QMASM: A Quantum Macro Assembler

Description

QMASM fills a gap in the software ecosystem for D-Wave's adiabatic quantum computers by shielding the programmer from having to know system-specific hardware details while still enabling programs to be expressed at a fairly low level of abstraction. It is therefore analogous to a conventional macro assembler and can be used in much the same way: as a target either for programmers who want a great deal of control over the hardware or for compilers that implement higher-level languages.

N.B. This tool used to be called "QASM" but was renamed to avoid confusion with MIT's QASM, which is used to describe quantum circuits (a different model of quantum computation from what the D-Wave uses) and the IBM Quantum Experience's QASM (now OpenQASM) language, also used for describing quantum circuits.

Installation

QMASM is written in Python. The latest release can be downloaded and installed from PyPI via

pip install qmasm

Alternatively, QMASM can be installed manually from GitHub using the standard Setuptools installation mechanisms. For example, use

python setup.py install

to install QMASM in the default location and

python setup.py install --prefix=/my/install/directory

to install elsewhere.

Documentation

Documentation for QMASM can be found on the QMASM wiki.

QMASM (then known as QASM) is discussed in the following publication:
