Short answer guidance
21. Bit versus qubit
A bit is classical and has value 0 or 1. A qubit is quantum and can be in a state that combines possibilities before measurement.
22. Designers and quantum physics
Good examples include LEDs, lasers, solar panels, smartphone displays, sensors, fibre optics, fluorescent materials, reflective coatings, and some smart materials.
23. Superposition as a design theme
A good answer might describe a chair, light, textile, or room that appears to hold more than one possible state, such as a lamp that shifts between colour states or a layered object with ambiguous form.
24. Measurement as interaction
A good answer should mention that the viewer’s action could select or change the artwork. For example, a wall of lights could change pattern when someone approaches or touches it.
25. Interference as pattern
A good answer might mention overlapping waves, moire patterns, layered transparent materials, perforated panels, acoustic forms, light and shadow patterns, or ripple-like structures.
26. Entanglement as relationship
A good answer might describe two lamps, chairs, textiles, or rooms that respond together, so that each object feels incomplete without the other.
27. Quantum materials
Quantum computers may help simulate matter at the quantum level, which could support discovery of new materials for batteries, lighting, coatings, pigments, solar cells, or smart textiles.
28. Quantum computing and design judgement
Design involves human needs, aesthetics, culture, emotion, ethics, accessibility, sustainability, and context. Quantum computing may become a tool, but it does not replace design judgement.
29. Quantum-inspired classroom project
Good answers might include a random tile generator, an interactive light installation, an entangled-lamp prototype, a moire wall panel, a probability-based textile, or a superposition-inspired furniture concept.
30. Myth checking
Quantum computers do not simply reveal all possible answers. Measurement gives limited information, and useful quantum algorithms must be carefully designed. Design also requires human judgement, not just search.
