- Adaptive optics for precision control of optical qubits
We are looking for a highly motivated Masters student who would help us to bring our spatial light modulator systems to the next level. We have an unusual application that requires top-notch control over both intensity and phase of individual optical tweezers used to drive the strontium optical qubit. We have done promising initial work for low numerical aperture and are looking for someone to extend our techniques to high-resolution microscope objectives. Working on this novel optical addressing system will teach you about state-of-the-art optical microscopy, coherent and white-light interferometry, as well as ultrastable lasers. This Masters project is open-ended in that depending on how far you get, you will build your adaptive optics setup into our experiment and start performing precision laser spectroscopy on the strontium optical qubit with high spatial resolution. You will join an international team of highly-motivated researchers from the Bachelor to the Postdoc level. This 12-month experimental Masters project will give you a full overview over the skills required to succeed in any experimental atomic physics laboratory worldwide. Please have a look at the previous Masters theses on our website (https://ultracold.sr/) to get a feeling for the breadth and depth of knowledge that you will develop.

- FermiQP: Lithium MOT and Optical Transport
-
We are starting a new project on building a next generation Fermion Quantum Processor, FermiQP. The project aims at realizing a scalable hybrid platform for analogue quantum simulation and digital quantum computing. The new architecture will create advantages that no other platform can offer, first and foremost the possibility of using a quantum machine in two fundamentally different operating modes: An analogue mode, in which a quantum advantage is expected in the short term for specific questions in the field of quantum materials, as well as a digital mode, in which the processor is universally programmable.
The new machine will operate on ultracold fermionic lithium atoms in optical lattices and build on the recent successes in single atom resolved manipulation and readout in quantum gas microscopes. More information about FermiQP is available at
https://www.mpq.mpg.de/6547261/fermiqp
The backbone of the FermiQP architecture is a machine to produce clouds of ultracold atoms at high repetition rates. Within this project, a student will design and build the core of a new setup for ultracold lithium. First, the student will set up and characterize a magneto-optical trap (MOT). Second, the student will implement an optical transport system that can move a cold cloud of atoms between different sections of the vacuum chamber. The student will learn how to work with ultrahigh vacuum systems, magnetic field coils and high-power lasers.

Within FermiQP, quantum information will be encoded in the hyperfine spin states of lithium atoms. To guarantee long coherence times, extremely stable magnetic fields of up to 700 G will be needed. At the same time, high Rabi rates in the radio frequency and microwave domain are required to achieve high-fidelity single-qubit rotation. This project will develop the sensors, feedback and control electronics to realize stable magnetic fields at the ppm level as well as radio frequency and microwave systems to drive single-qubit rotations. The student will learn how to design, build, and characterize high-power DC and RF electronics and incorporate their setup in a quantum gas machine at the forefront of quantum science.

- High-flux atomic source for quantum simulators and optical lattice clocks
-
We are looking for a highly motivated Masters student who would would
work on a next-generation strontium atomic beam source. This source will
allow us to reduce the cycle time of our quantum simulation and atomic
clock experiments, to dramatically improve the signal-to-noise of all of
our experimental results. Working on this next-generation source will
teach you about precision mechanical design, ultrahigh vacuum
technology, how to build and stabilize diode lasers, and you will do
hands-on work on laser cooling and spectroscopy of atomic beams. This
Masters project is open-ended in that depending on how far you get, you
will integrate your source into our experiment and go on from there. You
will join an international team of highly-motivated researchers from the
Bachelor to the Postdoc level. This 12-month experimental Masters
project will give you a full overview over the skills required to
succeed in any experimental atomic physics laboratory worldwide. Please
have a look at the previous Masters theses on our website
(https://ultracold.sr/) to get a feeling for the breadth and depth of
knowledge that you will develop. For this project, especially check out
the Masters theses of Etienne Staub and Eva Casotti.

- Laser systems for quantum computing with Rydberg atoms
- Arrays of single atoms trapped in optical microtraps are among the promising platforms to realize analog and digital quantum computers and quantum simulators. Manipulation, trapping and detection of the qubits requires special-purpose laser systems at various wavelengths reaching from the ultraviolet into the infrared spectral range. Within your project, you will design, construct and benchmark such a laser system with the goal to implement it in our neutral-atom quantum computing platform. You will acquire deep knowledge on the technological and physical basis of neutral-atom quantum processors. Specifically, you will learn about cw laser technology, laser-frequency stabilization, optics, optomechanics, fast feedback electronics, as well as atomic physics. You should bring the motivation and drive to tackle challenging problems and come up with creative technical and physical solutions. In return, you will enjoy being part of a highly motivated team in a dynamically evolving field of research at the intersection between atomic physics, condensed matter physics and quantum information.

- Quantum Gas Assembler: Dynamically tunable optical traps
- Ultracold quantum gases in optical lattices are complex quantum systems with strong similarities to many iconic condensed matter models. At the same time, they can be imaged and manipulated on the single-particle level, providing an exceptional arena for the experimental study of new phenomena in quantum many-body physics. Traditionally, quantum gases are prepared by evaporation of thousands of atoms that are slowly loaded into optical lattices. This approach provides the lowest temperatures to date, but it is also limited to certain types of states, and most importantly, it is only compatible with long cycle times and low data rates. We are starting a new project based on ultracold lithium that will assemble quantum gases from individually cooled atoms, such that arbitrary initial states can be prepared at much higher data rates. This will open the door to new statistical analyses and correlation measures. In this project, a Masters student will design and construct the optical system for dynamically tunable dipole traps. The project entails setting up high-power lasers and tunable lens system to realize a versatile trap setup at the heart of the new apparatus. The project will be carried out in close collaboration with the PhD students on the project and the PI (Philipp Preiss).

Starting from a 2D MOT, the student will develop the magnetic field setup, control electronics and optical potentials needed to create degenerate clouds of lithium atoms. This will provide insights into all aspects of a quantum gas experiment, including laser systems, optics, and electronics.

- Ultra-low noise diode lasers for optical lattice quantum simulators
- We are looking for a highly motivated Masters student who would would help us to develop diode laser sources in the visible that can trap atoms at detunings of several GHz from a kHz-wide optical transition. This is a very special use case that requires deep thought on how to reduce the intensity and phase noise of the lasers in a regime that's relatively unexplored. Working on this novel laser system will teach you about optical cavities and how to build, stabilize, and characterize your own diode lasers. This Masters project is open-ended in that depending on how far you get, you will integrate your laser system into our experiment and trap strontium atoms in optical lattices created by your lasers, and go on from there.
