The Variational Quantum Eigensolver, Implemented with IBM’s Qiskit

One of the most promising applications of quantum computing in quantum chemistry — If you dabbled in quantum algorithms, you’ve probably heard of the term ‘variational algorithms’ being thrown around a lot. Well, here’s why. The long story short version is that our quantum hardware isn’t nearly as good as it should be (ie, lots of noise, decoherence…) and so, the algorithms that…

Graph Theory 101

A fun introduction to graph theory — what is it and why is it relevant to us today? — A brief origin story One of the most famous cities in mathematics is the medieval German city of Königsberg, which lay on both sides of the Pregel river. In the center of the river, there lay 2 islands that were connected to each other and the river banks by 7 bridges. Something like this: …

Rethinking Gradient Descent with Quantum Natural Gradient

A fun introduction to gradient descent optimization for the variational quantum eigensolver algorithm! — Table of contents: This post has 4 sections, so feel free to skip around if you already know some parts and want to save some time (warning: it’ll take a while to get into the quantum part): Linear regression: building the intuition behind gradient descent Gradient descent in a nutshell…

Keys to Building a High Impact Startup

Reflection and key takeaways from attending a Creative Destruction Lab session — The speed at which emerging tech is progressing is literally exponential. And humans tend to think linearly. So, we don’t really understand the concept of ‘exponential growth’. We are living in a world that is likely unfathomable to someone who lived in the same world 20 years ago. These areas…

The Future of Anti-CRISPR

Putting a stop break on CRISPR-Cas 9 and moderating its function: precision control 101 — Imagine driving a car without a brake, at 150 km an hour. And then suddenly, you hit a bump. Game over. Literally. Similar to a car, CRISPR (which stands for clustered regularly interspaced short palindromic repeats), associated with a protein such as Cas9, is a pair a genetic ‘molecular scissors’…

Grover’s Search Algorithm Using IBM’s Qiskit

Solving the unstructured search problem, the quantum way — Devised by Lov Grover in 1996, Grover’s Algorithm provides an incredible speedup from its classical counterpart. It’s a searching algorithm that allows us to find a certain element in its respective list in O(√N) time, rather than O(N) time and thus, the quadratic speedup. N is the size of the…
