Design and Implementation of a Blade-Type Linear Paul Trap
Lautaro Ezequiel Filgueira, Marcelo Alejandro Luda, Christian Tomás Schmiegelow
In this work, we present the design, implementation, and construction of a linear Paul trap in a blade configuration. The trap was optimized to minimize micromotion and enable the…
Observation of Space-Dependent Rotational Doppler Shifts with a Single Ion Probe
Nicolás Adrián Nuñez Barreto, Muriel Bonetto, Marcelo Alejandro Luda +2
We present an experiment investigating the rotational Doppler effect using a single trapped ion excited by two copropagating vortex laser beams. The setup isolates the azimuthal gr…
Dark resonance spectra of trapped ions under the influence of micromotion
Nicolás Adrián Nuñez Barreto, Muriel Bonetto, Marcelo Alejandro Luda +2
We study the influence of micromotion on the spectrum of trapped ions with a lambda-type level scheme, leading to dark resonances due to coherent population trapping. We work with…
Compact embedded device for lock-in measurements and experiment active control
Marcelo Alejandro Luda, Martin Drechsler, Christian Tomás Schmiegelow +1
We present a multi-purpose toolkit for digital processing, acquisition and feedback control designed for physics labs. The kit provides in a compact device the functionalities of s…
Scalable creation of long-lived multipartite entanglement
H. Kaufmann, T. Ruster, C. T. Schmiegelow +6
We demonstrate the deterministic generation of multipartite entanglement based on scalable methods. Four qubits are encoded in Ca, stored in a micro-structured segmented…
Entanglement-based dc magnetometry with separated ions
T. Ruster, H. Kaufmann, M. A. Luda +4
We demonstrate sensing of inhomogeneous dc magnetic fields by employing entangled trapped ions, which are shuttled in a segmented Paul trap. As \textit{sensor states}, we use Bell…
Fast ion swapping for quantum information processing
Henning Kaufmann, Thomas Ruster, Christian T. Schmiegelow +6
We demonstrate a SWAP gate between laser-cooled ions in a segmented microtrap via fast physical swapping of the ion positions. This operation is used in conjunction with qubit init…
Manipulating Transverse Modes of Photons for Quantum Cryptography
Marcelo Alejandro Luda, Miguel Antonio Larotonda, Juan Pablo Paz +1
Several schemes have been proposed to extend Quantum Key Distribution protocols aiming at improving their security or at providing new physical substrates for qubit implementation.…
