Abstract

QBism is an interpretation of quantum mechanics, proposed by certain physicists that interprets quantum probabilities as subjective Bayesian probabilities, whence its name. By attempting to avoid experientially unfulfilled speculations about what exists prior to measurement, QBism seems to make a close encounter with the phenomenological method. What follows is an interview with QBism’s founder and principal champion, the physicist Christopher Fuchs.
