Come to the cutting edge of quantum technology - join our multi-talented, collaborative team working toward the common goal of building a 100-qubit quantum computer by 2025. You will be part of the most exciting things happening in this field, such as the Wallenberg Centre for Quantum Technology (WACQT) in Sweden, the Centre of Excellence Quantum Technology Finland (QTF), and the EU Flagship on Quantum Technology OpenSuperQplus.
Information about the project
The reduction of quantum gate errors represents the most important problem in the development of quantum computers in any technological platform. By this metric, superconducting qubits constitute a leading platform, with the best demonstrated two-qubit gate errors currently at the 0.1-0.2% level. Meaningful quantum computing requires that these errors be reduced to 0.01% in a scalable and reliable way across the multi-qubit chip. To achieve this, we will deploy advanced theoretical methods and we will implement the protocols experimentally. Progress in this direction will constitute a major breakthrough in quantum computing, as it will open the way to realistic implementations of error correction.
As a postdoc working on this collaborative project you are expected to spend 50-75% of your time at Chalmers, with substantial research visits to Aalto. You will have the unique opportunity of experiencing the working culture in top-level research groups in two Nordic countries.
The project is funded for 2 years by WACQT with the possibility of a 5-month ramp-up phase in 2022 funded by QTF. The Project has two PIs:
PI in Sweden: Giovanna Tancredi, Chalmers (
tancredi@chalmers.se)
PI in Finland: Sorin Paraoanu, Aalto (
sorin.paraoanu@aalto.fi)
Major responsibilities
In a superconducting quantum processor, quantum gates are realized by on-resonant or near-resonant microwave pulses with the intent of inducing Rabi oscillations on the desired qubit. However, standard Rabi pulses are not robust against errors in frequency and timing, and they are also not optimal with respect to leakage into higher excited qubit states. The goal of this project is to use advanced methods in optimal control theory to accurately manipulate control pulses for generating both single and two-qubit gates. You are expected to develop these optimal control techniques and to experimentally demonstrate improvement of the quantum gate fidelities of Chalmers quantum processors. You will work on reducing the gate errors that are limited by systematic control errors.
Qualifications
To qualify for the position of postdoc, you must hold a PhD in Physics, Applied Physics, Nanotechnology, or equivalent. Experience in experimental quantum computing, microwave quantum optics, or related fields in experimental physics will be highly appreciated, but we are looking also for theorists who would engage closely to our experimental groups. You are motivated for a career in quantum technology, be it in academia or at an institute or company. You have a collaborative attitude and an interest in working both independently and collaboratively in a team environment, sharing best practices and assuming responsibility. You pay attention to detail and enjoy to solve complex problems. You are also willing to help supervise PhD students. The position requires sound verbal and written communication skills in English.
Contract terms
This postdoc position is a full-time temporary employment for two years.
