Time-adaptive phase estimation
Brennan de Neeve, Andrey V. Lebedev, Vlad Negnevitsky +1
Phase estimation is known to be a robust method for single-qubit gate calibration in quantum computers, while Bayesian estimation is widely used in devising optimal methods for lea…

Low-excitation transport and separation of high-mass-ratio mixed-species ion chains
Francesco Lancellotti, Stephan Welte, Matteo Simoni +6
We demonstrate low-excitation transport and separation of two-ion crystals consisting of one beryllium and one calcium ion, with a high mass ratio of . The full separation inv…

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…
