The Quantum Device Lab
provides a state-of-the-art research environment at the Department of Physics of ETH Zurich to study the quantum properties of novel micro- and nano-structured electronic devices and their interaction with classical and quantum electromagnetic fields. In a promising hybrid approach we combine semiconductor quantum dots (QD) with superconducting microwave cavities to achieve strong coherent coupling between the electric dipole moment of electrons confined in quantum dots and microwave photons stored in on-chip cavities . This approach opens new possibilities to explore the physics of semiconductor quantum dots using sensitive and large bandwidth measurement schemes initially developed in the context of superconducting circuits.
Within the Swiss National Science Foundation (SNSF)-funded project ‘Elements for Quantum Information Processing with Semiconductor/Superconductor Hybrids (EQUIPS)’ we search to employ a talented, skilled and highly motivated
Doctoral Student or Postdoctoral Researcher (100%) in Quantum Hybrid Systems
The research position
aims at exploring concepts of semiconductor circuit QED with GaAs based double QD (DQD) charge qubits strongly coupled to high impedance microwave resonators made from Josephson junction arrays or high kinetic inductance thin films. Furthermore, we plan to transition to Si based QDs with natural or induced spin-orbit coupling to employ the more coherent spin degree of freedom of electrons in DQDs. Circuit QED in the strong coupling regime will allow quantum non-demolition (QND) read-out of qubits, remote coupling between qubits, and communication between on-chip quantum device elements.
The work will be done in close collaboration with the Nanophysics Group at the Department of Physics of ETH Zurich. The position is available immediately. Applications will be accepted until the position is filled.
Candidates are required to have a Master/PhD with a focus on quantum physics and, ideally, a solid background in quantum information processing with superconducting circuits and/or semiconductor qubits. The successful candidate is curious to learn new experimental techniques and is eager to expand their current expertise in microwave engineering, signal processing, nano- and micro-fabrication, low-temperature and semiconductor physics, control and measurement automation or data analysis (Mathematica, Matlab, Python, etc…).
