Phenomenological quantum mechanics: II. Deducing the formalism from experimental observations
Piotr Szańkowski, Davide Lonigro, Fattah Sakuldee +2
We propose an exercise in which one attempts to deduce the formalism of quantum mechanics solely from phenomenological observations. The only assumed inputs are the multi-time prob…
Phenomenological quantum mechanics: I. Phenomenology of quantum observables
Piotr Szańkowski, Davide Lonigro, Fattah Sakuldee +2
We propose an exercise in which one attempts to deduce the formalism of quantum mechanics solely from phenomenological observations. The only assumed inputs are obtained through se…
Double or nothing: a Kolmogorov extension theorem for multitime (bi)probabilities in quantum mechanics
Davide Lonigro, Fattah Sakuldee, Łukasz Cywiński +2
The multitime probability distributions obtained by repeatedly probing a quantum system via the measurement of an observable generally violate Kolmogorov's consistency property. Th…
Objectivity of classical quantum stochastic processes
Piotr Szańkowski, Łukasz Cywiński
We investigate what can be concluded about a quantum system when sequential quantum measurements of its observable -- a prominent example of the so-called quantum stochastic proces…
Characterization of a quasi-static environment with a qubit
Fattah Sakuldee, Łukasz Cywiński
We consider a qubit initalized in a superposition of its pointer states, exposed to pure dephasing due to coupling to a quasi-static environment, and subjected to a sequence of sin…
Decoherence-assisted detection of entanglement of two qubit states
Jan Krzywda, Piotr Szańkowski, Jan Chwedeńczuk +1
We show that the decoherence, which in the long run destroys quantum features of a system, can be used to reveal the entanglement in a two-qubit system. To this end, we consider a…
