If you have a question about this talk, please contact Dr Dimitri M Gangardt. We present a parallelized C-NOT gate which allows to entangle a mesoscopic ensemble of atoms with a single control atom with high fidelity and on a microsecond time scale. Opposed to realization based on a successive application of two-qubit gates the presented scheme works in a single step, requiring solely three laser pulses. The scheme relies on the strong and long-range interaction between Rydberg atoms triggering electromagnetically induced transparency of the ensemble atoms. This many-particle Rydberg gate in combination with optical pumping can constitute the basic building block for efficient digital coherent and dissipative quantum simulation of Hamiltonians with few-body spin interactions. The achieved interaction strength is of the order of 100 kHz. As an example, we discuss the Kitaev’s toric code model on a two-dimensional square lattice.
