Extremely accurate measurements of atom states for quantum computing
A new method allows the quantum state of atomic "qubits"—the basic unit of information in quantum computers—to be measured with twenty times less error than was previously possible, without losing any atoms. Accurately measuring qubit states, which are analogous to the one or zero states of bits in traditional computing, is a vital step in the development of quantum computers. A paper describing the method by researchers at Penn State appears March 25, 2019 in the journal Nature Physics.

Stern–Gerlach detection of neutral-atom qubits in a state-dependent optical lattice
A technique based on the coherent splitting of the atoms’ wavefunctions according to their internal states in an optical lattice allows the measurement of neutral-atom qubits in a three-dimensional array with extremely high fidelity, up to 99.94%.
