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…
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…
Towards Two Bloch Sphere Representation of Pure Two Qubit States and Unitaries
Stanislav Filatov, Marcis Auzinsh
We extend Bloch Sphere formalism to pure two qubit systems. Combining insights from Geometric Algebra and analysis of entanglement in different conjugate bases we identify Two Bloc…
