Add a convenient state preparation for computational basis states #289

cgogolin · 2018-11-28T16:20:13Z

One thing that is great about ProjectQ is that it has many convenience functions and gates already built in. One thing that I was missing was an easy way to prepare computational basis states.

Inspired by #279 this PR adds a simple BasisState state preparation gate that can be feed an array of 0s and 1s and prepares the corresponding computational basis state (if executed right at the beginning of the circuit, while the system is in state |0>) by applying PauliX gates to the respective qubits.

Please have a look and see if you would find that a useful addition to ProjectQ.

Thanks @cgogolin for this PR!

I have a few minor suggestions:

Change the name to something like "FlipBits", to make it clear that this gate can be used for more than just preparing basis states
Support integers, strings, and lists of bool or [0/1] as input
Remove the additional note in the documentation of StatePreparation: The statement is true for all high-level gates since gates on current hardware are very noisy

improved unit test

reverted accidental change change from BasiGate to FlipBits in _simulator_test.py

cgogolin · 2018-12-11T13:59:36Z

All suggested changes implemented with the latest commits.

I am now no longer sure whether this Gate actually fits in _state_prep.py. Shall I rather move it to _gates.py?

thomashaener · 2018-12-11T19:18:01Z

Great, thanks! Yes, _gates.py would be a better fit.

cgogolin · 2018-12-14T10:09:51Z

Done. From my side this is now read to merge.

thomashaener

Thanks a lot 🥇 ! I have added a few comments / suggestions.
Afterwards we'll go ahead and merge.

projectq/ops/_gates.py

added unit test

…han len(qureg)

cgogolin · 2018-12-17T16:40:37Z

I have further added a unit test that checks that FlipBits can actually be applied to various forms of quregs and arrays of qubits. I think it is good to have that, as we are calling make_tuple_of_qureg() directly.

thomashaener

Thanks a lot for making these changes! 👍
One can now simplify the implementation quite a bit. Please let me know what you think and if you have time to make the changes. If not, I can also quickly do them myself. Thanks!

projectq/ops/_gates.py

made simulator test more stringent

raise ValueError on application to non-trivial tuples of qubits and added test of that removed specification of length of input list from doc string because it no longer applies

projectq/ops/_gates.py

… and the tests

thomashaener

@cgogolin thanks for making these changes!
Sorry that I didn't notice this before, but the docs are no longer up-to-date and it would be great if you could resolve pep8 issues. Also, I would put all tests for FlipBits into _gates_test.py.

Then it's ready to be merged 🎊

projectq/ops/_gates.py

updated doc strings

cgogolin · 2018-12-21T13:09:00Z

If I move the execution tests from _simulator_test.py to _gate_test.py (that what you are asking for, right?) I also need to copy over the sim fixture and get_available_simulators(). Do you really want that or is there a way that I don't see?
I have tried to pylint my part of _gate.py. It now only complains about XGate() | qubit being assigned to nothing, but you don't seem to manually disable this in the other source files.

thomashaener · 2018-12-21T14:03:13Z

Thanks!

Yes, this is what I meant. You can just do eng = MainEngine(), which will have a simulator as the default backend (C++ if available, else Python).

Assignment to nothing: That's fine. I meant running the pep8-tool. After your update, the only complaints that are left are lines being too long, backslashes that can be removed, and too many/not enough blank lines.

cgogolin · 2018-12-21T14:59:00Z

Ah! Tests moved...

I have taken the liberty to also pep8 _qubit_operator.py and _state_prep.py.

From my side this is now done, I think. Puh, that was a lot of back and forth for a PR that I thought would be trivial. Thanks for your help and patience! It would be great if things like pep8 could be run as automatic tests on Travis....

Where does this SelfInverseGate come from?

I removed it, hope that's fine.
