The Quantum Technology Laboratory (QTL) encompasses in general research within the field of quantum technology, focusing on quantum computing, quantum sensing, quantum transduction, quantum thermodynamics and quantum foundations.

The research spans amongst others quantum-processor design and technology, quantum computer software infrastructure, the physics of qubits and superconducting chips, the physics of nanomechanical resonators, exploration of the limits of quantum mechanics, thermodynamical concepts in the quantum regime and microwave-to-optics transduction on the quantum level.

QTL is largely guided by the efforts within the Wallenberg Centre for Quantum Technology (WACQT). A prominent goal of WACQT is to provide a functioning quantum computer with at least a hundred qubits. Such a computer has a far greater computing power than the best supercomputers of today and can be used, for example, to solve optimisation problems or heavy calculations of the properties of molecules. QTL develops such a quantum computer utilizing the experimental platform of superconducting quantum circuits.

QTL comprises five research groups, which are led by Jonas Bylander, Per Delsing, Simone Gasparinetti, Raphaël van Laer, and Witlef Wieczorek.
