quantum mechanics (2061 uses)
The configuration of these electrons follows from the principles of quantum mechanics.
quantum field (776 uses)
A unified interpretation of antiparticles is now available in quantum field theory, which solves both these problems.
quantum mechanical (450 uses)
Atomic orbitals may be defined more precisely in formal quantum mechanical language.
quantum theory (374 uses)
Bootstrapping is using very general consistency criteria to determine the form of a quantum theory from some assumptions on the spectrum of particles.
quantum gravity (367 uses)
Sakharov also proposed the idea of induced gravity as an alternative theory of quantum gravity.
quantum number (293 uses)
Each orbital is defined by a different set of quantum numbers ( n, l, and m ), and contains a maximum of two electrons each with their own spin quantum number.
quantum physics (274 uses)
A 2008 quantum physics experiment performed in Geneva, Switzerland has determined that in any hypothetical nonlocal hidden-variables theory the speed of the quantum non-local connection would have to be at least 10, 000 times the speed of light.
quantum state (251 uses)
In quantum field theory, this process is allowed only as an intermediate quantum state for times short enough that the violation of energy conservation can be accommodated by the uncertainty principle.
quantum numbers (202 uses)
Atomic orbitals are typically categorized by n, l, and m quantum numbers, which correspond to the electron's energy, angular momentum, and an angular momentum vector component, respectively.
quantum electrodynamics (193 uses)
When this field is instead studied using the QED vacuum of quantum electrodynamics, it is seen that the plates do affect the virtual photons which constitute the field, and generate a net force — either an attraction or a repulsion depending on the specific arrangement of the two plates.
quantum states (177 uses)
In atomic physics, the atomic spectral lines correspond to transitions ( quantum leaps ) between quantum states of an atom.
quantum chemistry (166 uses)
( quantum chemistry ) and spectroscopy.
quantum computer (151 uses)
In computational complexity theory, BQP ( bounded error quantum polynomial time ) is the class of decision problems solvable by a quantum computer in polynomial time, with an error probability of at most 1 / 3 for all instances.
quantum information (139 uses)
* Bell state, in quantum information science
quantum dots (135 uses)
Several condensed matter systems are being studied with potential applications to quantum computation, including experimental systems like quantum dots, SQUIDs, and theoretical models like the toric code and the quantum dimer model.
quantum system (125 uses)
In quantum computing, a quantum bit or qubit is a quantum system that can exist in superposition of two bit values, " true " and " false ".
quantum computing (107 uses)
In quantum computing, a quantum bit or qubit is a quantum system that can exist in superposition of two bit values, " true " and " false ".
quantum chromodynamics (104 uses)
In Skyrme's model, reproduced in the large N or string approximation to quantum chromodynamics ( QCD ), the proton and neutron are fermionic topological solitons of the pion field.
quantum effects (84 uses)
Scientists have achieved temperatures very close to absolute zero, where matter exhibits quantum effects such as superconductivity and superfluidity.
quantum of (79 uses)
When Alaska Natives enrolled in their regional corporations under the terms of the Alaska Native Claims Settlement Act of 1971 ( ANCSA ), the Aleut Corporation attracted only about 2, 000 enrolees who could prove a blood quantum of 1 / 4 or more Alaska Native ( including Aleut ).
quantum Hall (73 uses)
The standard ampere is most accurately realized using a watt balance, but is in practice maintained via Ohm's Law from the units of electromotive force and resistance, the volt and the ohm, since the latter two can be tied to physical phenomena that are relatively easy to reproduce, the Josephson junction and the quantum Hall effect, respectively.
quantum dot (70 uses)
In fact, a protein or other component can be " labelled " with an extrinsic fluorophore, a fluorescent dye that can be a small molecule, protein, or quantum dot, finding a large use in many biological applications.
quantum entanglement (68 uses)
Recent papers by Guerreshi, G., Cia, J., Popescu, S. and Briegel, H. could falsify proposals such those of Hameroff which rely on quantum entanglement in protein.
quantum computation (63 uses)
Several condensed matter systems are being studied with potential applications to quantum computation, including experimental systems like quantum dots, SQUIDs, and theoretical models like the toric code and the quantum dimer model.
quantum efficiency (59 uses)
* Optics, the electromagnetic impedance of a medium, or the quantum efficiency of detectors.
