The Quantum::Superpositions module adds two new operators to Perl: any and
|
||
|
|
all.
|
||
|
|
|
||
|
|
Each of these operators takes a list of values (states) and superimposes
|
||
|
|
them into a single scalar value (a superposition), which can then be
|
||
|
|
stored in a standard scalar variable.
|
||
|
|
|
||
|
|
The any and all operators produce two distinct kinds of superposition. The
|
||
|
|
any operator produces a disjunctive superposition, which may (notionally)
|
||
|
|
be in any one of its states at any time, according to the needs of the
|
||
|
|
algorithm that uses it.
|
||
|
|
|
||
|
|
In contrast, the all operator creates a conjunctive superposition, which
|
||
|
|
is always in every one of its states simultaneously.
|
||
|
|
|
||
|
|
Superpositions are scalar values and hence can participate in arithmetic
|
||
|
|
and logical operations just like any other type of scalar. However, when
|
||
|
|
an operation is applied to a superposition, it is applied (notionally) in
|
||
|
|
parallel to each of the states in that superposition.
