Executive Summary

As quantum computing emerges as a transformative technology, understanding its fundamental principles becomes crucial for engineers and researchers. This project demonstrates how Field-Programmable Gate Arrays (FPGAs) can serve as powerful platforms for quantum computing education and simulation, making complex quantum concepts accessible through hands-on implementation.

We successfully developed and deployed a quantum coin flip simulation on an Intel MAX10 FLK FPGA development board, creating an interactive demonstration that showcases key quantum mechanical principles including superposition, quantum measurement, and true randomness generation.

Quantum Computing Basics: Understanding the Fundamentals

What is Quantum Computing?

Quantum computing harnesses quantum mechanical phenomena to process information in ways impossible for classical computers. While classical computers use bits (0 or 1), quantum computers use quantum bits (qubits) that can exist in superposition – simultaneously being both 0 and 1 until measured.

Core Quantum Principles

1. Superposition
A qubit can exist in a combination of |0⟩ and |1⟩ states simultaneously. This is like a coin spinning in the air – it’s both heads and tails until it lands. Mathematically represented as: |ψ⟩ = α|0⟩ + β|1⟩

2. Quantum Measurement

When we measure a qubit in superposition, it “collapses” to either |0⟩ or |1⟩ with probabilities determined by the quantum amplitudes. This collapse is genuinely random – even Einstein called it “spooky action.”

3. Quantum Gates
These are operations that manipulate qubit states. The most important is the Hadamard gate, which creates equal superposition:

                                   H = (1/√2) × [1  1 ]
                                              [1 -1]

4. Quantum Entanglement
Qubits can become “entangled,” creating mysterious correlations where measuring one instantly affects another, regardless of distance.
