Opinion The scientific community celebrated April 14 as World Quantum Day to raise awareness of quantum science’s impact across diverse fields The world of science is on the cusp of a transformative era driven by the burgeoning field of quantum technology. Quantum science is founded on several key principles that underpin the behaviour of particles and systems at the quantum scale. The term “quantum scale” refers to the realm of physics that deals with phenomena occurring at very small scales, typically at the level of atoms, subatomic particles and fundamental particles. It encompasses the principles of quantum mechanics, which govern...

A phenomenon of quantum mechanics known as superposition can impact timekeeping in high-precision clocks, according to a theoretical study from Dartmouth College, Saint Anselm College and Santa Clara University. Research describing the effect shows that superposition—the ability of an atom to exist in more than one state at the same time—leads to a correction in atomic clocks known as "quantum time dilation." The research, published in the journal Nature Communications, takes into account quantum effects beyond Albert Einstein's theory of relativity to make a new prediction about the nature of time. In the early 1900s, Albert Einstein presented a revolutionary...

Quantum mechanics’ core assumption is that on the smallest scales, atomic properties are quantized...For example, an electron can be in a lowest-energy state, but if you add a little more energy, it doesn’t slowly transition into the new higher-energy state. Rather, it unpredictably snaps into the new state. If you’re not looking at it, the atom can take on intermediate states—but these aren’t midway points. The atom would be in both states at the same time, and then once you observed it, it would immediately snap into one state or the other. The team’s artificial atom is an experimental apparatus...

Yale physicists have given Schrödinger's cat a second box to play in. Credit: Michael S. Helfenbein/Yale University ====================================================================================================================== Yale physicists have given Schrödinger's famous cat a second box to play in, and the result may help further the quest for reliable quantum computing. Schrödinger's cat is a well-known paradox that applies the concept of superposition in quantum physics to objects encountered in everyday life. The idea is that a cat is placed in a sealed box with a radioactive source and a poison that will be triggered if an atom of the radioactive substance decays. Quantum physics suggests that the...

Where did the idea of “millions of years” come from? All of our media outlets push evolution and “millions of years” ideas on the public. Even children’s cartoons reflect evolutionary philosophy! In an episode of the cartoon SpongeBob SquarePants, entitled “SpongeBob B.C.,” the narrator begins: “Ah, dawn breaks over the primordial sea. It is here that millions of years ago, life began taking its first clumsy steps out of the darkness, opening its newly formed eyeballs to stare into the blinding light of intelligence.” Unfortunately, large segments of the church have swallowed the millions-of-years evolutionary history hook, line, and sinker....

Physicists seek to put one thing in two placesSept. 25, 2006 Special to World Science  Physi­cists say they have made an ob­ject move just by watch­ing it. This is in­spir­ing them to a still bold­er proj­ect: put­ting a small, or­di­nary thing in­to two places at once. It may be a “fan­ta­sy,” ad­mits Keith Schwab of Cor­nell Uni­ver­si­ty in Ith­a­ca, N.Y., one of the re­search­ers. Then again, the first ef­fect seemed that way not long ago, and the sec­ond is re­lat­ed. The gray sliv­er reach­ing from top to bot­tom, slanted in the im­age, is a na­no­me­chan­i­cal re­s­o­na­tor, a sub-mi­c­ro­s­co­pic de­vice...
