" summary

Qubits hold superpositions so multiple input states evolve together and algorithms steer their phases to make correct answers constructively interfere while wrong ones destructively interfere. Shor’s algorithm can factor large integers exponentially faster than classical methods but yields probabilistic results that may need repeated runs; the Deutsch algorithm can be deterministic. Experimental work entangles photon pairs, sends one to a satellite and one to ground, and demonstrates quantum teleportation of key information. That breaks current RSA-style encryption but enables quantum key distribution that detects eavesdropping.
