public final class CHGate extends TwoQubitGate
Controlled Hadamard (CH) quantum gate.

A two-qubit gate where the target qubit undergoes a Hadamard transformation if the control qubit is |1⟩. The gate matrix in the computational basis {|00⟩, |01⟩, |10⟩, |11⟩} is: 

 [1  0  0   0  ]
 [0  1  0   0  ]
 [0  0  H[0][0] H[0][1]]
 [0  0  H[1][0] H[1][1]]

where H is the Hadamard matrix.
