中性原子量子计算博士生

100%, Zurich, fixed-term print The newly established Atom Quantum Processing (AQP) group , led by Prof. Konrad Viebahn, at the Institute for Quantum Electronics within the Physics Department (D-PHYS), ETH Zurich, is seeking a highly motivated Doctoral Candidate. Our research focusses on ultracold neutral atoms and their application in quantum technologies, in particular, quantum computing. We are currently establishing a new laboratory for laser cooling, trapping, and imaging ultracold rubidium atoms in optical lattices. With newly developed methods, such as high-fidelity collisional atom-atom interactions, we build highly coherent quantum machines capable of creating massively entangled quantum states for computing, simulation, sensing, and metrology. Project background Neutral atoms are one of the most promising quantum architectures of today. Yet, the current roadmaps towards neutral-atom fault-tolerant quantum computers are almost exclusively based on Rydberg interactions in optical tweezers. While Rydberg-based gates are fast, they have a massive drawback: finite Rydberg lifetimes and unavoidable decoherence due to spontaneous emission. Instead, our research will employ collisional interactions between atomic qubits, which are highly coherent, passively stable, and very scalable. By using optical lattices instead of optical tweezers we can trap and control more qubits per given laser power, eventually leading to a scalability advantage over the neutral-atom state-of-the-art. We have recently overcome an important bottleneck in optical-lattice-based quantum processors, by integrating topological pumping as a method to shuttle atoms between lattice sites (see publications ). When combined with stable collisional gates, a new quantum architecture emerges with the ability to create massively entangled states, large-scale quantum simulation, quantum sensing and, eventually, fault-tolerant computing. In this experimental Doctoral project, you will play a central role in setting up the experimental apparatus, building a closely-knit team, and developing new concepts in collisional quantum processing.
