Quantum Kittens (Beta)
From marbles that are red and blue at the same time to feathers that spontaneously appear and disappear, the cat world is a little funkier than ours. This illustrated dive into their world aims to explain the concepts of quantum physics, and how these properties open doors to powerful computing.

Quantum Apps / Games
Quantum Grove: A Lofi Ambience
Welcome to Kvantti Kunj, where playful critters scamper about lush terrain, and a qubit controls what you see…
Quantum Grove is an interactive art piece playable in the browser that functions as a lofi ambience for study, work, and relaxation.

Doctor Cat
Game link: https://quantum-kittens.itch.io/doctor-cat
Doctor Who meets quantum superposition in this minimal Bitsy game. Oh, and the Doctor is a cat.
Story
You just saved a distant planet from giant sentient balls of yarn. It’s time to return home to present-day Earth for a well-deserved nap… but the Tardis has been giving trouble lately. Every time you input destination coordinates, the Tardis puts multiple potential destinations in a quantum superposition, so you don’t always end up where you want to go!
Version 1.0
There’s just one storyline for now, but I hope to add a few branches down the line.
Game Engine
Made with Bitsy

The Photonic Trail
A web-based educational game published on QPlayLearn.
The Photonic Trail is an immersive quantum optics single-player fantasy game that allows anyone from beginners to seasoned pros inculcate quantum optics concepts through game play. It is a treasure hunt with six missions that span the basics of quantum optics. I was responsible for: the concept and stories, art direction, the trailer, building the UI, and part of the physics.
Each mission is a locked webpage. If you’d like to read through the stories, I’ve written the password in white-simply highlight them!

The D&D μStarter Kit
This is a helper tool for players of Dungeons and Dragons. Roll dice, generate a character with an ad-libbed one-line backstory, or play a complete ad-libbed D&D scene! The D&D μStarter Kit makes use of quantum computing for randomness and ad-libs, alongside user inputs. This generator is based on the D&D 5E Player’s Handbook.
Functionalities:
- A character generator that provides a race, class, name, and a one-line ad-libbed backstory
- A dice roller to determine ability scores or to use during gameplay
- An ad-libbed D&D scene
