May 6, 2021 —In quantum mechanics, the Heisenberg uncertainty principle dictates that the position and speed of an object cannot both be known fully precisely at the same time. Researchers now show that two ...
Mar. 10, 2022 —A research team has discovered a Heisenberg-limited metrology via weak-value amplification without using entangled ...
Oct. 8, 2020 —For 100 years scientists have disagreed on how to interpret quantum mechanics. A recent study supports an interpretation that is close to classical scientific ...
Feb. 10, 2021 —Researchers have used well-established cosmological observations to place tighter constraints on the quadratic model of the Generalized Uncertainty Principle, while discrediting the linear ...
July 14, 2021 —The quantum movements of a small glass sphere could be controlled for the first time in Vienna by combining microscopy with control engineering, setting the course for future quantum ...
Sep. 8, 2020 —Researchers used quantum optics to advance state-of-the-art microscopy and illuminate a path to detecting material properties with greater sensitivity than is possible with traditional ...
July 7, 2020 —Physicists have designed a quantum ''light squeezer'' that reduces quantum noise in an incoming laser beam by 15 percent. It is the first system of its kind to work at room ...
Apr. 8, 2022 —Physicists have developed the most sensitive method ever for measuring the potential energy of an atom (within a hundredth of a decillionth of a joule -- or 10-35 joule), and used it to validate one ...
Apr. 27, 2022 —Physicists are re-examining the foundations of quantum physics from the perspective of momentum and exploring what happens when the momentum of light is reduced to ...
Mar. 14, 2022 —Experimental physicists have succeeded for the first time in controlling protected quantum states - so-called dark states - in superconducting quantum bits. The entangled states are 500 times more ...
