Joint measurability in Lindbladian open quantum systems
Jukka Kiukas, Pekka Lahti, Juha-Pekka Pellonpää
We study joint measurability of quantum observables in open systems governed by a master equation of Lindblad form. We briefly review the historical perspective of open systems and…
An attempt to understand relational quantum mechanics
Pekka Lahti, Juha-Pekka Pellonpää
We search for a possible mathematical formulation of some of the key ideas of the relational interpretation of quantum mechanics and study their consequences. We also briefly overv…
Complementary observables in quantum mechanics
Jukka Kiukas, Pekka Lahti, Juha-Pekka Pellonpää +1
We review the notion of complementarity of observables in quantum mechanics, as formulated and studied by Paul Busch and his colleagues over the years. In addition, we provide furt…
Number and phase: complementarity and joint measurement uncertainties
Pekka Lahti, Juha-Pekka Pellonpää, Jussi Schultz
We show that number and canonical phase (of a single mode optical field) are complementary observables. We also bound the measurement uncertainty region for their approximate joint…
An axiomatic basis for quantum mechanics
Gianni Cassinelli, Pekka Lahti
In this paper we use the framework of generalized probabilistic theories to present two sets of basic assumptions, called axioms, for which we show that they lead to the Hilbert sp…
Measurement Uncertainty: Reply to Critics
P. Busch, P. Lahti, R. F. Werner
In a recent publication [PRL 111, 160405 (2013)] we proved a version of Heisenberg's error-disturbance tradeoff. This result was in apparent contradiction to claims by Ozawa of hav…
