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…
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…
Ordering the processes with indefinite causal order
Stanislav Filatov, Marcis Auzinsh
We show a method of describing processes with indefinite causal order (ICO) by a definite causal order. We do so by relabeling the processes that take place in the circuit in accor…
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…
