Abstract

We report a four qubit polynomial invariant that quantifies genuine four-body correlations.The four qubit invariants are obtained from transformation properties of three qubit invariants under a local unitary on the fourth qubit.

The relation between tangle and local unitary invariants for pure three and four-qubit states

Xin-Wei Zha, Yunguang Zhang, Jianxia Qi +1 more

A new form of local unitary (LU) transformation invariant is given for multi-qubit states . The general relation between tangle and the LU transformation invariant of pure three and four-qubit states is given. We find that the tangle actually is a special LU transformation invariant. Furthermore, the tangle is a important local unitary (LU) transformation invariant which is a nessesary condition for maximally multi-qubit entangled state.

On local invariants of pure three-qubit states

Anthony Sudbery

We study invariants of three-qubit states under local unitary transformations, i.e. functions on the space of entanglement types, which is known to have dimension six. We show that there is no set of six algebraically independent polynomial invariants of degree ⩽ 6, and find such a set with maximum degree eight. We describe an intrinsic definition of a canonical state on each orbit, and discuss the (non-polynomial) invariants associated with it.

Upper bound on three-tangles of reduced states of four-qubit pure states

S. Shelly Sharma, Naresh Kumar Sharma

Closed formulas for upper bounds on three-tangles of three-qubit reduced states in terms of three-qubit--invariant polynomials of pure four-qubit states are obtained. Our results offer tighter constraints on total three-way entanglement of a given qubit with the rest of the system than those used by Regula et al. [Phys. Rev. Lett. 113, 110501 (2014) and Phys. Rev. Lett. 116, 049902(E) (2016)] to verify monogamy of four-qubit quantum entanglement.

Unitary invariants and classification of four-qubit states via negativity fonts

S. Shelly Sharma, Naresh Kumar Sharma

Local unitary invariance and the notion of negativity fonts are used as the principal tools to construct four-qubit invariants of degree 8, 12, and 24. A degree-8 polynomial invariant that is nonzero on pure four-qubit states with four-body quantum correlations and zero on all other states is identified. Classification of four-qubit states into seven major classes, using criteria based on the nature of correlations, is discussed.

Local unitary invariants of generic multiqubit states

Naihuan Jing, Shao-Ming Fei, Ming Li +2 more

We present a complete set of local unitary invariants for generic multiqubit systems which gives necessary and sufficient conditions for two states being local unitary equivalent. These invariants are canonical polynomial functions in terms of the generalized Bloch representation of the quantum states. In particular, we prove that there are at most 12 polynomial local unitary invariants for two-qubit states and at most 90 polynomials for three-qubit states. Comparison with Makhlin's 18 local unitary invariants is given for two-qubit systems.
