  • We study the sequential product the operation pāˆ—q=pqp on the set of effects, [0, 1]š’œ, of a von Neumann algebra š’œ that represents sequential measurement of first p and then q. In their work [J. Math. Phys. 49(5), 052106 (2008)], Gudder and Latremoliere give a list of axioms based on physical grounds that completely determines the sequential product on a von Neumann algebra of type I, that is, a von Neumann algebra ā„¬(ā„‹) of all bounded operators on some Hilbert space ā„‹. In this paper we give aā€¦Ā CONTINUE READING
