Entanglement

Quantum mechanics is the science of subatomic particles—the building blocks of matter, including ourselves. It is one of the pillars of the 20th century scientific thinking and one of the most successful quantitative theories of nature.

Quantum mechanics concerns with the principles that describes the interaction of matter and energy in the atomic and subatomic level where the laws of classical Newtonian physics break down completely. Developed during the start of the twentieth century, quantum mechanics is the quintessential tool for calculating and predicting the results of a vast number of experiments and in creating new and advanced technologies based on the insight it provides into the behavior of atomic objects. Much of today’s information technology is possible because of quantum mechanics. It is the underlying principle for many of today’s devices, from lasers, transistors, to charge-coupled devices (CCD), to name a few. “Quantum mechanics was instrumental in predicting antimatter, understanding radioactivity (leading to nuclear power), accounting for the behavior of materials such as semiconductors, explaining superconductivity, and describing interactions such as those between light and matter (leading to the invention of the laser) and of radio waves and nuclei (leading to magnetic resonance imaging)” (Tegmark & Wheeler, 2001, p. 75). And despite of scrutiny of innumerable experiments involving “light, atoms, molecules, and solids, as well as nuclei, electrons, and other subatomic particles”, no violation of quantum mechanics has ever been detected.

As we will see later in this article, this is just the tip of the iceberg.
