What is a quantum bit (qubit)?

Quantum bits, also known as qubits, are the basic unit of data in quantum computing. Like binary bits in classical computers, they can store information, but they behave very differently because quantum mechanics.

Quantum computer usually use subatomic particles, such as photons (packets of light) or electrons, as qubits. In qubits, properties such as charge, photonic polarization or spin represent 1s and 0s in binary computation. However, qubits are also subject to a phenomenon known as superposition And windingbecause of its quantum nature, this is where things start to get weird.
