Physicists implement a version of Maxwell’s famous thought experiment for reducing entropy

Reduced entropy in a three-dimensional lattice of super-cooled, laser-trapped atoms could help speed progress toward creating quantum computers. A team of researchers at Penn State can rearrange a randomly distributed array of atoms into neatly organized blocks, thus performing the function of a “Maxwell’s demon”—a thought experiment from the 1870s that challenged the second law […]

Researchers ‘teleport’ a quantum gate

Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the “teleportation” of a quantum gate between two qubits, on demand. The findings appear online Sept. 5 in the journal Nature. The key principle behind this new work is quantum teleportation, a unique feature of quantum mechanics […]
