• Abstract: Quantum simulation aims to recreate complex many-body phenomena in controlled environments, offering insights into dynamics that are otherwise difficult to model. Existing platforms, however, are often complex and costly to scale, typically requiring ultra-pure vacuum or low temperatures. Here, we realize a room-temperature quantum simulator using a thin ${}^{13}\text{C}$ nuclear spin layer in diamond. Nearby nitrogen-vacancy centers enable polarization, readout, and, combined with radio-frequency fields, coherent control of the nuclear spins. We demonstrate strong, tunable interactions among the nuclear spins and use the system to investigate discrete time-crystalline order. By combining ease of use with operation at ambient temperatures, our work opens new opportunities for investigating strongly correlated many-body effects.

  Nuclear spins in certain solids couple weakly to their environment, making them attractive candidates for quantum information processing and inertial sensing. We demonstrate optical nuclear spin polarization and rapid quantum control of nuclear spins in a diamond physically rotating at $1,$kHz, faster than the nuclear spin coherence time. Our work liberates a previously inaccessible degree of freedom of the NV nuclear spin, unlocking new approaches to quantum control and rotation sensing.

The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.

  Localized electronic and nuclear spin qubits in the solid state constitute a promising platform for storage and manipulation of quantum information. We propose and analyze a scheme that employs a parity measurement in a decoherence free subspace to enable fast and robust entanglement generation. We find that high-fidelity entanglement at cryogenic and even ambient temperatures is feasible with realistic parameters, and show that the entangled pair can be subsequently leveraged for deterministic controlled-NOT operations.
