Ph.D./Postdoc Position
Multimode quantum electrodynamics
Hybrid Quantum Circuit Laboratory, EPFL

The Hybrid Quantum Circuit laboratory (HQC) in EPFL is looking for an outstanding candidate for a PhD/Postdoctoral position in the field of experimental multimode quantum electrodynamics to study many-body interactions in extreme coupling regimes and qubits coupled to a chiral topological waveguide.

The aim of this project is to develop analog quantum simulation platforms to emulate quantum impurity models in the ultra-strong coupling regime and complex spin systems using atom-photon bound states.

Ph.D. Position
Diamond nanostructures for UV photonics
Laboratory of Quantum and Nano-Optics, EPFL

A fully funded PhD candidate position is available in the Laboratory for Quantum and Nano-Optics (EPFL) with joint supervision by Prof. Niels Quack from the Photonic Micro- and Nanosystems Laboratory at the University of Sydney (Australia), and in collaboration with the University of Ghent (Belgium).

The goal of the project is to fabricate single-mode diamond waveguides and photonic integrated circuits for performing resonant Raman spectroscopy in the UV domain, with applications in molecular sensing.

Bachelor/Semester/Master Project
Quantum Optics and FPGAs
Quantum Optics Lab, ETH Zurich

The Quantum Optics Laboratory at ETH Zurich is looking for a student to work on a project titled “FPGA-based dual-camera readout for fast laser beam profiling”. Stable and well-defined laser beams are a base requirement for quantum experiments based on ultra-cold atoms in order to precisely control the physics. The current implementation doesn’t perform any real-time interaction with a laser control electronics or the experiment. Therefore, it requires further improvements to make the system ready to use in quantum experiments and testing in the lab.

Master Thesis Position
Quantum Optomechanics
IBM Research, Zurich

We are seeking highly motived candidates for master’s theses on experimental cavity quantum optomechanics in the Quantum Technology group at IBM Research. In optomechanics, radiation pressure is used to create a coherent coupling between an optical cavity and a mechanical resonator. This highly active field of research has led to several breakthrough experiments like ground-state cooling of massive mechanical oscillators using light, quantum-limited measurement of mechanical motion, as well as entanglement between single photons and phonons.

Ph.D. Position
Strongly correlated quantum matter group
Innsbruck University

The Strongly correlated quantum matter group, Innsbruck University is looking for motivated PhD students to work on quantum simulation on a novel cavity QED platform in construction for the interfacing of Yb atoms with a high-Finesse cavity. The atoms will be positioned with sub wavelength resolution inside the cavity mode using tweezer traps.

Master Thesis Position
Realizing a quantum communication protocol between distant superconducting circuits
Quantum Device Lab, ETHZ

A promising way of scaling up quantum computers based on superconducting circuits is to connect individual quantum processors with each other, in the form of a quantum LAN. In the Quantum Device Laboratory at ETHZ we have built a 30 meter long cryogenic connection between such quantum processors – a setup which is unique in the world. This system allows for the entanglement of distant superconducting qubits, and for establishing quantum communication between them. And that’s where you come into play:

We are looking for a motivated master student who helps us implement such quantum communication protocols. You will get a hands-on experience on the setup, learn the various aspects of it that must come together for the implementation of this experiment, with a focus on chip design & characterization, microwave engineering, and software.Feel free to contact us to get to know us and your potential project in greater detail.

Master Thesis Position
Towards building a novel ion-trap array for quantum simulation in the NISQ regime
TIQI Group, ETHZ

The Noisy Intermediate-Scale Quantum (NISQ) era is the next frontier of quantum simulation and quantum computing, comprising devices on the order of ~100 qubits, with capabilities beyond the best of today’s classical computers. Trapped-ion chains in radio-frequency traps have realised some of the highest qubit coherence times and quantum gate fidelities, but are typically limited to ~10 qubits due to technical limitations arising from the radio-frequency micromotion. These limitations make it hard to scale up the system into two-dimensional arrangements of ion-based qubits. The IONPEN research project at the TIQI group seeks to address this issue of scalability with the novel approach of cryogenic micro-fabricated planar Penning traps that in principle will be capable of trapping 2-d arrays of hundreds of ion qubits in the absence of micromotion. Currently we are in the process of constructing, characterising and optimising a number of elements of the design of an experimental setup to that end, with the initial goal of trapping ions for the first time. This particular masters project would entail hands-on experimental work on several important aspects that go towards building this novel ion-trap apparatus. These involve working with a cryogenic ultra-high vacuum system within a superconducting magnet, generation and delivery of high-frequency microwave radiation, setup of laser optics and imaging systems, and constructing and testing control electronics.

Duration: FS2021 (Starting dates flexible, but preferably March/April)
