Summary
The rapidly burgeoning field of Quantum Information Science has boosted the efforts to develop materials capable of exploiting the counterintuitive quantum behaviour of matter. Now at the Second Quantum Revolution, the main stumbling block on the route to quantum computers is the lack of quantum materials with ideal properties. Among the wide variety of systems capable to implement qubits in their electron or nuclear spin, carbon-based molecular qubits (MQBs) bring about advantages such as long coherence times, high reproducibility and scalability. However, crucial deficiencies still need to be solved: the lack of single-qubit readout capabilities and the lack of structure-qubit performance relations to exploit the conscious synthesis of MQBs. In this regard, the recent availability of a broad range of stable designs of organic molecules bearing two unpaired electron spins in their ground electronic state, i.e., diradicals, lead an uncharted market for quantum materials. The main selling point of using diradicals as MQBs resides in the possibility of controlling the interaction between the unpaired spins via chemical synthesis.
In SPECTROBITS, I will investigate new organic diradicals as MQBs to fill the gap in quantum materials. For this, I will establish a direct relation between the spin-spin interaction in diradicals and their performance as MQBs by developing their initialization, readout and manipulation processes. To this end, I will combine my expertise in (time resolved) spectroscopy of diradicals with the expertise of the host in Electron Spin Resonance and Optically Detected Magnetic Resonance, and with advanced quantum chemistry calculations. SPECTROBITS goes beyond the state of the art by investigating the optical addressability of diradical MQBs spanning the whole range of possible spin-spin interactions and by developing single-molecule readout procedures. The final goal is to use these findings to synthetise tailored diradical MQB architectures.
