Geometry of Two-Qubit State and Intertwining Quaternionic Conformal Mapping Under Local Unitary Transformations
نویسنده
چکیده
In this paper the geometry of two-qubit systems under local unitary group SO(2) ⊗ SU(2) is discussed. It is shown that the quaternionic conformal map intertwines between this local unitary subgroup of Sp(2) and the quaternionic Möbius transformation which is rather a generalization of the results of Lee et al (2002 Quantum Inf. Process. 1 129).

In this paper we are going to calculate the correlation function and Bell'sinequality for three qubit W state under the Lorentz transformations. This survey is basedon the introduction of two different expressions of spin observable were presented byLee-Young and Kim-Son.
متن کاملInvariants for a Class of Nongeneric Three-qubit States
We investigate the equivalence of quantum states under local unitary transformations. A complete set of invariants under local unitary transformations is presented for a class of non-generic three-qubit mixed states. It is shown that two such states in this class are locally equivalent if and only if all these invariants have equal values for them. PACS numbers: 03.67.-a, 02.20.Hj, 03.65.-w
متن کاملOn local gamma factors for orthogonal groups and unitary groups
In this paper, we find a relation between the proportionality factors which arise from the functional equations of two families of local Rankin-Selberg convolutions for irreducible admissible representations of orthogonal groups, or unitary groups. One family is that of local integrals of the doubling method, and the other family is that of local integrals expressed in terms of sph...

متن کاملQuantum geometry of the Cartan control problem
The Cartan control problem of the quantum circuits discussed from the differential geometry point of view. Abstract unitary transformations of SU(2n) are realized physically in the projective Hilbert state space CP (2n − 1) of the n-qubit system. Therefore the Cartan decomposition of the algebra AlgSU(2n −1) into orthogonal subspaces h and b such that [h, h] ⊆ h, [b, b] ⊆ h, [b, h] ⊆ b is state...
