Against the tyranny of ‘Pure States’ in quantum theory
(Springer, 2021-03-22)
We argue that the notion of pure sate within Standard Quantum Mechanics is presently applied within the specialized literature in relation to two mutually inconsistent definitions. While the first (operational purity) ...
Pure spinor partition function and the massive superstring spectrum
(Int School Advanced Studies, 2008-08-01)
We explicitly compute up to the fifth mass-level the partition function of ten-dimensional pure spinor worldsheet variables including the spin dependence. After adding the contribution from the (x(mu), theta(alpha), p(alpha)) ...

Linearly independent pure-state decomposition and quantum state discrimination

Normalization procedure for relaxation studies in NMR quantum information processing
(SPRINGER, 2010)
NMR quantum information processing studies rely on the reconstruction of the density matrix representing the so-called pseudo-pure states (PPS). An initially pure part of a PPS state undergoes unitary and non-unitary ...
Multipartite quantum correlations in open quantum systems
(2013-04-01)
In this paper, we present a measure of quantum correlation for a multipartite system, defined as the sum of the correlations for all possible partitions. Our measure can be defined for quantum discord (QD), geometric quantum ...

Pure Spinors in AdS and Lie Algebra Cohomology
(Springer, 2014-10-01)
We show that the BRST cohomology of the massless sector of the Type IIB superstring on AdS(5) x S (5) can be described as the relative cohomology of an infinite-dimensional Lie superalgebra. We explain how the vertex ...
Spontaneous recoherence of quantum states after decoherence
(SPRINGER, 2010)
In this work, we identify the set of time-dependent pure states building the statistical mixture to which a system, initially in a pure state, is driven by the reservoir. This set of time-dependent pure states, composing ...
