Quantum Amplitude Encoding
IntermediateQuantum Amplitude Encoding is a method for representing a normalized vector of classical data by mapping its values onto the probability amplitudes of a quantum state.
In Plain English
Imagine an audio waveform represented by a series of volume levels. Instead of storing this long list, amplitude encoding maps the entire series into a single quantum state. Each volume level corresponds to the amplitude of a specific basis state in a superposition, making the quantum state a compact representation of the entire waveform.
