Simulating Quantum Entanglement

We simulated entangled quantum states and measured what makes them special, built the standard quantum gates from scratch, and showed a quantum circuit matching a task with 384 times fewer parameters than a classical network.

The problem

Understanding where quantum methods beat classical ones means building and measuring quantum systems, not just reading about them, from distinguishing entangled from unentangled states to benchmarking error-correction decoders.

Solution & architecture

Simulated entangled states (Bell states), measuring entanglement entropy to tell them apart from unentangled ones, and built standard gates from first principles. Benchmarked a surface-code error-correction decoder across 2 code distances and 4 noise levels, and compared a variational quantum circuit against a classical neural network.
