Compatibility of quantum measurements: coexistence of qubit observables

One of key differences of quantum mechanics and classical physics is the inability to perform all pairs of measurements simultaneously in quantum domain. The most prominent examples are position-momentum observables or spin components. In the talk I aim to show the analysis of simultaneous measurements (observables) in simplest qubit case. The talk will also touch generalization of the notion of joint measurability (and coexistence) of observables to more general quantum measurement devices.
