Experiments in hybrid systems in the Quantum Machines Unit: Magnetic levitation/Optomechanics

The position

The Quantum Machines Unit seeks to develop hybrid quantum devices – where different types of quantum technologies are married together to build devices with unique functionality e.g. quantum sensors, quantum interfaces, probing the fundamentals of quantum mechanics, novel quantum computing architectures etc. Quantum Machines studied within the Unit can incorporate a wide variety of quantum technological platforms including superconducting quantum circuits, quantum optical, neutral atoms, solid-state, and mechanical quantum systems. In addition to theoretical work the Unit is focused on developing experimental quantum technology based on the preparation of quantum states of motion using magnetic levitation of small objects in vacuum. Such levitated nanoparticles may prove useful for the investigation of macroscopic Schrodinger Cats – which are useful for precision sensing and probing the fundamental links between gravity and quantum mechanics.


We are seeking talented researchers to perform experimental research in the field of hybrid quantum machines and in particular in either magnetic levitation or in optomechanics. Research in the topic of magnetic levitation focuses on supporting an object in 3D in vacuum using only magnetic forces. Research in the topic of optomechanics focuses on coupling moving objects to optical fields. We seek experimentalists with expertise in any of the following: optomechanics, magnetic engineering, cavity QED, optical resonators, experimental vacuum, cryogenic, electronics, photonics. Expertise in fast feedback systems e.g. FPGA, PID, etc is also desirable.

  1. Perform experimental research related to the core focus of the Unit – Quantum Machines – developing innovative quantum devices – under the direction of the Head of the Unit, Prof Jason Twamley and the dissemination of these research results via publication of journal articles, participation in national and international conferences, media releases and other output channels.
  2. Contribute towards building an inclusive, dynamic and respectful research ethos within the Quantum Machines Unit including participation in: Unit Seminar Programs, Unit meetings, Unit mentoring of graduate/intern students, Unit Journal Club etc.
  3. Postdoctoral Researchers are encouraged to pursue their own independent research while working at OIST. It is the responsibility of the researcher and the Head of the Unit Prof Twamley, to ensure that any additional projects they take on have no conflict with their responsibilities within the QM group and with others within OIST.


  1. PhD in physics or a related discipline.
  2. Prior experience in research related to experiments related to hybrid quantum systems or to magnetic levitation or optomechanics.
  3. Proficiency in spoken and written English.


  1. Prior experience in numerical methods related to quantum science and technology e.g. Mathematica, python, Matlab etc.
