Sentences with phrase «quantum processes»
"quantum processes" refer to activities or events that happen at the smallest scale in the universe. They involve the behavior and interactions of subatomic particles, such as electrons and photons, which follow the rules of quantum mechanics. These processes can have unique and sometimes strange properties that are different from the way things work in our everyday world. Full definition

Harvard researchers have developed a specialized quantum computer, known as a quantum simulator, which could be used to shed new light on a host of complex quantum processes, from the connection between quantum mechanics and material properties to investigating new phases of matter and solving complex real - world optimization problems.
Meanwhile, the ampere's definition is so impractical that electrical researchers have had to turn to a definition outside the SI system based on quantum processes instead.
For example, quantum physicist David Bohm speculated in his 1954 textbook that there may be some relationship between quantum processes and thought processes.5 He later became convinced of what he called the «unbroken wholeness» of reality, asserting: «The primary emphasis is now on undivided wholeness, in which the observing instrument is not separable from what is observed.»
As a result, calculating even a prosaic quantum process — an electron travelling...
Four decades ago, he realized that a black hole's event horizon is inherently leaky; quantum processes allow a slow but steady flow of particles away from the black hole, a process now known as Hawking radiation.
Stuart Hameroff, an anesthesiologist who has spent many years studying brain functions, has collaborated with renowned Oxford University polymath Roger Penrose on a model that explains consciousness as the result of quantum processes occurring in tiny structures called microtubules in brain cells.
The evolving block universe may be correct, Callender says, but before Ellis can convince most of his peers, he will need to give a more rigorous explanation of how quantum processes, which usually affect only subatomic objects in experiments, cascade upward to create an effect across the cosmos.
Another objection is that vast swaths of the universe are devoid of people to observe quantum processes, which physicists traditionally say is what triggers particles to transform from their uncertain superpositions into defined states.
«Ultra cold atoms open up a door to recreate and study fundamental quantum processes in the lab,» says Professor Jörg Schmiedmayer (VCQ, TU Wien).
Paul Benioff of Argonne National Laboratory in Illinois showed the possibility of using quantum processes to compute by 1980.

There is Penrose the neuroscientist, who developed a controversial theory linking consciousness to quantum processes in the brain.
He made the connection between the quantum possibilities in the universe and the quantum processes in the brain,» Hameroff says.
The information escapes through a quantum process called entanglement, in which objects are not independent if they have interacted with each other or come into being through the same process.

At that point, the quantum process collapsed, and the electrons» energy followed that single, most effective path.
Ronald Walsworth, an atomic physicist at Harvard University in Cambridge, Massachusetts, whose team made a tentative suggestion in 2010 that the quantum Zeno effect operates in diamond, says that evidence is growing, but that it will probably need to be clearer that the disruption of oscillations is due to the quantum process, and not other effects, before it can be used for quantum computing.
In a jellyfish, that source is the aequorin protein, which transfers its blue light to GFP by a quantum process that some scientists compare to mind - reading — unlike sound waves, energy moves from one molecule to the other in the absence of any medium.
What happens to a molecule when a photon hits it can not be described in simple terms of classical mechanics, it's deeply a quantum process.
