Quantum materials: A new state of matter with chiral properties

An international research group has discovered a new state of matter characterized by the existence of a quantum phenomenon called chiral current. These currents are generated on an atomic scale by a cooperative movement ...

Research reveals quantum entanglement among quarks

Collisions of high energy particles produce "jets" of quarks, anti-quarks, or gluons. Due to the phenomenon called confinement, scientists cannot directly detect quarks. Instead, the quarks from these collisions fragment ...

Shaping the dawn of the quantum age

Electrons that spin to the right and the left at the same time. Particles that change their states together, even though they are separated by enormous distances. Intriguing phenomena like these are completely commonplace ...

Protons reveal universal phenomenon of maximal entanglement

When a high-energy photon strikes a proton, secondary particles diverge in a way that indicates that the inside of the proton is maximally entangled. An international team of physicists with the participation of the Institute ...

New quantum optics technique sheds light on polariton interactions

An international collaboration, led by Macquarie University scientists, has introduced a new quantum optics technique that can provide unprecedented access to the fundamental properties of light-matter interactions in semiconductors.

Quantum mechanics

Quantum mechanics is a set of principles underlying the most fundamental known description of all physical systems at the submicroscopic scale (at the atomic level). Notable among these principles are simultaneous wave-like and particle-like behavior of matter and radiation ("Wave–particle duality"), and the prediction of probabilities in situations where classical physics predicts certainties. Classical physics can be derived as a good approximation to quantum physics, typically in circumstances with large numbers of particles. Thus quantum phenomena are particularly relevant in systems whose dimensions are close to the atomic scale, such as molecules, atoms, electrons, protons and other subatomic particles. Exceptions exist for certain systems which exhibit quantum mechanical effects on macroscopic scale; superfluidity is one well-known example. Quantum theory provides accurate descriptions for many previously unexplained phenomena such as black body radiation and stable electron orbits. It has also given insight into the workings of many different biological systems, including smell receptors and protein structures.
