Molecular Spins for Quantum Applications



Quantum information technology, one of the pillars of the technological revolution that is foreseen for the next decades, has its core in the quantum bit, or qubit, i.e., a two states quantum−mechanical system able to be placed in a state of coherent superposition of these two states. Physical realizations of qubits can be found in many systems, but recently magnetic molecules have attracted interest thanks to their chemical tunability. The group is focusing on: (i) fundamental mechanisms governing the spin dynamics for a rational design of molecular qubits; (ii) their assembling on surfaces to achieve single molecule addressing; (iii) the synthesis of multi-spin systems to realize quantum gates; (iv) exploitation of chirality-induced spin selectivity to control and readout the spin.
