Introduction



We experimented with IBM's Quantum Composer to create a quantum circuit composed of two qubits in superposition. However, because today's quantum computers are not perfect, we soon realized that while superposition allows two qubits to be reliant on each other, random noise disrupts the perfect symmetry. This leads us to the question: What happens to a complex system when one part falls out of order?




(A) Initial Prototype



Design process


With our quantum gate-configuration, we found that the qubits exist mainly in 2 states: 48.5% of them exist as state (0, 0), 45% of them exist as state (1,1). Some qubits also existed as noise, with states (0,1) or (1, 0). 


State (0, 0) is represented by our first medium- the visual projections.

State (1, 1) is represnted by our second medium, sound. 


By overlapping the two mediums, we show the "in between" states of the qubits- the uncertainty of their states, and prove that one cannot know their states until one measures them.




Projections representing state (0,0)




Each projection (created in p5.js) represents one qubit in state 0

If both qubits are in state 0, the projection is a symmetrical pattern because the qubits are entangled.

Every now and then, the pattern on either projection glitches.

This disruption of the perfect symmetry is caused by noise- when the qubits are in state [0,1] or [1,0]

noise that occurs



Sound representing state (1,1)


Each speaker represents one qubit in state 1.

The Quantum Music Composer enabled us to create a bass audio with state [1,1]. 

The bass audio is played through the two speakers, which create sound saves of different amplitudes and frequencies.

This sound energy is then converted into kinetic energy in the water, creating interesting waveforms in the petri dishes.

Integrating sound + projections



Due to the water movement caused by the oscillation from the speakers, the p5.js projection in each petri dish is warped according to the [1,1] state of the quantum circuit.

As a result, the final projection on the ceiling is influenced by the [0,0], [1,1] and noise states.

Design process



As we could not play music out loud in the exhibition space, we had to resort to making the user wear headphones to listen to the changes in frequency/ oscillations. 

However, because we could not play music out loud, we had to find another way to make the water in the petri dish vibrate so that the projected image in the petri dish can be warped as well.

At the same time, we had to figure out a way to allow the user to hear the changes in frequency/ oscillations. 

We came up with this configuration:
