We will begin with definitions and examples of the notions of partial trace, partial transpose, completely positive maps and completely entangled . subspaces. . We shall display certain classes of states that can be determined by their partial traces. Entanglement is a powerful resource in Quantum information and communication. Separable states satisfy the Peres test of positivity under partial transpose (PPT) but there is an abundance of non-PPT (NPT) entangled states. Completely entangled subspaces of multipartite quantum systems viz., subspaces of the tensor product of finitely many finite-dimensional Hilbert spaces containing no non-zero product vector, have received attention by many researchers beginning with Bennett et al .

Podolsky. , and Nathan Rosen created a thought experiment that was supposed to show a lack of completeness in quantum mechanics, a relatively recent creation at the time. The thought experiment, later called the EPR paradox after the last names of the creators, was based upon a paradox they saw in the quantum entanglement idea of quantum mechanics regarding the fact that one cannot know observables from different sets. They began by imagining two physical systems that interact when created, so that they will be defined by a single quantum state (Blanton). In other words, one must begin by imagining two entangled particles. Even when separated, the two systems will still be described by the same wave function, no matter the distance between them, as they are still entangled. If someone measures an observable, such as the spin if the systems are photons, of one system, it “will immediately determine the measurement of the corresponding observable in the second system” (Blanton). This applies even at distances that special relativity should prohibit. Imagine that the two systems are light-years apart. According to quantum mechanics, measuring an observable in the first system forces the corresponding observable in the other system into a well-defined state immediately, despite the fact that they are not close enough to have an effect on one another. The information between the two has passed much too fast for the distance under the theory of relativity. This left two options for Einstein, . Recent improvements in SimpleX2. Chael Kruip.
