Qubits are the basic building blocks of information processing in quantum technology. An Important Research Question is What Material They Will Actually Consist of in Technical Applications. Molecular spin qubits are considering promising qubit candidates for molecular spintronics, in particular for quantum sensing. The Materials Studied here can be stimulated by light; This creates a second spin center and, subsequently, a light-induced quartet state.
UNTIL NOW, Research has assumed that interaction between two spin centers can only be strong enough for successful quartet formation if the centers are covalently linked. Due to the high effort required to synthesise covalently Bonded Networks of Such Systems, Their Use In Application-Related Developments in the Field of Quantum Technology is Severely Limited.
Researchers at the Institute of Physical Chemistry at the University of Freiburg and the Institut Charles Sadron at the University of Strasbourg Have Now Been Able to Show for the First Time that non-Covalent Bonds can allow for Efficient Spin Communication (Nature Chemistry, "Supramolecular Dyads as Photogenérad Candidates").
To do this, the scientists used a model system consisting of a perylenediimide chromophore and a nitroxide radical that self-absemble into functional units in solution by mes of hydrogen leaps. The Key Advantage: The Formation of An Ordered Network of Spin Qubits Could Now Be Achieved Using Supramolecular Approaches, Which Ald Enable The Testing of New Molecule Combinations and System Scalabibility without Major Synthetic effort.
