Projects

• Monte Carlo simulation for quantum information: Developed and implemented an algorithm to numerically estimate the information content about entanglement that is provided by the method of entanglement witnesses in quantum information.
• Python implementation of a quantum contextuality algorithm: Produced a python implementation of an algorithm from quantum contextuality that is aproximately 60x faster and simpler to use than the its original Matlab implementation.
• Deep learning building blocks and autograd in NumPy: A NumPy implementation of many important machine learning elements including Adam and SGD optimizers, convolutional and linear layers, dropout, batch and layer normalization, RNNs, LSTMs and transformers. Done for educational purposes.
• Web development elements: Simple implementations of toy projects such as a blog, a todo list and pure css tictactoe game.
