The Department of Microtechnology and Nanoscience focuses on research, innovation and education within the fields of future electronics, photonics, bio- and nanosystems. A close collaboration with Swedish and international partners within academia, industry and society enables scientific excellence and creates an innovative environment. In addition to the 200 researchers and PhD students, MC2 houses a cleanroom for micro- and nanofabrication with the latest equipment.

Information about the research and the project
Superconducting circuits are emerging as one of the most promising platforms for the implementation of a quantum computer - i.e. a device in which quantum information can be encoded, processed and read out, and that is expected to solve certain computational tasks faster than classical computers.

Beyond the traditional approach to information encoding based on two-level systems, the so-called Continuous-Variable (CV) approach is emerging as a promising alternative, due to enhanced scalability that it offers. This approach relies on quantized variables with a continuous spectrum: for instance, the position and momentum of a particle, or the amplitude (q) and phase (p) quadratures of the quantized electromagnetic field. In particular, microwave radiation in superconducting cavities can be used at this purpose. Qubits can be encoded therein by using appropriate codes, i.e. states of the radiation that serve as a logical « 0 » and a logical « 1 » states, respectively.

In this PhD project we will study the performances of specific models of quantum computation, such as the adiabatic model, when Continuous-Variable codes are used for information encoding, in the context of superconducting cavities. We will compare these performances to those of the traditional approach based on two-level systems, and study whether practical advantages such as resilience to noise can be gained in one or in the other approach.

We are seeking for a motivated PhD student to join us in this quest. Strong collaborations and exchanges are expected with the experimental group of Per Delsing and Jonas Bylander as well as with the theory group of Göran Johansson, in the context of the Wallenberg Center for Quantum Technologies at Chalmers

Major responsibilities
Your major responsibilities are to pursue your own doctoral studies. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing, in English. The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 20 per cent of working hours.

Position summary
Full-time temporary employment. The position is limited to a maximum of five years.

To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in a relevant field.

The position requires sound verbal and written communication skills in English. Chalmers offers Swedish courses.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
