WHAT QUANTUM PHYSICS MEANS TO YOU -- FOR $1Chet Raymo
More babies’ books on quantum physics means more children will receive a boost in early life. 更多关于量子力学的婴儿书籍,意味着更多的孩子可以在童年得到提升。 More importantly, the science-popularization books are written so that they’re easy enough to read that even children can understand. Rat...
In physics, a quantum is the smallest possible discrete unit of any physical property. It usually refers to properties of atomic or subatomic particles, such as electrons, neutrinos, and photons. What is a qubit? A qubit is the basic unit of information in quantum computing. Qubits play a...
The current theories of quantum physics and general relativity on their own do not allow us to study situations in which the gravitational source is quantum. Here, we propose a strategy to determine the dynamics of objects in the presence of mass configurations in superposition, and hence an ind...
The principle of quantum computing is based on one of the strangest phenomena in quantum physics: quantum entanglement. The ancients would see modern electronic technology as akin to witchcraft; most people today would have a similar view of future quantum computing technology. ...

Specifically, there is never any causal “quantum-wave” propagation in spacetime. This means that classical physics, II, can never be the limit ℏ→0ℏ→0 of “pure” quantum theory, I. The quantum description of a system of N entities (for 𝑁>1N>1) cannot be embedded in real ...
In recent years, IBM [12] and Google [13] have realized prototypes of commercial quantum computers. They use superconducting qubits by means of the superposition of supercurrents in Josephson junctions, which require very low temperatures to operate. Also, superconducting opto-electronic circuits ...
Microsoft’s plan to build a quantum computing ecosystem is based on Freedman’s field of math and a branch of physics so seemingly mystical its early pioneers invoked philosophy and spirituality to describe it, and its later disciples attracted funding and support from self-help gurus ...
