cqgate: A controlled single qubit gate

Description

This class represents a generic controlled gate

Slots

bits

Integer. Integer vector of bits. The first is the control bit, the second the target bit.

gate

sqgate. The single qubit gate.

Details

The qubits are counted from 1 to nbits starting with the least significant bit.

Examples

x <- H(1) * qstate(nbits=2)
## application of the CX (CNOT) gate to bit 1,2
z <- cqgate(bits=c(1L, 2L), gate=X(2L)) * x
z
## the same as, but differently implemented
z <- CNOT(c(1,2)) * x
z
