Quantum simulator with 40 nuclear spins in diamond — •Christina Ioannou — Qutech, TuDelft, Netherlands
Individually controllable 13C nuclear spins in diamond, associated with a single NV-center, can be used to realise a quantum simulator for the observation of many-body quantum phenomena. On this poster I will discuss the capabilities of the platform such as collective initialisation with dynamic nuclear polarisation, individual spin control and readout as well as global pulses, which make up a comprehensive toolbox for studying many-body phenomena under a range of tunable Floquet Hamiltionians. Applications of this quantum simulator include observing novel phases of matter such as discrete time crystals, studying the thermalisation a many-body 3D-coupled spin system under Floquet driving, Hamiltonian engineering and estimating entanglement entropies with randomised measurements.
