Quantum Without the Physics — What It Can Actually Do

Quantum is three different fields, and most confusion comes from mixing them up. Computing tackles problems where the number of possible combinations explodes — routing, scheduling, materials, portfolios. Sensing measures things classical instruments cannot detect, from underground structures to biological signals. Communication secures the transfer of information through physics rather than mathematics. Forty-five minutes, no formulas, no sales pitch: what each one is used for, what people are building with it, and why encryption is the one area with a deadline already on the calendar.
