Latest Quantum measurement Stories
The remarkable ability of an electron to exist in two places at once has been controlled in the most common electronic material â€“ silicon - for the first time.
Researchers have devised a new kind of random number generator, for encrypted communications and other uses, that is cryptographically secure, inherently private and â€“ most importantly â€“ certified random by laws of physics.
To exploit the quantum world to the fullest, a key commodity is entanglementâ€”the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another.
Chaotic behavior is the rule, not the exception, in the world we experience through our senses, the world governed by the laws of classical physics.
In comparison to classical physics, quantum physics predicts that the properties of a quantum mechanical system depend on the measurement context, i.e. whether or not other system measurements are carried out.
In his discussion of accelerated motion on page 60 of The Meaning of Relativity, Albert Einstein made an approximation that allowed him to develop the theory of relativity further.
In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum mechanics' directly.
University of Toronto quantum physicists Jeff Lundeen and Aephraim Steinberg have shown that Hardy's paradox, a proposal that has confounded physicists for over a decade, can be confirmed and ultimately resolved, a task which had seemingly been impossible to perform.
An $11 million grant from the National Institute of Standards and Technology (NIST) will help the University of California, Berkeley, build a state-of-the-art precision measurement laboratory in the planned new home for the astronomy department and part of the physics department.
In 2006, Andrew Jordan, professor of physics and astronomy at the University of Rochester, together with Alexander Korotkov at the University of California, Riverside, spelled out how to exploit a quantum quirk to accomplish a feat long thought impossible, and last week a research team at the University of California at Santa Barbara has tested the theory, proving it correct.
