Quantum Apps / Games

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.

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

Quantum Writing Prompt Generator

This app was made for Gotham Writers’ Workshop. It provides a writing prompt of the form “A <character> who <situation>.” randomly generated by a quantum computer.
