Quantum physics is difficult and explaining it even more so. Researchers have now tried to solve one of the biggest puzzles in quantum physics: How to measure the quantum system without changing it?
Read moreAccording to quantum physics, energy can be 'borrowed' — at least for some time. Energies lower than zero are possible, much like a bank account that can be overdrawn. There are, however, certain restrictions to that. Scientists have now shown that these restrictions are very fundamental properties of our universe and must be true for various possible quantum theories.
Read moreThe quantum superposition principle has been tested on a scale as never before in a new study. Hot, complex molecules composed of nearly two thousand atoms were brought into a quantum superposition and made to interfere. By confirming this phenomenon — 'the heart of quantum mechanics', in Richard Feynman's words — on a new mass scale, improved constraints on alternative theories to quantum mechanics have been placed.

Read moreAccording to Einstein, light consists of particles (photons) that transfer only quantized energy to the electron of the atom. If the photon's energy is sufficient, it knocks the electrons out of the atom. But what happens to the photon's momentum in this process? Physicists are now able to answer this question. To do so, they developed and constructed and new spectrometer with previously unattainable resolution.
Read morePhysicists have created a quantum material that can travel through a previously unexplored region marked by strange electronic properties. The journey is by an alloy of cerium palladium and aluminum.
Read moreIn 2 breakthroughs in the realm of photonics, researchers are reporting the successful demonstration of an LED (light-emitting diode) based on half-light half-matter quasiparticles in atomically thin materials. This is also the first successful test of an electrically driven light emitter using atomically thin semiconductors embedded in a light trapping structure (optical cavity).
