<prompt> I-Ternary computer esebenzisa i-fiber optics ingasebenzisa ubumnyama njenge-0 kanye ne-orthogonal polarizations yokukhanya njenge-1 no -1. IBM ibuye ibike kaningi ngezihloko ze-ternary computing emaphepheni ayo, kepha ayihlanganyeli kuyo. I-Josephson junction ihlongozwe njengeseli lememori elilinganisiwe le-ternary, elisebenzisa imisinga ejikelezayo, noma ngokuphambene newashi, noma ngokuphambene newashi.  <response>: amakhompyutha amathathu
