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…
Speeding-up the decision making of a learning agent using an ion trap quantum processor
Theeraphot Sriarunothai, Sabine Wölk, Gouri Shankar Giri +4
We report a proof-of-principle experimental demonstration of the quantum speed-up for learning agents utilizing a small-scale quantum information processor based on radiofrequency-…
Analog Quantum Simulation of (1+1)D Lattice QED with Trapped Ions
Dayou Yang, Gouri Shankar Giri, Michael Johanning +3
The prospect of quantum simulating lattice gauge theories opens exciting possibilities for understanding fundamental forms of matter. Here, we show that trapped ions represent a pr…
Experimental system design for the integration of trapped-ion and superconducting qubit systems
D. De Motte, A. R. Grounds, M. Rehák +8
We present a design for the experimental integration of ion trapping and superconducting qubit systems as a step towards the realization of a quantum hybrid system. The scheme addr…
Measurement of the half-life of the T= mirror decay of Ne and its implication on physics beyond the standard model
L. J. Broussard, H. O. Back, M. S. Boswell +19
The superallowed mixed mirror decay of Ne to F is excellently suited for high precision studies of the weak interaction. How…
Isotope Shifts of the D - P Transition in Trapped Short-Lived Ra
G. S. Giri, O. O. Versolato, J. E. van den Berg +13
Laser spectroscopy of short-lived radium isotopes in a linear Paul trap has been performed. The isotope shifts of the D - P transition in $^{209…
On-line Excited-State Laser Spectroscopy of Trapped Short-Lived Ra Ions
O. O. Versolato, G. S. Giri, L. W. Wansbeek +11
As an important step towards an atomic parity violation experiment in one single trapped Ra ion, laser spectroscopy experiments were performed with on-line produced short-lived…
Production of short lived radioactive beams of radium
P. D. Shidling, G. S. Giri, D. J. van der Hoek +7
Short lived Ra isotopes have been produced at the TRIP facility in inverse kinematics via the fusion-evaporation reaction Pb+C at 8 MeV/u. Isotope…
