# Dynex SDK

Dynex provides a qubit-agnostic computing platform designed to unify diverse quantum and quantum-driven compute resources under a single execution and programming environment. The Dynex SDK enables users to access heterogeneous compute modalities through a consistent workflow for optimization, simulation, and probabilistic workloads—without requiring direct exposure to device-specific implementations. It is compatible with PennyLane, IBM Qiskit, OpenQAM, Dimod, PyQUBO, and the Ocean SDK.

## Documentation & Examples

- [Dynex SDK Documentation & API Reference](https://dynex.mintlify.app/introduction)
- [A curated collection of Dynex SDK based example notebooks](https://github.com/Dynex-Development/awesome-dynex)

## Installation

### Install with uv (recommended)

```bash
uv add dynex
```

### Install with pip

```bash
pip install dynex
```

### Install uv

If you don't have `uv` yet:

```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
```

Or via Homebrew on macOS:

```bash
brew install uv
```

## Quick Start

```python
import dynex
import dimod

# Create BQM
bqm = dimod.BinaryQuadraticModel({0: 1.0, 1: -1.0}, {(0, 1): 0.5}, 0.0, 'BINARY')

# Create sampler and sample
model = dynex.BQM(bqm)
sampler = dynex.DynexSampler(model)
sampleset = sampler.sample(num_reads=10)

print(sampleset.first.sample)
```

## Configuration

### Environment Variables

Set credentials via environment variables or `.env` file:

```bash
DYNEX_SDK_KEY=your_sdk_key
DYNEX_GRPC_ENDPOINT=quantum-router-engine-grpc.hz.dynex.co:3000
```

### Compute Backends

Dynex SDK supports three compute backends via the `ComputeBackend` enum:
```python
from dynex import DynexConfig, ComputeBackend

# Using enum (recommended)
config = DynexConfig(compute_backend=ComputeBackend.QPU)

# Using string (also supported)
config = DynexConfig(compute_backend="qpu")
```

#### 1. CPU Backend (Default)

Efficient quantum emulation on CPU providing up to 1,000,000 algorithmic qubits:

```python
config = DynexConfig(compute_backend=ComputeBackend.CPU)
sampler = dynex.DynexSampler(model, config=config)
sampleset = sampler.sample(num_reads=100)
```

#### 2. GPU Backend

GPU-accelerated quantum emulation of up to 1,000,000 algorithmic qubits:

```python
config = DynexConfig(compute_backend=ComputeBackend.GPU)
sampler = dynex.DynexSampler(model, config=config)
sampleset = sampler.sample(num_reads=100)
```

#### 3. QPU Backend

Access to Quantum Processing Units (QPUs), including Dynex's proprietary quantum hardware (Apollo and Zeus series) and integrated third-party QPUs (IBM, IonQ, Rigetti, D-Wave, QuEra and IQM) via Dynex's Qubit-Agnostic Quantum Platform:

```python
from dynex import QPUModel

# Using QPUModel enum (recommended)
config = DynexConfig(
    compute_backend=ComputeBackend.QPU,
    qpu_model=QPUModel.APOLLO_RC1  # or other supported QPUs
)

# Or using string
config = DynexConfig(
    compute_backend=ComputeBackend.QPU,
    qpu_model="apollo_rc1"  # or other supported QPUs
)

sampler = dynex.DynexSampler(model, config=config)
sampleset = sampler.sample(num_reads=10, annealing_time=500)
```

## Advanced Usage

### BQM Preprocessing

Scale BQM coefficients for QPU compatibility:

```python
import dynex
from dynex import ComputeBackend

# Scale to QPU range
scaled_bqm, scale_factor = dynex.scale_bqm_to_range(bqm, max_abs_coeff=9.0)
model = dynex.BQM(scaled_bqm)

# Sample on QPU
config = DynexConfig(compute_backend=ComputeBackend.QPU, qpu_model=QPUModel.APOLLO_RC1)
sampler = dynex.DynexSampler(model, config=config)
sampleset = sampler.sample(num_reads=10, qpu_max_coeff=9.0)

# Scale energy back
original_energy = sampleset.first.energy / scale_factor
```

### Custom Configuration

Configure SDK behavior through `DynexConfig`:

```python
config = DynexConfig(
    sdk_key="your_sdk_key",
    compute_backend="cpu",
    # Environment parameters (set via config only)
    use_notebook_output=True,      # Dynamic table updates in Jupyter (default: True)
    default_timeout=600.0,          # Max wait time for solutions in seconds (default: 300.0)
    # Job parameters (can override in sampler)
    default_description="My Job",   # Default job description
    preserve_solutions=False,       # Keep solution files after processing (default: False)
)

sampler = dynex.DynexSampler(model, config=config)

# Job parameters can be overridden per sampler
sampler = dynex.DynexSampler(
    model,
    config=config,
    description="Custom Job",        # Override default_description
    preserve_solutions=True,          # Override preserve_solutions
)
```

**Configuration Parameters:**

**Environment Parameters (config only):**
- `use_notebook_output` - Enable dynamic table updates in Jupyter Notebook (default: `True`)
  - `True`: Table updates in-place with `clear_output()` (Jupyter)
  - `False`: Each table printed separately (console/scripts)
- `default_timeout` - Maximum wait time for solutions in seconds (default: `300.0`)

**Job Parameters (config + override):**
- `default_description` - Default job description (default: `"Dynex SDK Job"`)
- `preserve_solutions` - Keep solution files after processing (default: `False`)

### Constrained Quadratic Models (CQM)

```python
from dimod import ConstrainedQuadraticModel, Binary

# Create CQM
cqm = ConstrainedQuadraticModel()
x = [Binary(f'x{i}') for i in range(5)]

# Add objective
cqm.set_objective(sum(x[i] * x[i+1] for i in range(4)))

# Add constraint
cqm.add_constraint(sum(x) == 2)

# Sample
model = dynex.CQM(cqm)
sampler = dynex.DynexSampler(model)
sampleset = sampler.sample(num_reads=10)
```

### Discrete Quadratic Models (DQM)

```python
from dimod import DiscreteQuadraticModel

# Create DQM
dqm = DiscreteQuadraticModel()
dqm.add_variable(3)  # variable with 3 states
dqm.add_variable(2)  # variable with 2 states

# Set interactions
dqm.set_linear(0, [1.0, 2.0, 3.0])
dqm.set_quadratic(0, 1, {(0, 0): 1.0, (1, 1): -1.0})

# Sample
model = dynex.DQM(dqm)
sampler = dynex.DynexSampler(model)
sampleset = sampler.sample(num_reads=10)
```

## Logging & Monitoring

Dynex SDK provides comprehensive logging with platform-specific prefixes and detailed timing information.

## Development

Clone the repo and set up the environment with a single command:

```bash
git clone https://github.com/tapok1999/dynex-sdk
cd dynex-sdk
make install
```

This runs `uv sync --group dev` — creates `.venv` and installs all dependencies from the lockfile.

### Running tests

```bash
make test-unit          # unit tests
make test-integration   # integration tests (needs .env with credentials)
make test               # all tests
```

Or directly via uv:

```bash
uv run pytest tests/unit/ -v
```

### Code quality

```bash
make format   # black + isort
make check    # check without changes
make lint     # flake8
```

### Adding dependencies

```bash
uv add <package>              # runtime dependency
uv add --group dev <package>  # dev-only dependency
uv lock                       # regenerate lockfile after manual edits to pyproject.toml
```

### Building

```bash
make build    # produces dist/dynex-*.whl and dist/dynex-*.tar.gz
```
