Using the relativistic arrival-time distribution of Kijowski it is argued that the peculiar form of the spatial nonlocality—but not the nonlocality itself—of the “standard” distribution is an artifact of the nonrelativistic approximation. Als

The paradoxical properties of the N -box problem ( N ⩾ 3 ) are dispelled by the straightforward exercise of constructing, for an arbitrary pre-selected state with N nonzero orthogonal components, the corresponding (unique) post-selected state such

The “main claim” of the Comment is “alleged paradoxes dissolve by taking seriously the standard interpretation of quantum mechanics”. In fact, the authors merely suggest possible loopholes which I argue are ineffective, not addressing the spa

The spatial nonlocality of the “standard” arrival-time distribution is analyzed theoretically for an arbitrary initial wave function and found to be of an unusual nature.

The “standard” approach to times of arrival advocated by Equsquiza, Muga and Baute associates arrivals from the left (right) with positive (negative) wavenumber components of the wave function at the instant of arrival. Elementary arguments and c

For a Schrodinger wave function, the part of the phase that depends only on time disappears in the construction of the corresponding Wigner phase-space (quasi)distribution function. Despite this, it can be recovered from the Wigner function using the

The arrival time is a simple classical concept, very common in laboratory practice. This review describes theoretical problems encountered in trying to obtain a quantum mechanical counterpart and the solutions proposed. A summary of current experimen

The most general classical expression defining the first passage time is given in terms of the absorption rate with perfectly absorbing boundary conditions. Its operational use in quantum mechanics is discussed. In particular, in the quantum case an

In a recent paper Grot, Rovelli, and Tate (GRT) [Phys. Rev. A 54, 4676 (1996)] derived an expression for the probability distribution $\ensuremath{\pi}(T;X)$ of intrinsic arrival times $T(X)$ at position $x=X$ for a quantum particle with initial wave
