Quantum computation schematic

(1) Qubits are prepared or read-out individually, in spatially different zones. (2) Two qubits are brought together in order to perform a two-qubit operation. (3,4) Qubits can be transported to and from other trap segments, allowing for the experimental realization of complex quantum algorithms involving several interacting qubits. Credit: NIST.
