logic operation

[′läj·ik ‚äp·ə′rā·shən]
(computer science)
A nonarithmetical operation in a computer, such as comparing, selecting, making references, matching, sorting, and merging, where logical yes-or-no quantities are involved.

logic operation

An operation that analyzes one or more inputs and generates a particular output based on a set of rules. See AND-OR-NOT and Boolean logic.

"We verified that our logic operation works on all input states of two quantum bits with 85 to 87% probability -- far from perfect, but it is a start," NIST physicist Dietrich Leibfried said.
The Option nodes basically represent the OR boolean logic operations. So, if the condition set under any Option nodes associated with a particular local memory is true, then the RLO value stored in that local memory is also true.
The fuzzy measure [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] also provides fulfilling of logic operation "And".
Invigorating the idea of computers based on fluids instead of silicon, researchers at the National Institute of Standards and Technology (NIST) have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ions (charged atoms) in graphene (a sheet of carbon atoms) floating in saline solution.
Performing logic operations on a PCB is the job of moving energy on and off of sections of transmission line.
(3) A computer program for determining informative types of relations between concepts was created to perform these logic operations automatically.
The cross-correlations are implemented as logic operations between answers.
The most common electronic computers apply logic operations to streams of 1's and 0's to produce more complex functions, which in turn, create software.
Circuits that can perform logic operations at the push of a button are a dime-a-dozen these days, but a breakthrough by researchers in the USA has meant they can be smaller and simpler than ever before.
In the new demonstration, NIST researchers repeatedly performed a combined sequence of five quantum logic operations and ten transport operations while reliably maintaining the 0s and 1s of the binary data stored in the ions, which serve as quantum bits (qubits) for a hypothetical quantum computer, and retaining the ability to subsequently manipulate this information.
In more recent years, teams led by Awschalom and Wrachtrup performed the first quantum logic operations between two diamond qubits.
"The prospect of making both logic and memory devices with the same material is very intriguing, and at this small a scale, it's almost unheard of." The physical model requires testing in crucial ways, but it provides an important framework for future research that aims to create devices that use a single electron for logic operations or to store a bit of information.
