Direct characteristic-function tomography of quantum states of the trapped-ion motional oscillator
Christa Flühmann, Jonathan P. Home
We implement direct readout of the symmetric characteristic function of quantum states of the motional oscillation of a trapped calcium ion. Using suitably chosen internal electron…

Encoding a qubit in a trapped-ion mechanical oscillator
Christa Flühmann, Thanh Long Nguyen, Matteo Marinelli +3
The stable operation of quantum computers will rely on error-correction, in which single quantum bits of information are stored redundantly in the Hilbert space of a larger system.…

Repeated multi-qubit readout and feedback with a mixed-species trapped-ion register
Vlad Negnevitsky, Matteo Marinelli, Karan Mehta +3
Quantum error correction will be essential for realizing the full potential of large-scale quantum information processing devices. Fundamental to its experimental realization is th…
