Schrödinger's cat with 20 qubits

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. An international team, including researchers from ...

Researchers build acoustic tractor beam

(Phys.org) —A team of researchers with members from the U.K., Scotland and the U.S. has built a functioning acoustic tractor beam in a lab—one that is able to pull objects of centimeter size. In their paper published ...

Micro-ear lets scientists eavesdrop on the micro-world

(PhysOrg.com) -- Acting as a microscope for sound, a new device called a micro-ear could make objects on the micro-scale audible. The device could enable scientists to listen to the sounds that cells and bacteria make as ...

Cooling with light

ETH researchers have cooled a nanoparticle to a record low temperature, thanks to a sophisticated experimental set-up that uses scattered laser light for cooling. Until now, no one has ever cooled a nanoparticle to such ...

Researchers develop new variant of Maxwell's demon at nanoscale

Maxwell's demon is a machine proposed by James Clerk Maxwell in 1867. The hypothetical machine would use thermal fluctuations to obtain energy, apparently violating the second principle of thermodynamics. Now, researchers ...
