What Does Quantum Mean? Quantum comes from the Latin meaning how much. It refers to the discrete units of matter and energy that are predicted by and observed in quantum physics The unit of energy is J (Joule) which is also kg m2/s2 (kilogram meter squared per second squared). Energy can be in many forms! Here we look at Potential Energy (PE) and Kinetic Energy (KE) HLG Quantum Boards® are the world's highest efficiency, high intensity horticulture LED light engines.
