netqasm.sdk.compiling¶

Transpilation of subroutines from one flavour to another.

This module contains the SubroutineCompiler interface which is a base class for transpilers that can convert a NetQASM subroutine into a subroutine with a specific flavour.

class netqasm.sdk.compiling.SubroutineCompiler(subroutine, debug=False)¶

Bases: abc.ABC

Parameters

subroutine (Subroutine) –
debug (bool) –

abstract compile()¶

Compile the subroutine into one with a specific flavour.

Return type: Subroutine

class netqasm.sdk.compiling.NVSubroutineCompiler(subroutine, debug=False)¶

Bases: netqasm.sdk.compiling.SubroutineCompiler

A transpiler that converts a subroutine with the vanilla flavour to a subroutine with the NV flavour.

Parameters: subroutine (Subroutine) –

get_reg_value(reg)¶

Get the value of a register at this moment

Parameters: reg (Register) –
Return type: Immediate

get_unused_register()¶

Naive approach: try to use Q0 if possible, otherwise Q1, etc.

Return type: Register

swap(lineno, electron, carbon)¶

Swap the states of the electron and a carbon. See https://gitlab.tudelft.nl/qinc-wehner/netqasm/netqasm-docs/-/blob/master/nv-gates-docs.md for the circuit.

Parameters

lineno (Optional[HostLine]) –
electron (Register) –
carbon (Register) –

Return type

List[NetQASMInstruction]

compile()¶

Very simple compiling pass: iterate over all instructions once and rewrite them in-line. While iterating, keep track of which registers are in use and what their values are.

Return type: Subroutine

netqasm.sdk.compiling.get_hardware_num_denom(instr)¶

Parameters: instr (RotationInstruction) –
Return type: Tuple[Immediate, Immediate]
