◆ CUniformParityRZ()

void Qrack::QEngineCPU::CUniformParityRZ	(	const bitLenInt *	controls,
		bitLenInt	controlLen,
		bitCapInt	mask,
		real1_f	angle

virtual

If the controls are set and the target qubit set parity is odd, this applies a phase factor of \(e^{i angle}\).

If the controls are set and the target qubit set parity is even, this applies the conjugate, \(e^{-i angle}\). Otherwise, do nothing if any control is not set.

Implements Qrack::QParity.

◆ ForceM()

		bitLenInt	length,
		const bool *	values,
		bool	doApply = `true`
	)

virtual

Bit-wise apply measurement gate to a register.

Reimplemented in Qrack::QEngine.

◆ ForceMReg()

	)

virtual
