A TypeScript package for sparse tensor operations on complex numbers in your browser - for quantum computing, quantum information, and interactive visualizations of quantum physics. For more details, see our preprint:

Quantum Tensors are developed by Quantum Flytrap and were supported by the Centre of Quantum Technologies, National University of Singapore. They are a part of the Quantum Game 2 project, are used in BraKetVue quantum state visualizer, and serve as a prototype for numerics for Virtual Lab by Quantum Flytrap, and in an interactive blog post:
- C. Zendejas-Morales, P. Migdał, Quantum logic gates for a single qubit, interactively
Documentation: quantum-flytrap.github.io/quantum-tensors (generated by TypeDoc). Some examples of its usage are demos, tests folders.
We base the philosophy of this package on:
- Sparse operations (both for vectors and matrices)
- Complex numbers
- Tensor structure
- Named tensor dimensions (vide Tensors considered harmful): there is a difference between a 2x2 operator on spin and polarization. It helps with catching errors.
A few insights on contributing, and starting your projects, are in How I Learned to Stop Worrying and Love the Types & Tests: the Zen of Python for TypeScript by Piotr Migdał.
The easiest way is to install from the NPM repository:
npm install quantum-tensors
Or, if you use yarn package manager,
yarn add quantum-tensors
If you want to install a development version, you can get this package directly from this GitHub repository. In this case, the commands are:
npm install Quantum-Flytrap/quantum-tensors#master
Or if you use yarn:
yarn add Quantum-Flytrap/quantum-tensors#master
And then in your project write:
import * as qt from 'quantum-tensors'

- Create TSDoc for each new function, class, and method
- Setup ESLint configured as in this
.eslintrc.js - Try to adhere to Angular-like commit style
