A rather simple example to simulate quantum functionality as a proof of concept. Rather slow due to overhead introduced by the simulator. For comparison, the whole function could be replaced with a single line in javascript.
It is using quantastica quantum-circuit javascript library.
This would be the function performing calculation and returning Uint8 value:
// Reusable single qubit circle which determines
// the polarity of floating-point inputValue and
// returns Uint8 value from range [0, 255]
function run_quantum_circuit( inputValue = 0 ) {
// Map the range [-1, 1] to theta for the U3 gate
// Math.acos will provide radian value from range [0, PI]
const theta = Math.acos( inputValue ).toString();
if (circuit === undefined) {
circuit = new QuantumCircuit();
circuit.appendGate( 'u3', 0, { 'params': { 'theta': theta, 'phi': '0', 'lambda': '0' } } );
} else {
circuit.resetQubit( 0, 0 );
circuit.resetState();
circuit.gates[ 0 ][ 0 ].options.params.theta = theta;
}
circuit.run();
const probabilities = circuit.probabilities();
if (probabilities[ 0 ] === 0.5) {
//console.log(`The input ${inputValue} is zero.`);
return 0;
} else if (probabilities[ 0 ] < 0.5) {
//console.log(`The input ${inputValue} is positive.`);
return ( inputValue * uhi );
} else {
//console.log(`The input ${inputValue} is negative.`);
return ( inputValue * ulo );
}
}
Constants ulo and uhi are declared on the top of the html file as -255 and 255.
You can try this with the attached SingleQubit GLTF Standalone Viewer and any standard texture which you can set as a background once you load some GLTF / GLB model (use the BGND button to load texture locally).
Texture can be JPG or PNG or even EXR and HDR just make sure to use smaller sizes like 128x128 which can take 30+ seconds to process (600x600 took around 10 minutes so be mindful). Attached is an example EXR texture which represents a purple rounded button.
You can also try calling this function by adding some code inside the document_ready() function, like create an array [ 0.0, -0.5, 0.125, -0.8, 0.2 ] and then iterate and call the function for each array value - maybe uncomment the logging inside the function itself so you can see messages.
Try to keep the console open just to see if the message about running the quantum circuit gets logged. This should be true for Float32Array and Uint16Array image data.
If you think that your computer can handle some larger texture then give it a try but make sure that the console shows the message.
Maybe use the circuit keyword to search through the code to see all spots where this is used.

As a disclaimer, this overall approach might be wrong so don’t hesitate to change it.
, I need superconductors with helium cooling
