What is Quantum Physics?
Quantum physics is the branch of science that deals with the behavior of matter and energy on the atomic and subatomic levels. Unlike classical physics, which excels in explaining macroscopic phenomena, quantum physics introduces concepts that defy intuitive understanding, such as superposition, entanglement, and quantum tunneling. These phenomena form the basis for technologies that could drastically outperform current classical systems.
Advancements in Quantum Computing
Quantum computing represents one of the most fascinating applications of quantum physics. Unlike classical computers that rely on binary bits (0s and 1s), quantum computers use quantum bits, or qubits, that can exist in multiple states at once—a property known as superposition. This enables quantum computers to process complex algorithms much faster than traditional computers.
This computational prowess is already being harnessed to solve problems in cryptography, materials science, and pharmaceuticals. Companies like IBM, Google, and Rigetti are pioneering quantum hardware advancements, making quantum computing increasingly accessible.
