const double xacc::AcceleratorBuffer::getExpectationValueZ ( )

virtual

Compute and return the expectation value with respect to the Pauli-Z operator. Here we provide a base implementation based on an ensemble of measurement results. Subclasses are free to implement this as they see fit, ie, for simulators use the wavefunction.

Returns: expVal The expectation value

const std::vector< std::string > xacc::AcceleratorBuffer::getMeasurements ( )

virtual

Return all measurements as bit strings.

Returns: bitStrings List of bit strings.

const std::string xacc::AcceleratorBuffer::name ( ) const

Return this AcceleratorBuffer's name

Returns: name The name of this AcceleratorBuffer

void xacc::AcceleratorBuffer::print ( )

virtual

Print information about this AcceleratorBuffer to standard out.

void xacc::AcceleratorBuffer::print ( std::ostream & stream )

virtual

Print information about this AcceleratorBuffer to the given output stream.

Parameters

stream Stream to write the buffer to.

void xacc::AcceleratorBuffer::resetBuffer ( )

virtual

Reset the stored measured bit strings.

const int xacc::AcceleratorBuffer::size ( ) const

Return the number of bits in this buffer.

Returns: size The number of bits in this buffer
