This is because the paths are now distinguishable. The circles in Figure 3 represent our measurements for this case. We note that we did not measure the ...

To work with this constraint, we want a universal set of quantum gates that we can use to build more complex circuits, just like AND, OR, and NOT in classical computers. ...

In a non-fixed causality structure, the sequence of time steps has no interpretable meaning. In our macroscopic world, events and processes are distinguishable in ...

QUANTUM MEASURES and INTEGRALS

Since 1994 a considerable amount of literature has been devoted to this subject [1, 3, 5, 9, 10, 13, 15] and more recently a quantum integral has been introduced [6, ...
