Strong and Ultrastrong Coupling with QD-Cavity Hybrid Architecture
Project description
A quantum dot (QD) embedded in a circuit quantum electrodynamics (cQED) architecture offers a promising platform for both quantum information processing and the study of fundamental light-matter interactions, as well as enabling analog quantum simulations. Recent experiments have demonstrated strong coupling in semiconducting QD-cavity hybrid devices, where resonator microwave photons interact with the charge [1,3,4] or spin [2,5,6] degrees of freedom in QDs via their electric dipolar interaction.
A particularly compelling direction for future research is achieving ultrastrong coupling [7,8] between superconducting cavity photons and QD electrons, which could be realized by increasing resonator impedance, enhancing electric field fluctuations, and optimizing gate lever arms [8,10].
Our research focuses on double quantum dots (DQDs) defined in planar Germanium [9] and crystal-phase-defined DQDs within InAs nanowires [10,11]. The strong spin-orbit interaction (SOI) in these semiconductor materials simplifies spin qubit design, enabling rapid spin manipulation through electrical signals and eliminating the need for micromagnets.
Building on these properties, strong coupling between microwave photons and charge qubits in planar Ge [9], as well as charge [10] and singlet-triplet qubits [11] in InAs nanowires, has recently been demonstrated. These advancements pave the way for significant progress in quantum technologies, making this an exciting and impactful field of research.
Profile
We are seeking highly motivated candidates with a strong interest in quantum technology involving semiconducting and/or superconducting quantum circuits. Proficiency in English (reading, writing, and scientific discussion) is essential, along with excellent teamwork and communication skills.
PhD in physics, quantum engineering, or electrical engineering, ideally with a focus on semiconducting/superconducting devices.
Extensive experience in nanofabrication, cryogenics, microwave design, and microwave measurements. Expertise in fabricating electrically defined QDs and nanowire-based quantum devices is a plus.
Strong research skills with a demonstrated ability to conduct independent research.
Proven ability to collaborate effectively within a team.
Demonstrated initiative, results-oriented mindset, strong organizational skills, and creativity.

PhD position at IBM Research Zürich - Topological materials at the nanoscale
Project description
We are seeking an enthusiastic PhD candidate to join our topological materials team at IBM Research – Zurich. The candidate will enroll in the PhD programme of ETH, Switzerland, while doing their PhD work at IBM.
Topological conductors include many different materials with exotic transport properties, such as Weyl and Dirac semimetals.
