The quantum tunneling effect is among the most fascinating and astonishing phenomena in modern physics. At first glance, it challenges the classical laws of mechanics that we intuitively apply to our macroscopic world. However, at the heart of the infinitely small, in the realm of atomic and subatomic particles, this phenomenon plays a fundamental role … Read more
Quantum mechanics profoundly alters our understanding of the world. It describes tiny objects, such as electrons and atoms, with principles that are sometimes counterintuitive, like the superposition of states or entanglement. Yet, despite this fundamental strangeness, solid and defined objects that obey the much more familiar laws of classical physics appear around us in our … Read more
Quantum entanglement remains one of the most fascinating and mysterious phenomena in quantum physics. This ability to establish an immediate and unbreakable link between quantum states of particles, regardless of their distance, upends our classical concepts of reality and causality. This connection surpasses the simple idea of superposition and introduces the notion of non-locality, challenging … Read more
