Universal Quantum Computation in Globally Driven Rydberg Atom Arrays

30 May 2023  ·  Francesco Cesa, Hannes Pichler ·

We develop a model for quantum computation which only relies on global driving, without the need of local addressing of the qubits. Our scheme is based on dual-species processors, and we present it in the framework on neutral atoms subjected to Rydberg blockade constraints. A circuit is imprinted in the (static) trap positions of the atoms, and the algorithm is executed by a sequence of global, resonant laser pulses; we show that this model for quantum computation is universal and scalable.
