kvanttibitilla
A kvanttibitti, often referred to as a qubit, is the fundamental unit of quantum information. Unlike a classical bit, which can represent either a 0 or a 1, a qubit can exist in a superposition of both states simultaneously. This superposition is represented mathematically as a linear combination of the basis states |0⟩ and |1⟩.
The state of a qubit is often described using the Bloch sphere, a geometrical representation where the
Qubits can be entangled with each other, a phenomenon where their fates become correlated regardless of the
The practical realization of qubits is a significant challenge in quantum computing research. Various physical systems
