DaggeredGate

Extends:

BasicGate → DaggeredGate

Wrapper class allowing to execute the inverse of a gate, even when it does not define one.

If there is a replacement available, then there is also one for the inverse, namely the replacement function run in reverse, while inverting all gates. This class enables using this emulation automatically.

A DaggeredGate is returned automatically when employing the getInverse- function on a gate which does not provide a getInverse() member function.

Example:


with Dagger(eng)
MySpecialGate | qubits

will create a DaggeredGate if MySpecialGate does not implement
getInverse. If there is a decomposition function available, an auto-
replacer engine can automatically replace the inverted gate by a call to
the decomposition function inside a "with Dagger"-statement.
