Postdocs: Quantum computers

Come to the cutting edge of quantum technology – join our multi-talented, collaborative team working toward the common goal of building a quantum computer. You will be part of the most exciting things happening in this field, such as the EU Flagship on Quantum Technology and the Wallenberg Centre for Quantum Technology.

About us
Our ambitious goals at Chalmers are to build a quantum computer, and to apply it to real computational problems that cannot be efficiently solved on a conventional computer. Such computationally hard problems are found, e.g., in optimization, machine learning, quantum chemistry, materials science, etc. 

These efforts are supported by the Wallenberg Centre for Quantum Technology (WACQT) and the OpenSuperQ project of the EU Flagship on Quantum Technology. Several industrial companies interested in applications of quantum computing are members of WACQT and OpenSuperQ, and they are developing relevant use cases in collaboration with us.

Building a quantum computer requires a multi-disciplinary effort between experimental and theoretical physicists, electrical and microwave engineers, computer scientists, software engineers, and researchers within materials science and nanotechnology. We are developing the superconducting quantum devices and control circuits, materials, firmware, and methods required to make the quantum computer reality. We work in close collaboration between the experimentalists in the Quantum Technology Laboratory (QTL), Quantum Device Physics Laboratory (QDP) and the theorists at the Applied Quantum Physics Laboratory (AQPL). The theorists help model the hardware as well as developing application use cases for the quantum processor. Our team currently has about 50 members – faculty, permanent research staff, post-doctoral researchers, PhD students, and master’s / undergraduate students – and is expanding.

Our department is host to the state-of-the-art MC2 Nanotechnology Laboratory cleanroom, and our measurement lab at QTL is well equipped with cryogenic and microwave electronic equipment. Our qubits are state of the art. We are in a position to build and operate a quantum processor!

We are now seeking to fill POSTDOCTORAL positions with focus on,

• Development of high-performance superconducting quantum circuits
The fidelity of the quantum gate operations is known to be limited by environmental noise and interaction with spurious two-level fluctuators (TLF). Revealing the physical nature of environmental TLF and understanding the fundamental mechanisms leading to decoherence are the two long-standing challenges in engineering the solid-state quantum devices. We aim to understand the physics of decoherence and to find the way to mitigate the sources of decoherence with refined fabrication techniques. Recently we have made significant advances towards this ambitious goal and look for a continuation of this successful research line. This job involves process technology development, fabrication, and device characterization at single-photon probe power.  

• Development of 3D-integrated superconducting quantum processors
Maintaining high quantum-gate fidelities presents a challenge for scalable quantum processor architectures comprising dozens of qubits on a chip. In order to accommodate the input/output circuitry required to address all qubits and couplers, we are developing a multi-layer, integrated device technology. This job involves device/circuit architecture and design, process technology development, fabrication, electronics packaging, and characterization.

About You
We are looking for expertise in nanotechnology and fabrication of thin films and micro/nanoscale electronic devices, electronics packaging, superconductor technology, and characterization techniques. Further desired skills include the design, modeling, and characterization of solid-state devices, electrical modeling and characterization techniques on microwaves and dc, numerical simulations, low-temperature techniques, noise processes, electromagnetism, solid-state and quantum physics, and cryogenic techniques. Knowledge of materials and surfaces is desirable.

• You have a PhD in Physics, Applied Physics, Nanotechnology, or equivalent
• Your verbal and written communication skills in English are very good
• 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 are self-motivated, pay attention to detail, and possess a problem-solving analytical ability. You are willing to help supervise PhD students
• In cases of an exceptionally good fit (experience, level, and motivation), a permanent researcher position could become available.
