Biographical details

Dr Arne Grimsmo is pursuing research in quantum mechanics and its applications to technology. His main focus is on quantun technology and information processing using solid state quantum devices.

Research interests

Quantum technology has a wide range of promising applications, from sensing to secure communication and quantum computing. The main challenge for realizing quantum technology is that quantum devices are extremely sensitive to noise. Protecting quantum systems is a subtle balancing act where we simultaneously need to shield the quantum system from its environment and find mechanisms that allows us to manipulate the quantum state. The most sophisticated methods for realizing robust quantum devices today involve a combination of quantum device engineering, quantum error correction and the use of topological properties in quantum systems.

I am particularly interested in quantum electronic devices that offer some built-in protection from noise on the hardware side. In contrast to currently existing quantum technology, classical digital technology makes use of stable states of matter that can retain classical information over long times. Fundamentally this is because stable classical states embody an error correcting code. One of the questions I ask in my research is whether it is possible to realize stable quantum systems that embody quantum error correcting codes.

A second line of my research is about quantum metamaterials built in a bottom-up approach using superconducting quantum circuits. Such metamaterials can have very desirable properties when it comes to both scientific and technologial applications. For example, they can be used to realize ultrasensitive amplifiers, detectors and sensors beating the performance of any analogous classical device. I collaborate with several experimental groups to develop new detectors pushing the boundary on what we can observe in the lab.

Current projects

I'm always looking for motivated PhD students and postdocs who wants to work on quantum information processing and/or quantum optics with solid-state quantum devices. Some of my current research directions include

  • Noise-resilient superconducting quantum circuits
  • Measurement and control of topological superconducting qubits (aka. Majorana qubits)
  • Hardware efficient quantum error correction
  • One-dimensional quantum metatarials and waveguide-QED
  • Numerical simulation tools for open many-body quantum systems
