Part 4/7:
When measuring a qubit, it collapses to either |0⟩ or |1⟩ based on probability amplitudes. This measurement process is integral to how quantum algorithms derive results. Also critical is the notion of quantum entanglement, where the state of one qubit is intrinsically linked to the state of another, regardless of distance.
Key Quantum Algorithms
Deutsch's Algorithm
Deutsch's algorithm serves as an early example showing the power of quantum computing by determining whether a function is constant or balanced with only one query. This stands in stark contrast to classical approaches requiring multiple queries.
