Measuring a single atom's position with extreme sub-wavelength resolution and force measurements in the yoctonewton range
P. H. Huber, P. Barthel, Th. Sriarunothai +3
The center-of-mass position of a single trapped atomic ion is measured and tracked in time with high precision. Employing a near-resonant radio frequency field of wavelength 2.37 c…
Robust Two-Qubit Gates Using Pulsed Dynamical Decoupling
Patrick Barthel, Patrick H. Huber, Jorge Casanova +5
We present the experimental implementation of a two-qubit phase gate, using a radio frequency (RF) controlled trapped-ion quantum processor. The RF-driven gate is generated by a pu…
Distinguishing between statistical and systematic errors in quantum process tomography
Sabine Wölk, Theeraphot Sriarunothai, Gouri S. Giri +1
It is generally assumed that every process in quantum physics can be described mathematically by a completely positive map. However, experimentally reconstructed processes are not…
Radio-frequency sideband cooling and sympathetic cooling of trapped ions in a static magnetic field gradient
Theeraphot Sriarunothai, Gouri Shankar Giri, Sabine Wölk +1
We report a detailed investigation on near-ground state cooling of one and two trapped atomic ions. We introduce a simple sideband cooling method for confined atoms and ions, using…
Versatile microwave-driven trapped ion spin system for quantum information processing
Ch. Piltz, Th. Sriarunothai, S. Ivanov +2
Using trapped atomic ions we demonstrate a tailored and versatile effective spin-system suitable for quantum simulations and universal quantum computation. By simply applying micro…
State selective detection of hyperfine qubits
Sabine Wölk, Christian Piltz, Theeraphot Sriarunothai +1
In order to faithfully detect the state of an individual two-state quantum system (qubit) realized using, for example, a trapped ion or atom, state selective scattering of resonanc…
