Member Function Documentation

CUniformParityRZ()

virtual void Qrack::QParity::CUniformParityRZ ( const std::vector< bitLenInt > &  controls, const 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::QUnit, Qrack::QStabilizerHybrid, Qrack::QPager, Qrack::QHybrid, Qrack::QEngineOCL, Qrack::QEngineCUDA, Qrack::QEngineCPU, Qrack::QBdtHybrid, and Qrack::QBdt.

ForceMParity()

virtual bool Qrack::QParity::ForceMParity ( const 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.

MParity()

virtual bool Qrack::QParity::MParity ( const bitCapInt &  mask )

inlinevirtual

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

ProbParity()

virtual real1_f Qrack::QParity::ProbParity ( const bitCapInt &  mask )

pure virtual

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

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

UniformParityRZ()

virtual void Qrack::QParity::UniformParityRZ ( const 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::QPager, Qrack::QHybrid, Qrack::QEngineOCL, Qrack::QEngineCUDA, Qrack::QEngineCPU, and Qrack::QBdtHybrid.
