By the 1960s – 1970s quantum electrochemistry was developed by Revaz Dogonadze and his pupils.

By 1930, quantum mechanics had been further unified and formalized by the work of Paul Dirac and John von Neumann, with a greater emphasis placed on measurement in quantum mechanics, the statistical nature of our knowledge of reality, and philosophical speculation about the role of the observer.

By removing the need to load the particle with the properties of space and time, a fully deterministic, local and causal description of quantum phenomena is possible by use of a simple dynamical operator on a Universal Invariant Set.

By using quantum superpositions or quantum entanglement and transmitting information in quantum states, a communication system can be implemented which detects eavesdropping.

By the many-worlds interpretation of quantum physics, the quantum randomization spawns ( where N is the number of random bits ) universes and one of these will be such that this single shuffle had produced the list in sorted order.

By 1928 Dirac deduced his equation from the first successful unified combination of special relativity and quantum mechanics to the electron-the Dirac equation.

By contrast, if the detector sees photons emitted directly from a ( hot ) glowing gas, then the detector often sees photons emitted in a narrow frequency range by quantum emission processes in atoms in the gas, and this results in an emission line.

By the Pauli exclusion principle, no quantum state can be occupied by more than one fermion with an identical set of quantum numbers.

By using these phosphorescent materials, both singlet and triplet excitons will be able to decay radiatively, hence improving the internal quantum efficiency of the device compared to a standard PLED where only the singlet states will contribute to emission of light.

By doing so, it is possible to handle certain systems, such as aspects of quantum mechanics, that would otherwise be even more complicated.

By Jaynes ' reasoning, if the particles are experimentally indistinguishable for whatever reason, Gibbs paradox is resolved, and quantum mechanics only provides an assurance that in the quantum realm, this indistinguishability will be true as a matter of principle, rather than being due to an insufficiently refined experimental capability.

By the structure of quantum operations, this description is mathematically equivalent to that offered by relative state interpretation where the original system is regarded as a subsystem of a larger system and the state of the original system is given by the partial trace of the state of the larger system.

By analytic continuation of the correlation functions of a quantum field theory, the time coordinate may become imaginary, and then boosts become rotations.

By contrast, if the detector sees photons emitted directly from a glowing gas, then the detector often sees photons emitted in a narrow frequency range by quantum emission processes in atoms in the hot gas, resulting in an emission line.

By taking quantum physics into account, the gravastar hypothesis attempts to resolve contradictions caused by conventional black hole theories.

By introducing the quantum defect d as an empirical parameter, the energy levels of a generic atom were well approximated by the formula, in the sense that one could reproduce fairly well the observed transitions levels observed in the X-ray region ( for example, see the empirical discussion and derivation in Moseley's law ).

By applying small voltages to the leads, the flow of electrons through the quantum dot can be controlled and thereby precise measurements of the spin and other properties therein can be made.

By giving the atom additional energy ( for example, by the absorption of a photon of an appropriate energy ), the electron is able to move into an excited state ( one with one or more quantum numbers greater than the minimum possible ).
