Quantum gate error reduction – materials and circuit architectures for
superconducting quantum computers, a collaboration between Chalmers
University, Sweden and Aalto University, Finland. 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
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. You will work on reducing the
gate errors that are limited by systematic control errors.
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.
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 (firstname.lastname@example.org)
PI in Finland: Sorin Paraoanu, Aalto (email@example.com)
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
To qualify for the position of postdoc, you must hold a PhD in Physics,
Applied Physics, Nanotechnology, or equivalent. You have experience in
experimental quantum computing, microwave quantum optics, or related fields in
experimental physics. 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.
This postdoc position is a full-time temporary employment for two years.
We offer Chalmers offers a cultivating and inspiring working environment in the
coastal city of Gothenburg.
