Q# is an open-source, high-level programming language for developing and running quantum algorithms. The qsharp package for Python provides interoperability with the Q# interpreter, making it easy to simulate Q# programs within Python.

To install the Q# language package, run:

pip install qsharp

First, import the qsharp module:

import qsharp

Then, use the %%qsharp cell magic to run Q# directly in Jupyter notebook cells:

%%qsharp

import Std.Diagnostics.*;

@EntryPoint()
operation BellState() : Unit {
    use qs = Qubit[2];
    H(qs[0]);
    CNOT(qs[0], qs[1]);
    DumpMachine();
    ResetAll(qs);
}

BellState()

This library sends telemetry. Minimal anonymous data is collected to help measure feature usage and performance. All telemetry events can be seen in the source file telemetry_events.py.

To disable sending telemetry from this package, set the environment variable QSHARP_PYTHON_TELEMETRY=none
