5X5 Qubit Arrays Sorted And State Detected (IMAGE)
Caption
A new method allows extremely accurate measurement of the quantum state of atomic qubits -- the basic unit of information in quantum computers. Atoms are initially sorted to fill two 5x5 planes (dashed yellow grid marks their initial locations). After the first images are taken, microwaves are used to put the atoms into equal superpositions of two spin states. A shift to the left or right in the final images corresponds to detection in one spin state or the other. Associated square patterns denote atom locations (cyan: initial position, orange and blue: shifted positions).
