The state vector (15.5.2) has the probability given by (15.5.27) of yielding
, and the probability to obtain is calculated with (15.5.28),
(15.5.27)
(15.5.28)
and the new states are
(15.5.29)
and
(15.5.30)
respectively.
15.5.4 Quantum Gates
In Section 15.2 we have explained some concepts that are very important
in classical computation; moreover, we introduce notions about reversible
computing and CM. In this section, we are going to extend such knowledge
to the fi eld of QC. We will start defi ning a quantum gate as follows
(Yansofsky and Mannucci 2008):
“A quantum gate is simply an operator that ...
