![]() while particle physics discuss subatomic particles such as elementary particles. The key difference between quantum physics and particle physics is that quantum physics deals with the smallest scales of energy levels of atoms whereas particle physics deals with particles that constitute matter and radiation.įurthermore, quantum physics discuss energy, momentum, angular momentum, etc. Quantum physics is also called quantum mechanics it is a major branch of physics as well as chemistry. What is the Difference Between Quantum Physics and Particle Physics? The standard model presents the dynamics of the subatomic particles. They are useful concepts in studying the particles. Moreover, particle physics deal with the dynamics of these particles such as the wave-particle duality. that form from radioactive processes and scattering processes. Subatomic particles include protons, neutrons, electrons, etc. The term particle may refer to different objects, but in particle physics, we usually talk about smallest detectable particles subatomic particles. Particle physics is a branch of physics in which we study the nature of particles that constitute matter and radiation. The important fields where we need to apply quantum theory include quantum chemistry, quantum optics, quantum computing, superconducting magnets, light-emitting diodes, laser, transistors, semiconductors such as the microprocessor, medical and research imaging such as magnetic resonance imaging, and electron microscopy. ![]() However, the early quantum mechanics came to fame in 1920 with the work of Erwin Schrödinger, Werner Heisenberg, Max Born and others.įigure 01: Max Planck – the Father of Quantum Theory In history, the concept of quantum mechanics arose with the findings and theories of Max Planck (black body radiation) and Einstein (photoelectric effect). According to quantum physics, energy and momentum are quantized, objects show wave-particle duality, and there are limits to the precision with which quantities can be measured. Another common name for this term is quantum mechanics because it describes the mechanical properties of atoms. Quantum physics is a branch of physics in which we study the nature of small scale energy levels of atoms. Side by Side Comparison – Quantum Physics vs Particle Physics in Tabular Form In fact, we call particle physics “high energy physics” because it explains the behaviour of particles at high energies. Nevertheless, quantum physics is often applied in particle physics. ![]() However, they are different from each other. Quantum physics and particle physics are two major branches of physics. The key difference between quantum physics and particle physics is that quantum physics deals with the smallest scales of energy levels of atoms whereas particle physics deals with particles that constitute matter and radiation.
