Quantum mechanics notes for bsc. Quantum mechanics is the field of physics that explains how extremely small objects simultaneously have the characteristics of both particles (tiny pieces of matter) and waves (a disturbance or variation that transfers energy). Mar 30, 2025 · Quantum mechanics, or quantum physics, is one of the most profound and enigmatic fields in science. Quantum computers use quantum bits or qubits instead of binary bits. Quantum physics is the study of matter and energy at the most fundamental level. Classical physics can describe many aspects of nature at an ordinary (macroscopic and (optical) microscopic) scale, but is not sufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Light, for example, appearing in some respects as a continuous electromagnetic wave, on the submicroscopic level is emitted and absorbed in discrete amounts, or quanta. Quantum mechanics can describe many systems that classical physics cannot. Quantum science aims to better understand the world around us and apply quantum theories to real-world technology solutions. The fundamental notion that a property can be "quantized" is referred to as "the hypothesis of quantization ".
