QCi, it appears, traffics in photonic quantum chips – minuscule constellations of light, beamed through silicon and glass. The conceit, rather elegant, is that these chips might circumvent the cryogenic demands of more conventional quantum architectures. Room temperature, you see, is a desirable condition, suggesting a certain domesticity, a lessening of the chillingly abstract. Yet the reality, as is so often the case, proves more recalcitrant. These chips, while theoretically cheaper and more scalable, currently exhibit a disconcerting tendency toward error, requiring cumbersome optical appendages and proving, ironically, costly to manufacture in modest quantities. A paradox, wouldn’t you agree?
