Entangling ions with engineered light gradients
Tommaso Faorlin, Lorenz Panzl, Phoebe Grosser +12
Spectral crowding of collective motional modes limits the fidelity of entangling interactions in trapped-ion quantum processors by inducing off-resonant coupling to spectator modes…
Robust certification of non-projective measurements: theory and experiment
Raphael Brinster, Peter Tirler, Shishir Khandelwal +7
Determining the conditions under which positive operator-valued measures (POVMs), the most general class of quantum measurements, outperform projective measurements remains a chall…
Single-ion optical autocorrelator
M. I. Hussain, M. Guevara-Bertsch, E. Torrontegui +3
Well isolated quantum systems are exquisite sensors of electromagnetic fields. In this work, we use a single trapped ion for characterizing chirped ultraviolet (UV) picosecond lase…
Multi-GHz repetition rate, multi-watt average power, ultraviolet laser pulses for fast trapped-ion entanglement operations
M. I. Hussain, D. Heinrich, M. Guevara-Bertsch +4
The conventional approach to perform two-qubit gate operations in trapped ions relies on exciting the ions on motional sidebands with laser light, which is an inherently slow proce…
Ultra-fast two-qubit ion gate using sequences of resonant pulses
E. Torrontegui, D. Heinrich, M. I. Hussain +2
We propose a new protocol to implement ultra-fast two-qubit phase gates with trapped ions using spin-dependent kicks induced by resonant transitions. By only optimizing the allocat…
Trapped-ion antennae for the transmission of quantum information
Maximilian Harlander, Regina Lechner, Michael Brownnutt +2
More than one hundred years ago Heinrich Hertz succeeded in transmitting signals over a few meters to a receiving antenna using an electromagnetic oscillator and thus proving the e…
