- Abstract: The use of $d$-level qudits instead of two-level qubits can largely increase
the power of quantum logic for many applications, ranging from quantum
simulations to quantum error correction. Molecular Nanomagnets are ideal spin
systems to realize these large-dimensional qudits. Indeed, their Hamiltonian
can be engineered to an unparalleled extent and can yield a spectrum with many
low-energy states. In particular, in the last decade intense theoretical,
experimental and synthesis efforts have been devoted to develop quantum
simulators based on Molecular Nanomagnets. However, this remarkable potential
is practically unexpressed, because no quantum simulation has ever been
experimentally demonstrated with these systems. Here we show the first
prototype quantum simulator based on an ensemble of molecular qudits and a
radiofrequency broadband spectrometer. To demonstrate the operativity of the
device, we have simulated quantum tunneling of the magnetization and the
transverse-field Ising model, representative of two different classes of
problems. These results represent an important step towards the actual use of
molecular spin qudits in quantum technologies.
