Quantum Physics: What Is Really Real?
Ever since they invented quantum theory in the early 1900s, explains Maroney, who is himself a physicist at the University of Oxford, UK, they have been talking about how strange it is — how it allows...
A Different Picture Of Quantum Surrealism
With its ideas of particles zipping in and out of existence, quantum mechanics is probably the kookiest-sounding theory in science. And our understanding of it is little helped by the mysterious “pro...
A New ‘Einstein’ Equation Suggests Wormholes Hold Key To Quantum Gravity
A new Einsteinian equation, ER=EPR, may be the clue physicists need to merge quantum mechanics with general relativity.
Quantum Teleportation? Producing Spin-Entangled Electrons
Researchers have successfully produced pairs of spin-entangled electrons and demonstrated that they remain entangled even when they are separated from one another on a chip. This research could contri...

Absorption (optics)
In physics, absorption of electromagnetic radiation is the way in which the energy of a photon is taken up by matter, typically the electrons of an atom. Thus, the electromagnetic energy is transforme...
Photoelectric effect
The photoelectric effect is the observation that many metals emit electrons when light shines upon them. Electrons emitted in this manner can be called photoelectrons.According to classical electromag...
Optical pumping
Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction, to pump ...
Population inversion
In science, specifically statistical mechanics, a population inversion occurs when a system (such as a group of atoms or molecules) exists in a state with more members in an excited state than in lowe...
