A library for simulating quantum computations in Swift.

The library is split into two modules:

- `Quantum`, the main library

- `QuantumBuilder`, an ergonomic (result builder-based) DSL for expressing quantum compuations

`QuantumBuilder` re-exports `Quantum`, so you only have to import one of the two, depending on what you need.

## Example

A simple coin flip that outputs `true` or `false` with equal probability can be implemented as follows:

```swift

import QuantumBuilder

let program = QuantumProgram {

    Hadamard()

    Measure()

}

for _ in 0..<8 {

    print(try program.measuredState(for: [false]))

}

```

To try this example, run

```sh

swift run CoinFlip

```

An example output would be:

```

[true]

[true]

[true]

[false]

[false]

[true]

[false]

[true]

```
