In 2022 I have started my first independent research project with the aim of establishing a new experimental platform, namely cold levitated mesoscopic diamonds at high vacuum. We will investigate means for efficient cooling of both the external and the internal temperature of the diamond particles using their internal Nitrogen-Vacancy centers.
The underlying long-term vision is to achieve quantum mechanical coupling between individual spin states and the motion of a macroscopic object.
The project is funded by an ESPRIT grant from the FWF and is hosted by the Quantum Interfaces Group of Prof. Tracy Northup at the University of Innsbruck.
Cavity coupled trapped ions are a promising platform to realize long-range quantum networks due to their superior spin-photon coupling efficiencies and entanglement fidelities, and a communication wavelength compatible for high efficient conversion to telecom frequencies.
In 2022 we have realized entanglement between two trapped ion quantum network nodes across the campus of the University of Innsbruck. This achievement was a joint effort between the teams led by Prof. Tracy Northup and Dr. Ben Lanyon.
The realization of quantum networks requires versatile quantum network nodes to distribute entanglement across the network and to store it for further processing.
As an Erwin-Schrödinger fellow at QuTech, TU Delft, together with a team led by Prof. Ronald Hanson, we have build the first quantum network exceeding two quantum network nodes – a crucial step to realize a future Quantum Internet.
Quantum Simulations are key for the investigation of quantum mechanical properties. By using a well controlled quantum mechanical system one can implement and study tailored Hamiltonians and unlock new types of matter.
During my PhD thesis work in the group of Prof. Francesca Ferlaino I used the toolbox of lattice-confined dipolar atoms to perform Quantum Simulations of exotic inter-atom interactions that extend across neighboring lattice sites.
