Q1Synth

A built version of this app is hosted at https://iccmr-q1synth-proto.cephasteom.co.uk/.

Rotate the qubit to interpolate between different synthesis parameters on each axis. Measure the qubit for it to collapse to either 1 or 0. At the time of writing, this app is hosted here.

Prerequisites

• Install Node
• Install Node Version Manager (NVM)
• Install Yarn

Local Setup

• clone this repo and navigate to directory root
• nvm use - use node version manager to switch to correct node version
• yarn or npm i- install node packages
• yarn start or npm run start - spin up the app

Measurement

By default, qubit measurement is simply handled by a local, weighted coin toss function. To connect to a QASM simulator or a real quantum computer, you will need to set up a local python server running a socket/qasm script. See ICCMR's socket-qasm implementation.

Once socket-qasm is up and running, include the query parameter ?qasm in the app url. For example, locally -> http://localhost:3000/?qasm=true. Successful connection should print an alert in your browser.

Midi Input

A midi input device can be chosen from the dropdown in the config panel. QuSynth listens for control change messages on any midi channel of the selected device. A Max patch is included in this repo to map controls to a midi controller.

Midi Mapping

Control change messages are mapped to the controls, as laid out in the file src/midi/midiMap.ts.

Ensemble Mode

• Build local version of the app (see above)
• yarn build or npm run build to bundle assets
• yarn start-ensemble or npm run start-ensemble to serve bundle and send osc
• Open http://localhost:3000?ensemble=true&id=someID to run app in ensemble mode.

This transmits the x, y, and z position of the qubit over osc. See /src/osc/socket-to-udp.js for details of the osc port.

Further Development

This project was bootstrapped with Create React App, using the Redux and Redux Toolkit template.

Available Scripts

In the project directory, you can run:

yarn start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

yarn test

Launches the test runner in the advanced watch mode.
See the section about running tests for more information.

yarn build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

yarn eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
