Quantum separability, time reversal and canonical decompositions
نویسندگان
چکیده
We propose an interpretation of quantum separability based on a physical principle: local time reversal. It immediately leads to a simple characterization of separable quantum states that reproduces results known to hold for binary composite systems and which thereby is complete for low dimensions. We then describe a constructive algorithm for finding the canonical decomposition of separable and non separable mixed states of dimensions 2x2 and 2x3. 03.65.Bz, 42.50.Dv, 89.70.+c Typeset using REVTEX

Separability condition for composite systems of distinguishable fermions
We study characterization of separable (classically correlated) states for composite systems of distinguishable fermions. In the computation of entanglement formation for such systems where located subsystems are coupled by the canonical anticommutation relations (not by tensor product), the state decompositions to be taken should respect the univalence superselection rule. (The usual entanglem...
متن کاملTime reversal and n-qubit canonical decompositions
On pure states of n quantum bits, the concurrence entanglement monotone returns the norm of the inner product of a pure state with its spin-flip. The monotone vanishes for n odd, but for n even there is an explicit formula for its value on mixed states, i.e., a closed-form expression computes the minimum over all ensemble decompositions of a given density. For n even a matrix decomposition n=k1...
متن کاملInfinite-dimensional versions of the primary, cyclic and Jordan decompositions
The famous primary and cyclic decomposition theorems along with the tightly related rational and Jordan canonical forms are extended to linear spaces of infinite dimensions with counterexamples showing the scope of extensions.
متن کاملReduction criterion for separability
We introduce a separability criterion based on the positive map #:$ ̃(Tr $)!$ , where $ is a trace-class Hermitian operator. Any separable state is mapped by the tensor product of # and the identity into a nonnegative operator, which provides a simple necessary condition for separability. This condition is generally not sufficient because it is vulnerable to the dilution of entanglement. In the ...
متن کاملCanonical Form and Separability of PPT States on Multiple Quantum Spaces
By using the “subtracting projectors” method in proving the separability of PPT states on multiple quantum spaces, we derive a canonical form of PPT states in C1 ⊗CK2 ⊗· · ·⊗CKm ⊗CN composite quantum systems with rank N , from which a sufficient separability condition for these states is presented. As the key resource in quantum information processing [1], quantum entanglement has resulted in t...
