“…Vaidman, together with his collaborators, performed an experiment demonstrating a surprising trace of the photons in nested interferometers [ 1 ] (see Figure 1 ). These results became the topic of a very large controversy [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ].…”

The past of the photon in a nested Mach-Zehnder interferometer with an inserted Dove prism is analyzed. It is argued that the Dove prism does not change the past of the photon. Alonso and Jordan correctly point out that an experiment by Danan et al. demonstrating the past of the photon in nested interferometer will show different results when the Dove prism is inserted. The reason, however, is not that the past is changed, but that the experimental demonstration becomes incorrect. The explanation of a signal from the place in which the photon was (almost) not present is given. Bohmian trajectory of the photon is specified.

“…The faint trace will be on all parts of this line, but also in a separate loop disconnected from the line. The prediction of this closed loop, which does not start at the source and does not end at the detector, generated a hot discussion [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] which only intensified [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] after the first experiment with photons [22] confirmed discontinuous trajectories.…”

Do neutrons disagree with photons about where they have been inside an interferometer?

Recent experiments with identically tuned nested Mach-Zehnder interferometers which attempted to observe the location of particles inside these interferometers are analyzed. In spite of claims to the contrary, it is argued that all experiments support the same surprising picture according to which the location of the particles inside the interferometers is not described by continuous trajectories.

“…According to my definition, a pre and postselected particle can be in several places simultaneously, and, moreover, the particle might have disconnected regions of presence. My proposal created a significant controversy, (Li et al, 2013;Vaidman, 2013b;Griffiths, 2016;Vaidman, 2017a;Salih, 2018;Hashmi et al, 2016;Vaidman, 2018;Hashmi et al, 2018;Paneru and Cohen, 2017;Duprey and Matzkin, 2017;Aharonov et al, 2017;Aharonov et al, 2018;Hance et al, 2023b;Vaidman, 2023;Hance et al, 2023a).…”
