Квантовая криптография, русский
Система, основанная на квантовой - механические принципы.

Cryptography, английский
- The art of protecting information by transforming it (encrypting it) into an unreadable format, called cipher text.
- The science of turning plain language into unintelligible text for secrecy and security. typically the development of codes or ciphers.
- Криптография
- The study or analysis of codes and encoding methods used to secure information. cryptography is used to provide confidentiality, data integrity, authentication (entity and data origin), and nonrepudiation.
Cryptography application programming interface, английский
An (api) that is provided as part of microsoft windows. cryptoapi provides a set of functions that allow applications to encrypt or digitally sign data in a flexible manner while providing protection for the user’s sensitive private key data. actual cryptographic operations are performed by independent modules known as (csps).
Cryptography next generation, английский
A replacement of the cryptoapi that enables support for suite b cryptographic algorithms such as elliptic curve cryptography (ecc).
Quantum, латинский
Quantum, английский
- Шаг квантования
- Квант; квант времени
- A brief period of time when a given thread executes in a multitasking operating system. it performs the multitasking before it is rescheduled against other threads with the same priority. previously known as a time slice.” quantum computing / theory
- If the magnitude of a quantity is always an integral multiple of a definite unit, then that unit is called the quantum of the quantity. the photon is a quantum of the electromagnetic field and the meson is considered to be the quantum of the nuclear field.
Quantum (rt), английский
A discrete amount of radiation energy. the quantum energy is e=hu, where u is the frequency of the radiation and h is plank’s constant.
Quantum amplification by stimulated emission, английский
Of radiation квазер, квантовомеханический генератор
Quantum cascade lasers, английский
Semiconductor lasers relying on intersubband transitions, normally emitting in the mid-infrared spectral region
Quantum computer, английский
A machine that relies on the properties of quantum mechanics to perform computations. quantum computers encode information in qubits, which can exist in a linear combination of two states. these states can be physically realized in a number of ways, such as superconducting circuits, trapped ions, optical lattices, and linear optics. computation is performed by operating on the state of these qubits using quantum logic gates. for example, if the qubit is realized as an ion, the quantum logic gate might manipulate the ion’s energy state with lasers.
Quantum confined atoms (qca), английский
Quantum confinement effect, английский
Atoms caged inside nanocrystals.
Quantum cryptanalysis, английский
Quantum cryptographic protocol, английский
Quantum cryptographic system, английский
Quantum crystallite (quantum dot), английский
Quantum defect, английский
Energy difference between pump and laser photons
Quantum dot, английский
A nanoscale crystalline structure made from cadmium selenide that absorbs white light and then re-emits it a couple of nanoseconds later in a specific color. the quantum dot was originally investigated for possible computer applications. recently, researchers are investigating the use of quantum dots for medical applications, using the molecule-sized crystals as probes to track antibodies, viruses, proteins, or dna within the human body.
Quantum dot nanocrystals (qdn), английский
Quantum dots, английский
Microscopic structures confining charge carriers in three dimensions
Quantum efficiency, английский
- The ratio of hole-electron pairs or photoelectrons to the number of photons received by a photodetector. the quantum efficiency can be as high as 80% for an apd and 25% for a pmt.
- Percentage of input photons which contribute to a desired effect
Information, английский
- Knowledge of a particular event or situation, or knowledge communicated or received concerning a particular fact.
- Информация
- Facts about something have you any information about the treatment of sunburn? the police won’t give us any information about how the accident happened. you haven’t given me enough information about when your symptoms started. that’s a very useful piece or bit of information. (note: no plural: some information; a piece of information.)
- N информация | attr. информационный flow, structure source of ~ источник информации 1 ранее использовался в более широком значении как ‘умозаключе- ние’. 2 получение выводных данных в процессе обработки информации и/или языка и само выводное знание, умозаключение; мыслительная операция, в ходе которой человек выходит за пределы данных в тек- сте сведений и получает новую информацию. 3 аффикс, вставляемый внутрь корня слова при словообразовании или словоизменении.
- In admiralty courts, implies a clause introduced into a citation, intimating that in the event of a party cited not appearing, the court will proceed in his absence.
- Информация; данные; сведения
- Координационный комитет ин4юрмации о проектируемых и возводимых объектах строительства
- Literally that which forms within, but more adequately
- Data that has been recorded, classified, organized, related or interpreted so that meaning is apparent.
- Contextualised data providing answer to a certain question decreasing uncertainty.
- Информация, сведения
Mechanical, английский

Spectroscopy, английский
- Methods where the interaction of light with matter is utilized
- Спектроскопия ко к данному компоненту пробы, а не к каким-либо другим присутствующим ингредиентам.
- Спектроскопия. раздел физики, посвященный изучению спектров. менее распространенный термин спектрометрия может относиться к методам их количественного измерения, а термин спектрография относится к методам, в которых используется фоторегистрация и другие виды записи. применение спектроскопических методов в области аналитической химии получило название спектрального химического анализа. все эти методы основаны на взаимодействии электромагнитного излучения с веществом и обнаружении квантов энергии, испускаемых или поглощаемых при переходе вещества из одного энергетического состояния в другое. эмиссионная спектроскопия изучает спектры, образующиеся при дисперсии излучения, испускаемого возбуждаемым источником, абсорбционная спектроскопия — спектры, образующиеся , при поглощении (при определенных длинах волн) энергии излучения, испускаемого непрерывно действующим источником. для изучения спектральных линий атомов при- 9* 131
- The identification of materials by the analysis of their spectra.
- Spectrophotometry or spectroradiometry in which the spectrum, rather than being analyzed only by a processing unit, is presented as a digital signal for computer analysis or in a visible form to the operator for organoleptic examination.
- Spectrophotometry or spectroradiometry in which the spectrum, rather than being analyzed only by a processing unit, is presented in a visible form to the operator for organoleptic examination.
- The study of how radiant energy and a medium interact with respect to wavelength or frequency. see also polychromator spectrometer; spectrofluorometer; spectrophotometer; spectroradiometer.
