ChangeBasisNode

class samplomatic.samplex.nodes.ChangeBasisNode(register_name: str, basis_change: BasisChange, basis_ref: str, num_subsystems: int)

Bases: SamplingNode

A node that instantiates a basis changing virtual register for a given measurement.

Parameters:

• register_name – The name of the register to instantiate.

• basis_change – The basis change to implement.

• basis_ref – Unique identifier of the basis to use.

• num_subsystems – The number of subsystems this node generates gates for.

Attributes Summary

outgoing_register_type

The virtual gate type of outgoing registers.

Methods Summary

get_style()	Return the style of this node when plotted.
instantiates()	Return a manifest of new virtual registers that this node instantiates.
sample(registers, rng, inputs, ...)	Sample this node.

outgoing_register_type

Methods Documentation

get_style()

Return the style of this node when plotted.

instantiates()

Return a manifest of new virtual registers that this node instantiates.

Note

• To change the type or size of a register, both instantiate and remove it.

• Do not specify reads_from() or writes_to() for an instantiated register, these powers are implicit.

sample(registers, rng, inputs, num_randomizations)

Sample this node.

Parameters:

• registers – Where to sample into.

• rng – A randomness generator.

• inputs – Inputs of the sampling program.

• num_randomizations – How many randomizations to draw.
