“…Quantifiers of the statistical distance and speed of quantum states play an integral role in quantum information theory [10][11][12]. They are used to quantify the distinguishability of quantum states [10,11,13], to understand geometrical aspects of quantum mechanics and quantum phase transitions [12,[14][15][16][17][18][19][20][21][22][23], to quantify initial correlations, information flow * manuel.gessner@ino.it and non-Markovian effects in quantum evolutions [24][25][26][27], to determine the precision of phase estimation [1,3,5,28], to derive limits on the evolution time [29][30][31][32] or on the occurrence of quantum Zeno dynamics [33], and to quantify and detect quantum properties such as coherence [34], quantum correlations and discord [35][36][37][38], uncertainty [39], asymmetry [8,40], or purity [41,42].…”
