... (i) For macroscopic particles, ∆x and ∆px will be negligible compared to h x i and h px i. At the same time, the variation of F over the extension of the wave packet will be insignificant, so that h F (x) i = F (h x i), to a very good approximation. In this case, the expectation values h x i and h p ...

The Indivisible Now: why time must be discrete. - Philsci
... To argue for this in a little more detail, firstly consider the essence of time as a sequence of information from the future into the past. The nature of time as a timing mechanism13 is a more mechanical, arbitrary property, and not what I am considering here. Strictly speaking any entangled system ...

An Introduction to Quantum Computation
... These two states are important in their own right. We denote them as |+i and |−i, respectively. For later use, we note that if we apply a Hadamard gate again, we will return to our original qubit. That is, H|+i = 0, and H|−i = 1. Notice that these two states have identical probabilities but differe ...
