QMem

# QMem

**QMem** is a quantum-inspired memory simulation library written in Rust. It allows bits to exist in a state of superposition—simultaneously 0 and 1—until measured. This unique approach lets you experiment with quantum-like behavior using a simple, intuitive API.

## Features

- **Quantum-Inspired Simulation**: Bits can be in a definite state (0 or 1) or remain in superposition.
- **Simple API**: Easily set, measure, and display the state of your quantum-inspired memory.
- **64-Bit Memory**: Simulate a memory array of 64 bits with efficient, low-level manipulation.
- **Randomized Collapse**: When measured, bits in superposition randomly collapse to 0 or 1.
- **Rust-Powered Performance**: Built with Rust for speed, safety, and concurrency.

## Installation

Add QMem as a dependency in your `Cargo.toml`:

```toml
[dependencies]
qmem = "0.1.1"

Then import it in your Rust project:

use qmem::QMem;

Usage

Here's a simple example demonstrating how to use QMem:

use qmem::QMem;

fn main() {
    // Create a new QMem instance with all bits in superposition.
    let mut q_array = QMem::new();

    // Set bit 0 to a definite value (1).
    q_array.set_bit(0, Some(true));

    // Set bit 1 to a definite value (0).
    q_array.set_bit(1, Some(false));

    // Bit 2 remains in superposition (default state).

    // Measure bits:
    let bit0 = q_array.measure(0); // Always returns true (1).
    let bit1 = q_array.measure(1); // Always returns false (0).
    let bit2 = q_array.measure(2); // Randomly returns true or false.

    println!("Bit 0: {}", bit0);
    println!("Bit 1: {}", bit1);
    println!("Bit 2: {}", bit2);

    // Print the current state of the memory.
    q_array.print();
}

API Reference

QMem::new() -> Self

Creates a new QMem instance with all 64 bits initialized in superposition.

set_bit(&mut self, index: usize, value: Option<bool>)

Sets the bit at the specified index:

• Some(true) sets the bit to 1.
• Some(false) sets the bit to 0.
• None leaves the bit in superposition.

measure(&mut self, index: usize) -> bool

Measures the bit at the given index:

• If the bit is already in a definite state, returns that value.
• If the bit is in superposition, randomly collapses it to 0 or 1 and returns the result.

print(&self)

Prints the current state of the memory, displaying:

• The definite state of each bit (0s and 1s).
• Which bits are still in superposition.

Implementation Details

QMem manages two 64-bit integers internally:

• state: Holds the current collapsed values of the bits.
• superposition: Uses a bitmask to indicate which bits remain in superposition (a 1 means the bit is still in superposition).

The randomness during measurement is handled by the rand crate (version 0.9).
