Three-qubit quantum gates and filters for linear optical quantum-information processing,
We present a linear optical scheme for the implementation of a three-qubit quantum gate that can be considered as a generalization of the two-qubit partial-SWAP gate. The gate leaves unchanged all fully symmetric states of ...

Einstein-Podolsky-Rosen steering and coherence in the family of entangled three-qubit states
Considering the system of three interacting qubits, we analyze four families of states from the point of view of bipartite correlations appearing in two-qubit subsystems of a three-qubit model, such as Ein...

Mixedness, Coherence and Entanglement in a Family of Three-Qubit States
We consider a family of states describing three-qubit systems. We derived formulas showing the relations between linear entropy and measures of coherence such as degree of coherence, first- and second-order correlation functions. We...

Minimal qubit tomography
We present, and analyze thoroughly, a highly symmetric and efficient scheme for the determination of a single-qubit state, such as the polarization properties of photons probabilities, just enough for the determination of the three ...

Two methods for measuring Bell nonlocality via local unitary invariants of two-qubit systems in Hong-Ou-Mandel interferometers
two-qubit state up to local unitaries. We demonstrate that measuring three of the Makhlin's invariants directly one needs to use both two-qubit singlets and threeWe describe a direct method to experimentally ...

W-Class States-Identification and Quantification of Bell-CHSH Inequalities' Violation
We discuss a family of W-class states describing three-qubit systems. For such systems, we analyze the relations between the entanglement measures and the nonlocality parameter for a two-mode mixed state related to the two-qubit...

Optical implementation of the encoding of two qubits to a single qutrit
for encoding two qubits into one qutrit. In this protocol, Alice encodes an arbitrary pure product state of two qubits into a state of one qutrit. Bob can then restore either of the twoencoded qubit states error-free but n...
