quantum

n 1: a discrete amount of something that is analogous to the
quantities in quantum theory
2: (physics) the smallest discrete quantity of some physical
property that a system can possess (according to quantum
theory) |
quantum
(foldoc) | time slice
quantum
time quantum
(Or "time quantum", "quantum") The period
of time for which a process is allowed to run uninterrupted in
a pre-emptive multitasking operating system.
The scheduler is run once every time slice to choose the
next process to run. If the time slice is too short then the
scheduler will consume too much processing time but if it is
too long then processes may not be able to respond to external
events quickly enough.

quantum bogodynamics
(foldoc) | quantum bogodynamics
/kwon'tm boh"goh-di:-nam"iks/ A theory that characterises the
universe in terms of bogon sources (such as politicians,
used-car salesmen, TV evangelists, and suits in general),
bogon sinks (such as taxpayers and computers), and bogosity
potential fields. Bogon absorption causes human beings to
behave mindlessly and machines to fail (and may also cause
both to emit secondary bogons); however, the precise mechanics
of bogon-computron interaction are not yet understood.
Quantum bogodynamics is most often invoked to explain the
sharp increase in hardware and software failures in the
presence of suits; the latter emit bogons, which the former
absorb.

quantum cell
(foldoc) | quantum cell
(Or "quantum dot cell") A structure
comprising four quantum dots arranged in a square, with two
diagonally opposed dots containing electron charges. One
diagonal containing charges is arbitrarily defined as
representing a value of '1', the other as '0'. In a five-dot
cell, the fifth, central dot contains no charge.

automata.

quantum cell wire
(foldoc) | quantum cell wire
(Or "quantum wire", "binary wire")
Quantum cells arranged in a line to carry signals. Adjacent
cells with the same orientation are at a low energy state and
a change of orientation at one end of a quantum wire
propagates along the wire, transmitting a signal. However,
unlike conventional wire, since only the orientation of charge
pairs changes, no current flows.
Circuits created using quantum cell wires are referred to as
Quantum-dot Wireless Digital Circuits, see quantum dot,
Quantum-dot Cellular Automata.

quantum computing
A type of computer which uses the ability of
quantum systems, such as a collection of atoms, to be in many
different states at once. In theory, such superpositions
allow the computer to perform many different computations
simultaneously. This capability is combined with interference
among the states to produce answers to some problems, such as
factoring integers, much more rapidly than is possible with
conventional computers. In practice, such machines have not
yet been built due to their extreme sensitivity to noise.

quantum dot
(foldoc) | quantum dot
single-electron transistor
(Or "single-electron transistor") A location capable
of containing a single electrical charge; i.e., a single
electron of Coulomb charge. Physically, quantum dots are
nanometer-size semiconductor structures in which the
presence or absence of a quantum electron can be used to store
information.

quantum-dot cellular automata
(foldoc) | Quantum-dot Cellular Automata
QCA
(QCA) Quantum logic circuits created
by orientating pairs of quantum cells so that their relative
positions determine their affect on each other. This is
functionally analogous but structurally different from how
individual gates in integrated circuits are combined to
create logical and memory circuitry.
The advantages of quantum-dot cellular automata over
conventional circuitry are extremely small size/high density,
low power requirements, and potentially high processing
speeds. Disadvantages (in 2000) are difficulty of fabrication
and low yield.

quantum bogodynamics
(jargon) | quantum bogodynamics
/kwon'tm boh`goh·di:·nam´iks/, n.
A theory that characterizes the universe in terms of bogon sources (such as
politicians, used-car salesmen, TV evangelists, and suits in general),
bogon sinks (such as taxpayers and computers), and bogosity potential
fields. Bogon absorption, of course, causes human beings to behave
mindlessly and machines to fail (and may also cause both to emit secondary
bogons); however, the precise mechanics of the bogon-computron interaction
are not yet understood and remain to be elucidated. Quantum bogodynamics is
most often invoked to explain the sharp increase in hardware and software
failures in the presence of suits; the latter emit bogons, which the former
absorb. See bogon, computron, suit, psyton.
Here is a representative QBD theory: The bogon is a boson (integral spin,
+1 or -1), and has zero rest mass. In this respect it is very much like a
photon. However, it has a much greater momentum, thus explaining its
destructive effect on computer electronics and human nervous systems. The
corollary to this is that bogons also have tremendous inertia, and
therefore a bogon beam is deflected only with great difficulty. When the
bogon encounters its antiparticle, the cluon, they mutually annihilate each
other, releasing magic smoke. Furthermore 1 Lenat = 1 mole (6.022E23) of
bogons (see microLenat).

QUANTUM DAMNIFICATUS
(bouvier) | QUANTUM DAMNIFICATUS, equity practice. An issue directed by a court of
equity to be tried in a court of law, to ascertain by a trial before a jury,
the amount of damages suffered by the non-performance of some collateral
undertaking which a penalty has been given to secure. When such damages have
thus been ascertained the court will grant relief upon their payment. Jer.
on Jur. 477; 4 Bouv. Inst. n. 3913.

QUANTUM MERUIT
(bouvier) | QUANTUM MERUIT, pleading. As much as he has deserved. When a person employs
another to do work for him, without any agreement as to his compensation,
the law implies a promise from, the employer to the workman that he will pay
him for his services, as much as be may deserve or merit. In such case the
plaintiff may suggest in his declaration that the defendant promised to pay
him as much as he reasonably deserved, and then aver that his trouble was
worth such a sum of money, which the defendant has omitted to pay. This is
called an assumpsit on a quantum meruit. 2 Bl. Com. 162, 3 1 Vin. Ab. 346; 2
Phil. Ev. 82.
2. When there is an express contract for a stipulated amount and mode
of compensation for services, the plaintiff cannot abandon the contract and
resort to an action for a quantum meruit on an implied assumpsit. 18 John.

QUANTUM VALEBAT
(bouvier) | QUANTUM VALEBAT, pleading. As much as it was worth. When goods are sold,
without specifying any price, the law implies a promise from the buyer to
the seller that he will pay him for them as much as they were worth.
2. The plaintiff may, in such case, suggest in this declaration that
the defendant promised to pay him as much as the said goods were worth, and
then aver that they were worth so much, which the defendant has refused to
pay. Vide the authorities cited under the article Quantum meruit.
