Schrödinger's Cat with 20 Qubits

August 13, 2019

In quantum computing, a cat state - named after the famous analogy of Schrödinger's cat -- is a quantum state composed of two diametrically opposed conditions simultaneously. Together with experts from Forschungszentrum Jülich, an international team has now succeeded in placing 20 entangled quantum bits in such a state of superposition.

Dead or alive, left-spinning or right-spinning—in the quantum world particles such as the famous analogy of Schrödinger's cat can be all these things at the same time. [Postdoc Ahmed Omran and grad student Harry Levine, of Mikhail Lukin group, together with an international team of physicists] have now succeeded in transforming 20 entangled quantum bits into such a state of superposition. The generation of such atomic Schrödinger cat states is regarded as an important step in the development of quantum computers which could outperform classical computers in solving certain tasks...
