Magnetic flux quantum

The magnetic flux quantum, often denoted as \(\Phi_0\), is a fundamental constant in quantum physics that describes the smallest possible unit of magnetic flux that can exist in a superconductor. It is particularly important in the context of superconductivity and quantum mechanics. The magnetic flux quantum is defined as: \[ \Phi_0 = \frac{h}{2e} \] where: - \(h\) is Planck's constant (approximately \(6.
