Roto-Reflection Geometry of Pure Two-Qubit Entanglement
Stanislav Filatov, Marcis Auzinsh
Pure two-qubit entanglement is usually characterized by scalar quantities such as concurrence. Here we show that it also has a natural geometric form. In the Pauli correlation tens…
Using NV centers in diamond to detect DC to very-low frequency magnetic fields
Valts Krumins, Ivars Krastins, Oskars Rudzitis +3
In this work we present a compact and portable tabletop magnetometer that utilizes negatively charged nitrogen-vacancy (NV) centers in diamond. The magnetometer is operated using a…
Multi-parameter study of two-axis Hanle magnetometry on the Cs D line
Arturs Mozers, Antons Nikolajevs, Florian Gahbauer +1
We have studied experimentally and theoretically the impact of various parameters on the characteristics of signals from a two-axis Hanle magnetometer based on the Cs D transit…
Radio-frequency induced Autler-Townes Effect for single- and double-photon magnetic-dipole transitions in the Cesium ground state
Arturs Mozers, Linda Serzane-Sadovska, Florian Gahbauer +1
We have observed the Autler-Townes effect in single- and suspected double-photon magnetic-dipole transitions in the Cesium ground-state magnetic-sublevel manifold. Experiments were…
Entanglement on Two Bloch Spheres: Exploring Two-Qubit Stabilizer Group Structure
Stanislav Filatov, Marcis Auzinsh
In this paper, we explore the graphical representation of two-qubit entanglement on two Bloch Spheres via stabilizer formalism. We relate the density matrix to the graphical repres…
