Getting started with the D-Wave(TM) Quantum Computer Solver API C Package
2+
=========================================================================
3+
4+
Version @SAPI_VERSION@
5+
6+
This package includes a header file (dwave_sapi.h) and a shared library:
7+
* Linux: libdwave_sapi.so
8+
* OSX: libdwave_sapi.dylib
9+
* Windows: dwave_sapi.dll (and import library dwave_sapi.lib)
10+
11+
In order to connect to the D-Wave(TM) Quantum Computer Solver API, you will
12+
need two pieces of information: the SAPI URL and an authentication token.
13+
The SAPI URL is listed on the "Solver API" page of the web user interface.
14+
Authentication tokens are also obtained from the web user interface: click
15+
on "API Tokens" in the menu under your user name.
16+
17+
You can find some example code in the examples subdirectory.
18+
