◆ CUniformParityRZ()

virtual void Qrack::QParity::CUniformParityRZ ( const bitLenInt controls,
bitLenInt  controlLen,
bitCapInt  mask,
real1_f  angle 
)
pure 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.

Implemented in Qrack::QStabilizerHybrid, Qrack::QMaskFusion, Qrack::QEngineOCL, Qrack::QEngineCPU, Qrack::QBdt, Qrack::QHybrid, Qrack::QPager, and Qrack::QUnit.

◆ ForceMParity()

virtual bool Qrack::QParity::ForceMParity ( bitCapInt  mask,
bool  result,
bool  doForce = true 
)
pure virtual

Act as if is a measurement of parity of the masked set of qubits was applied, except force the (usually random) result.

PSEUDO-QUANTUM

◆ MParity()

virtual bool Qrack::QParity::MParity ( bitCapInt  mask)
inlinevirtual

Measure (and collapse) parity of the masked set of qubits.

◆ ProbParity()

virtual real1_f Qrack::QParity::ProbParity ( bitCapInt  mask)
pure virtual

Overall probability of any odd permutation of the masked set of bits.

Implemented in Qrack::QMaskFusion, Qrack::QStabilizerHybrid, Qrack::QEngineOCL, Qrack::QHybrid, Qrack::QEngineCPU, Qrack::QPager, Qrack::QBdt, and Qrack::QUnit.

◆ UniformParityRZ()

virtual void Qrack::QParity::UniformParityRZ ( bitCapInt  mask,
real1_f  angle 
)
inlinevirtual

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

If the target qubit set parity is even, this applies the conjugate, e^{-i angle}.

Reimplemented in Qrack::QStabilizerHybrid, Qrack::QMaskFusion, Qrack::QEngineOCL, Qrack::QEngineCPU, Qrack::QHybrid, and Qrack::QPager.
