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…
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…
Relating quantum incoherence, entanglement and superluminal signalling
Stanislav Filatov, Marcis Auzinsh
Hereby we inspect two-partite entanglement using thought experiment that relates properties of incoherently mixed states to the impossibility of faster-than-light (FTL) signalling.…
On Interchangeability of Probe-Object Roles in Quantum-Quantum Interaction-Free Measurement
Stanislav Filatov, Marcis Auzinsh
In this paper we examine Interaction-free measurement (IFM) where both the probe and the object are quantum particles. We argue that in this case the description of the measurement…
