Schrödinger's cat with 20 qubits

Phys.org - 13 Aug 2019 17:31
Schrödinger's cat with 20Dead 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. An international team,... including researchers from several leading American universities, together with experts from Forschungszentrum Jülich, 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. The results were published in Science last Friday.

Counterintuitive physicsEver since the late 19th century, physicists have known about a counterintuitive property of some electric circuits called negative resistance. Typically, increasing the voltage in a circuit causes... the electric current to increase as well. But under some conditions, increasing the voltage can cause the current to decrease instead. This basically means that pushing harder on the electric charges actually slows them down.

Atomic 'Trojan horse' couldHow do researchers explore nature on its most fundamental level? They build "supermicroscopes" that can resolve atomic and subatomic details. This won't work with visible light, but they can probe the... tiniest dimensions of matter with beams of electrons, either by using them directly in particle colliders or by converting their energy into bright X-rays in X-ray lasers. At the heart of such scientific discovery machines are particle accelerators that first generate electrons at a source and then boost their energy in a series of accelerator cavities.
