Command/Instruction unification #3862

lcapelluto · 2020-02-18T21:29:51Z

Summary

First part of #3750

Begin command and instruction unification within Pulse. Instructions will migrate into the new instructions submodule of pulse. This begins by moving only the Instruction class. The Instruction command attribute is deprecated in favor of operands, and references to commands are updated.

This is the first of a series of 7 (anticipated) PRs to implement this migration. All other PRs depend on this one.

TODO:

Get details from Thomas about operands

For the reviewer: I made comments near the functions in instructions.py that are altered from the original file.

…will migrate into the new instructions submodule of pulse. This begins by moving only the Instruction class. The Instruction ``command`` attribute is deprecated in favor of ``operands``, and references to commands are updated.

…ommands/__init__ can have a deprecation warning after the rest is implemented

… now just 'duration', and any other operands only exist for an instruction instance

Fix up hash function

This is looking good! I've noted a couple of things I might change, but I am of course open to discussion 😄 .

LGTM! A good start! Looking forward to seeing the rest.

LGTM, just some comments from a quick skimming of the release notes

This should probably be either feature or upgrade (probably feature)

My idea was this one prelude message and then the following 6 PRs would be a list of upgrades with specific details, for example DelayInstruction(Delay(time), channel) => Delay(time, channel)

But I'll defer to your opinion

+    There has been a significant simplification to the style in which Pulse
+    instructions are built.

+    With the previous style, ``Command`` s were called with channels to make


Do you want to use:

Suggested change

With the previous style, ``Command`` s were called with channels to make

With the previous style, :class:`qiskit.pulse.Command`s were called with channels to make

here and in other places were you reference a class?

Not for Command because it wants to disappear

Instruction should though
