## How does D-Wave QB-Solve work?

D-Wave QB-Solve is a quantum computing software platform that provides tools for utilising D-Wave quantum computers to solve optimization and sampling problems. It consists of a Python library for interacting with D-Wave systems and a graphical user interface for displaying and analysing results. QB-Solve can be utilised for a variety of purposes, including machine learning, financial modelling, and logistics optimization.

## How Do You Implement dwave qbsolve with Python?

D-Wave Systems offers a Python library called dwave-ocean-sdk that facilitates the incorporation of quantum computers into Python projects. Using the dwave.inspector.QBSolv() method, the library can execute QUBO (quadratic unconstrained binary optimization) problems.

D-QBSolv Wave’s (Quantum Binary Solver) can be implemented in Python using the D-Wave Ocean SDK (Software Development Kit). The Ocean SDK is a Python library that makes D-Wave quantum computers easy to work with.

Here is an example of using QBSolv in Python to solve a binary quadratic model (BQM):

1.**Install the D-Wave Ocean SDK by running pip install dwave-ocean-sdk**

`pip install dwave-ocean-sdk`

**2.Import the necessary modules:**

`from dwave.system import DWaveSampler, EmbeddingComposite from dwave.cloud import Client`

**3.Use the D-Wave Cloud Client to connect to the D-Wave quantum computer:**

```
client = Client.from_config()
sampler = EmbeddingComposite(DWaveSampler())
```

**4.Describe the binary quadratic model (BQM) you want to solve. For example, the following code describes a simple BQM with two binary variables, x1 and x2:**

```
from dimod import BinaryQuadraticModel
bqm = BinaryQuadraticModel({'x1': -1, 'x2': 2}, {'x1': 1, 'x2': -1}, -1, 'BINARY')
```

**5.Use QBSolv to find the BQM sample with the least amount of energy:**

`response = sampler.sample(bqm, solver='qbsolv', num_reads=100)`

**6.The solution is returned as a dimod response object, which can be used to get the lowest-energy sample and other information about the solution. For example:**

`lowest_energy_sample = response.first.sample`
