A complete hierarchy for the pure state marginal problem in quantum mechanics

چکیده

Clarifying the relation between whole and its parts is crucial for many problems in science. In quantum mechanics, this question manifests itself marginal problem, which asks whether there a global pure state some given marginals. This problem arises contexts, ranging from chemistry to entanglement theory error correcting codes. paper, we prove correspondence of separability problem. Based on this, describe sequence semidefinite programs can decide marginals are compatible with state. As an application, that existence multiparticle absolutely maximally entangled states dimension equivalent explicitly two-party Finally, show codes parameters also be interpreted as hence, our complete hierarchy used.

Gaussian quantum marginal problem

The quantum marginal problem asks what local spectra are consistent with a given spectrum of a joint state of a composite quantum system. This setting, also referred to as the question of the compatibility of local spectra, has several applications in quantum information theory. Here, we introduce the analogue of this statement for Gaussian states for any number of modes, and solve it in genera...

Quantum Brachistochrone problem and the geometry of the state space in pseudo-Hermitian quantum mechanics.

A non-Hermitian operator with a real spectrum and a complete set of eigenvectors may serve as the Hamiltonian operator for a unitary quantum system provided that one makes an appropriate choice for the defining the inner product of physical Hilbert state. We study the consequences of such a choice for the representation of states in terms of projection operators and the geometry of the state sp...

Triangleland. Ii. Quantum Mechanics of Pure Shape

Relational particle models are of value in the absolute versus relative motion debate. They are also analogous to the dynamical formulation of general relativity, and as such are useful for investigating conceptual strategies proposed for resolving the problem of time in quantum general relativity. Moreover, to date there are few explicit examples of these at the quantum level. In this paper I ...

Minimal Irreversible Quantum Mechanics: Pure States Formalism

It is demonstrated that, making minimal changes in ordinary quantum mechanics, a reasonable irreversible quantum mechanics can be obtained. This theory has a more general spectral decompositions, with eigenvectors corresponding to unstable states that vanish when t → ∞. These ”Gamov vectors” have zero norm, in such a way that the norm and the energy of the physical states remain constant. The e...
