Improve error messaging for the katas that allow it

7

Several katas could have better error messaging: - [x] Superposition : the test harness could log the actual state of the system after prep vs the expected state before asserting...

Improve Simon's algorithm kata

1

Simon's algorithm kata differs from the others in that Simon's algorithm has non-trivial classical processing involved, but the tasks of the kata cover only the (relatively simple) quantum part of...

Create troubleshooting guide

1

There is a set of "standard" things that can go wrong when running the katas, and it makes sense to write them down in a single place, so that a...

BayesianPEIsCorrect test fails probabilistically

1

**Describe the bug** [`BayesianPEIsCorrect` test](https://github.com/microsoft/Quantum/blob/8ac8d28959526f7f0f392b27116e8e00fb205d8d/samples/tests/sample-tests/BayesianPETests.qs) fails probabilistically. Similarly to https://github.com/microsoft/QuantumLibraries/issues/444, we should fix the seed used in the test, or run several tries in a loop and say that the...

Some READMEs are outdated (new samples missing)

11

Here are some examples: * [Root README](https://github.com/microsoft/Quantum/blob/main/README.md) is missing machine learning category of samples * [README in algorithms](https://github.com/microsoft/Quantum/blob/main/samples/algorithms/README.md) is missing `repeat-until-success` and `sudoku-grover` * [README in diagnostics](https://github.com/microsoft/Quantum/blob/main/samples/diagnostics/README.md) is missing `dumping`...

State visualizer sample readme is outdated

1

**Describe the bug** The readme at https://github.com/microsoft/Quantum/tree/main/samples/runtime/state-visualizer looks out of sync with the code. The instructions suggest to edit Program.qs file, looking for QsMain operation, and neither exist. (Instead, the...

**Describe the bug** I'm observing several odd behaviors, I'm not sure which of them are bugs and which are expected, so I'll report them all at once without unentangling them....

Highlight "size" as a keyword in array literal context

1

**Is your feature request related to a problem? Please describe.** Q# Jupyter Notebooks don't highlight "size" as a keyword. **Describe the solution you'd like** Highlight "size" as a keyword in...

**Describe the bug** Q# Boolean values `true` and `false` are printed as `True` and `False`, in incorrect capitalization. **Expected behavior** The values are printed the way they are defined in...

New array syntax fails for arrays within tuples

1

**Describe the bug** Replacing the code based on the warning about deprecated syntax (see repro below) produces a runtime error Unhandled exception. System.InvalidCastException: Unable to cast object of type 'System.ValueTuple`2[Microsoft.Quantum.Simulation.Core.QArray`1[System.Int64],Microsoft.Quantum.Simulation.Core.QRange]'...
