Project description
In this project you will join the qLab team at DTU Fotonik in doing research for the development of a semiconductor-based Quantum Network, which is expected to be the energy-efficient and 100%-secure basis of the future Internet. A number of milestones need to be achieved to reach our goal, from entanglement between single-photons and single-spin, to the development of quantum gates.
We plan to do all this using the new and promising Nanowire Quantum Dots.
Nanowire Quantum Dots are semiconductor nano-structures that can be engineered to build quantum-devices such as single-photon emitters, quantum-gates and quantum-registers. Such devices are a few of the key building blocks of a quantum communication system, so many different structures have to be studied, modelled, fabricated and tested.
In our group, we cover the full cycle of activities necessary to simulate, fabricate (cleanroom) and test (quantum optics lab) novel structures and devices, giving to each student the chance to fit wherever he likes the most, to gain the experience he wants or to contribute with his/her best skills to a greater goal. We can offer dedicated projects spanning from purely experimental to theoretical and modelling. Whether you feel like having some hand-on experience in a state-of-the-art cryogenics and quantum optics lab or you prefer modelling of new and untested semiconductor structures, we might have just what you are looking for.
In this project you will learn:
- the basis of single-photons generation from semiconductor structure (learning by deep-diving into books or with hand-on experience!)
- (experimental) how to perform quantum-optics experiments, analyze and comprehend data
- (theory/modelling) how to model novel structures to make efficient semiconductor single-photon sources or quantum devices (e.g. quantum gates)
- how semiconductor-based quantum technologies can be applied in real-world applications
a) Artistic drawing of Nanowire quantum dots (NWQD) interfaced with neutral atoms. b) Simulation of the electronic wavefunction in a NWQD. c) Experimental demonstration of the interface between NWQD and neutral atoms.
