Quantum computing, a field of scientific exploration, is based on the quantum mechanical principle of superposition, which allows particles to exist in multiple states simultaneously. This principle, along with entanglement, a quantum phenomenon that enables particles to be instantaneously connected, provides quantum computers with computational power beyond the reach of classical computers. The development of quantum computing, rooted in the early 20th century, is a testament to intellectual daring, as scientists grappled with concepts that defied logic but were supported by experimental evidence.
