Schema d'uso:
a quantum of [energy/charge/light]
When the atom falls to a lower energy level, it emits a single quantum of light.
Amikor az atom alacsonyabb energiaszintre kerül, egyetlen fénykvantumot bocsát ki.
In this experiment, each electron absorbs exactly one quantum of energy.
Ebben a kísérletben minden elektron pontosan egy energiakvantumot nyel el.
The theory treats radiation as made up of separate quanta rather than a continuous wave.
Esempi per chi studia
The atom gives off one quantum of light.
Az atom egy fénykvantumot bocsát ki.
Each quantum of energy is very small.
Minden energiakvantum nagyon kicsi.
In this model, energy comes in tiny pieces called quanta, one quantum at a time.
Errore comune:
Learners sometimes think 'quantum' means 'very large' because of the phrase 'a quantum leap'. In physics, a quantum is actually a very small, discrete unit, not a large amount.
Significato
smallest discrete unit in physics
Collocazioni
quantum of energy
|quantum of action
|single quantum
|emit a quantum
|absorb a quantum
Sinonimi
discrete unit (More general and less technical; does not specifically imply quantum physics.)
Contrari
continuum (Describes something changing smoothly without separate units, opposite to discrete quanta.)

Definizione
A very small, single unit of energy or another physical thing in quantum physics.
The smallest possible discrete amount of energy, or of another physical quantity, that can exist according to the rules of quantum physics.

Schema d'uso:
quantum [noun]
Quantum mechanics has changed our understanding of how particles behave.
A kvantummechanika megváltoztatta a részecskék viselkedéséről alkotott képünket.
She is doing her PhD in quantum information science.
Kvantuminformáció-tudományból doktorál.
Quantum computers use quantum bits to process information in new ways.
Esempi per chi studia
He studies quantum physics at university.
Az egyetemen kvantumfizikát tanul.
A quantum computer works in a different way from a normal computer.
A kvantumszámítógép másképp működik, mint egy hagyományos számítógép.
This is a basic idea in quantum theory.
Errore comune:
Learners sometimes use 'quantum' by itself to mean 'a big change' in general situations. For that idea, English normally uses the full expression 'a quantum leap', not just 'a quantum'.
Significato
relating to quantum physics
Collocazioni
quantum mechanics
|quantum physics
|quantum computer
|quantum theory
|quantum state
|quantum effect
Sinonimi
subatomic (Often overlaps in talking about very small particles, but 'subatomic' does not always imply quantum theory specifically.)
Contrari
classical (In physics, refers to non-quantum theories like Newtonian mechanics or classical electromagnetism.)
Temi

Definizione
About quantum physics or quantum effects at a very small scale.
Relating to or based on quantum theory, especially the behavior of matter and energy at very small scales.

a quantum of [uncountable noun]
The court found that there was a sufficient quantum of evidence to proceed.
A bíróság úgy találta, hogy elegendő mennyiségű bizonyíték áll rendelkezésre az eljárás folytatásához.
A minimal quantum of support is necessary for the proposal to move forward.
A javaslat továbblépéséhez minimális mértékű támogatás szükséges.
Researchers stress that only a small quantum of data was available at the time.
Esempi per chi studia

A bíró szerint nagy mennyiségű bizonyíték volt.
We still do not have the right quantum of data.
Még mindig nem áll rendelkezésünkre a megfelelő mennyiségű adat.
A small quantum of help made a big difference.
Errore comune:
Learners may overuse this sense in everyday speech. In normal conversation, people usually say 'amount' or 'a lot of' instead of 'a quantum of'.
Significato
specific measurable amount
Collocazioni
a quantum of evidence
|a quantum of work
|a quantum of comfort
|a quantum of proof
|sufficient quantum of
Sinonimi
amount (More common and general; 'quantum' sounds more formal and technical.)
Contrari
lack (Emphasizes the absence of an amount where a quantum or sufficient quantity would be expected.)

Schema d'uso:
the quantum of [damages/compensation]
The parties agreed on liability but not on the quantum of damages.
A felek a felelősség kérdésében megegyeztek, de a kártérítés összegében nem.
The judge reduced the quantum of compensation awarded to the claimant.
A bíró csökkentette a felperesnek megítélt kártérítés összegét.
There is an ongoing appeal concerning the quantum in this case.
Esempi per chi studia
The lawyer argued that the quantum of damages was too low.

They only fight about the quantum of compensation now.
Most már csak a kártérítés összegéről vitatkoznak.
The court must decide the quantum before the case can end.
Errore comune:
Learners sometimes think 'quantum' in legal texts still refers to physics. In law, it simply means the amount of money to be paid, especially as damages or compensation.
Significato
amount of legal damages
Collocazioni
quantum of damages
|quantum of compensation
|assess the quantum
|determine the quantum
|dispute over quantum
Sinonimi
amount (General term; does not carry the specific legal sense of an assessed sum in a court case.)
Contrari
liability (In legal language, liability is responsibility for harm, while quantum is the size of the payment; they are complementary rather than strict opposites but contrast different aspects of a case.)
Temi

|finance

Definizione
In legal English, the sum of money that someone must pay as damages or compensation.
In law, the amount of money that a court decides must be paid as damages or compensation.
