The field of experimental quantum communication promises ways of efficient and unconditional secure information exchange in quantum states. The possibility of transferring quantum information forms a cornerstone of the emerging ...
A Persian adage, notably wielded by Abe Lincoln and the band OK Go, expresses the ephemeral nature of the world: "This, too, shall pass."
Scientists and journalists alike are disputing claims made by an international team of researchers that they had entangled a tardigrade with superconducting qubits. Their paper is published on the arXiv preprint server. Virtually ...
Unlike the jumble of frequencies produced by the light that surrounds us in daily life, each frequency of light in a specialized light source known as a "soliton" frequency comb oscillates in unison, generating solitary pulses ...
Â鶹ÒùÔºicists construct theories to describe nature. Let us explain it through an analogy with something that we can do in our everyday life, like going on a hike in the mountains. To avoid getting lost, we generally use a map. ...
Flaws in diamonds—atomic defects where carbon is replaced by nitrogen or another element—may offer a close-to-perfect interface for quantum computing, a proposed communications exchange that promises to be faster and ...
In a study published in Â鶹ÒùÔºical Review Letters, the team led by Academician Guo Guangcan from the University of Science and Technology of China of the Chinese Academy of Sciences (CAS), collaborating with Prof. Wang Zizhu ...
What would it be like if we lived in a flat two-dimensional world? Â鶹ÒùÔºicists predict that quantum mechanics would be even stranger in that case, resulting in exotic particles—so-called "anyons"— that cannot exist in ...
In 1973, physicist Philip W. Anderson theorized the existence of a new state of matter that has been a major focus of the field, especially in the race for quantum computers.
Quantum computer and many other quantum technologies rely on the generation of quantum-entangled pairs of electrons. However, the systems developed so far typically produce a noisy and random flow of entangled electrons, ...
