Digital Bloqade

The digital submodule of Bloqade, called bloqade-circuit defines a set of embedded domain-specific languages (eDSLs) that can be used to define digital quantum programs. These programs are intended for both simulation and to be run on hardware. This package is open source and can be found on GitHub.

Please refer to the Dialects and Kernels section of this documentation for an overview over the most important eDSLs. The infrastructure behind these compilers is built on top of Kirin.

It is easiest to learn how to use this package by checking out the examples & tutorials section, where we show how you can build and study different quantum programs written in different DSLs. You can also find the corresponding scripts in jupytext format at the bloqade repository under docs/digital/examples/.

Finally, if you want the full details on the API, please refer to the API reference documentation.

Installation

The package comes as a submodule of Bloqade, so you can just run

pip install bloqade

in order to obtain it.

Sometimes, you may want to reduce the number of dependencies, in which case you can also only install the submodule

pip install bloqade-circuit

Note, that bloqade-circuit also has some optional dependencies, which you may want to install. For example

pip install bloqade-circuit[cirq,qasm2,stim]

TL;DR

Here's a GHZ preparation circuit written in the squin dialect:

from bloqade import squin

@squin.kernel
def ghz(n: int):
    q = squin.qubit.new(n)

    squin.gate.h(q[0])

    for i in range(1, n):
        squin.gate.cx(q[i - 1], q[i])

    return squin.qubit.measure(q)

Here are some more examples.
