Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical physics cannot.
James K. Freericks (born 1963) is an American physicist and endowed chair at Georgetown University. He has worked in fields of condensed matter physics, mathematical physics, atomic physics, nonequilibrium physics, quantum computation, and quantum mechanics pedagogy.
10 of the most influential figures in the history of quantum mechanics. Left to right: Max Planck, Albert Einstein, Niels Bohr, Louis de Broglie, Max Born, Paul Dirac, Werner Heisenberg, Wolfgang Pauli, Erwin Schrödinger, Richard Feynman. The history of quantum mechanics is a fundamental part of the history of modern physics.
The application of quantum mechanics to chemistry is known as quantum chemistry. Quantum mechanics can also provide quantitative insight into ionic and covalent bonding processes by explicitly showing which molecules are energetically favorable to which others and the magnitudes of the energies involved.

In the classical world, information can be copied and deleted perfectly. In the quantum world, however, the conservation of quantum information should mean that information cannot be created nor destroyed. This concept stems from two fundamental theorems of quantum mechanics: the no-cloning theorem and the no-deleting theorem. But the no-hiding ...
Quantum mechanics is the study of matter and its interactions with energy on the scale of atomic and subatomic particles.By contrast, classical physics explains matter and energy only on a scale familiar to human experience, including the behavior of astronomical bodies such as the moon.
The quantum computing revolution is changing technology as we know it. Quantum computers leverage the principles of quantum mechanics to perform calculations far beyond the capabilities of ...
He pioneered categorical quantum mechanics (entry 18M40 in Mathematics Subject Classification 2020), Quantum Picturalism, [4] ZX-calculus, DisCoCat model for natural language, [5] and quantum natural language processing (QNLP). He is a founder of the Quantum Physics and Logic community and conference series, and of the journal Compositionality.
