopy). See below for details.

Research
STM allows for the study of magnetism on the smallest scale: the scale of individual atoms. In recent years, ESR-STM dramatically expanded possibilities by enabling quantum coherent spin manipulation in such atoms. Building further on this framework, our group developed unique methodology to trace the free time evolution of coupled spins using a combination of ESR-STM and very fast DC pulses. This methodology forms the basis for future research on the coherent quantum dynamics of extended spin systems, such as 2D lattices and atomic scale quantum information devices. We are currently also expanding our activities in the direction of hyperfine interactions (i.e. nuclear spin manipulation and readout) and non-contact atomic force microscopy (AFM).

Job description / requirements

PhD student
You will work on a dedicated research project expanding on our latest results. The exact project can be discussed and might evolve as the rapidly expanding field develops. As such, you will be given a lot of freedom in shaping your PhD thesis.

We are looking for an enthusiastic candidate with an MSc degree in physics or a closely related field. Knowledge of quantum mechanics and solid state physics is highly valued. General experience with experimental physics is preferred, but prior experience with specific techniques such as STM is not required.

The contract will be for 4 years with an official go/no go assessment after the first year. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. The application will remain open until a suitable candidate has been found.

Postdoc
As a postdoc you will fulfill an overarching role in the research of our group. In addition to running your own research, you will guide one or more PhD students with their projects. You will also be involved in identifying and developing strategies for future research directions.

The ideal candidate has research experience in a field related to ESR and/or quantum information. Experience with low-temperature STM is desired but not mandatory. The initial contract will be for 2 years. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities. The application will remain open until a suitable candidate has been found.

About our group
We are a focused research group operating two low temperature (1K or below) STM systems equipped with superconducting magnets. We recently upgraded both systems to be compatible with GHz-range radio frequency (RF) signals, bringing them to a state-of-the-art level. In addition, we have acquired high-end RF equipment including a sub-nanosecond arbitrary waveform generator.

The Otte Lab is part of the department of Quantum Nanoscience in the Kavli Institute of Nanoscience at Delft University of Technology. Delft is a lively university town close to larger cities as The Hague and Rotterdam (both ~15 minutes by train) and with Amsterdam within about an hour train distance.

How to apply
In order to apply, please send your CV along with a motivation letter to a.f.otte@tudelft.nl.

Leiden: Chip-based platform for exploring the interface between quantum mechanics and general relativity

The Hensen Lab (a young lab in the Quantum Matter & Optics department of LION in Leiden) is looking for a postdoc to work on "Chip-based platform for exploring the interface between quantum mechanics and general relativity". The project is funded by a European Research Council (ERC) Starting Grant. The project addresses one of the key challenges of modern physics: understanding the interface between quantum mechanics and general relativity. Recently, an experimental test was proposed that can directly witness the need to unify the two theories: observing quantum entanglement between objects that only interact through the gravitational field. A successful test would prove the existence of superpositions of space-time and have far-reaching implications on how we understand our world.

This project aims to develop and characterise an experimental platform that is compatible with the requirements for such a ‘entanglement through gravity’ experiment. The objectives of the research are to trap and levitate a picogram mass, cool its centre-of-mass motion to the quantum ground state, couple its motion to a controllable qubit system and, finally, produce and measure a spatial superposition of the mass.

Delft: Quantum computers and sensors based on diamond and silicon photonics

There are several Postdoc positions available for the topics of quantum-computer and sensor platform technologies using diamond and silicon photonics.

Color centers in diamond exhibit long spin coherence time and capability of optical spin readout. The project will apply nanophotonic structures to the diamond color centers and integrate photonic and CMOS circuits for realization of highly sensitive multimodal sensing devices and highly scalable quantum computer technology platform. The successful candidates will perform new experimental techniques (micro/nanofabrication, quantum optics, cryogenics, electronics,…)

You are required to have a PhD in physics, applied physics or electrical engineering having a strong knowledge on quantum mechanics at the time of taking on the Postdoc position.

The candidates are encouraged to contact Ryoichi Ishihara for further information about the available projects.
