description Overview

qubit

The basic unit of quantum information, a qubit is a system with two distinguishable basis states conventionally labeled 0 and 1. Unlike a classical bit, its state can be a superposition of those basis states, described by complex amplitudes. These amplitudes determine measurement probabilities, while their relative phase matters when quantum operations cause different contributions to interfere....

qudit

A qudit is a generalization of the qubit, representing a quantum system with *d* possible states—where *d* is an integer greater than or equal to two—and enabling richer computational possibilities than qubits alone.
