Path summation and quantum measurements
D. Sokolovski, R. Sala Mayato
We propose a general theoretical approach to quantum measurements based on the path (histories) summation technique. For a given dynamical variable A, the Schrödinger state of a sy…

"Superluminal" tunnelling, quantum measurements and the speed of information transfer
D. Sokolovski, A. Z. Msezane, V. R. Shaginyan
We exploit the analogy between tunnelling across a potential barrier and Aharonov's weak measurements to resolve the long standing paradox between the impossibility to exceed the s…

Why relativity allows quantum tunnelling to 'take no time'?
D. Sokolovski
In quantum tunnelling, what appears an infinitely fast barrier traversal can be explained in terms of an Aharonov-like weak measurement of the tunnelling time, in which the role of…
