New to Ocean? The following sections describe how to install Ocean tools, what they are and how they fit together, and give examples of using them to solve hard problems on a D-Wave quantum computer.
Initial Set Up¶
Install the tools and configure for running on a D-Wave system (QPU) or locally (CPU/GPU).
Overview of Ocean Software¶
Learn how problems are formulated for solution on D-Wave systems using Ocean tools.
See how Ocean tools are used with these end-to-end examples.
- Large Map Coloring demonstrates out-of-the-box solving of an arbitrary-sized problem.
- Vertex Cover solves a small graph problem.
- Constrained Scheduling solves a small constraint satisfaction problem.
- Boolean NOT Gate mathematically formulates a BQM for a two-variable problem.
- Boolean AND Gate demonstrates programming the QPU more directly (minor-embedding).
Copy (clone) open-source code to run demos of solving known problems on a D-Wave system.
Demonstrates the use of the D-Wave system to solve circuit fault diagnosis, the problem of identifying a minimum-sized set of components that, if faulty, explains an observation of incorrect outputs given a set of inputs.
Demonstrates the use of the D-Wave system to factor numbers in an entirely new way, by turning a multiplication circuit into a constraint satisfaction problem that allows the quantum computer to compute inputs from a predefined output. Essentially, this means running the multiplication circuit in reverse.
Demonstrates the use of the D-Wave system for analyzing the structural imbalance on a signed social network. This demo calculates and shows structural imbalance for social networks of militant organization based on data from the Stanford Militants Mapping Project.
This guide in the System Documentation introduces the D-Wave quantum computer, provides some key background information on how the system works, and explains how to construct a simple problem that the system can solve.
This guide for more advanced users has an opening chapter of illustrative examples that explain the main steps of solving problems on the D-Wave system through two “toy” problems.
Leap includes Jupyter Notebooks that provide additional tutorial examples and a framework to help you develop your own code.
