New research shows that it is possible to perfectly recover the original from the imperfect quantum copies. Scientists also propose a way that his could be done in practice.
Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. This study could have implications for quantum computers due to improvements in the transport of discrete amounts of information, known as qubits, that are encoded in electrons.
A team of scientists has built a quantum computer in a diamond, the first of its kind to include protection against "decoherence" -- noise that prevents the computer from functioning properly.
Scientists have demonstrated a new kind of detector for sound at the level of quietness of quantum mechanics. The result offers prospects of a new class of quantum hybrid circuits that mix acoustic elements with electrical ones, and may help illuminate new phenomena of quantum physics.
Addressing a half-century-old question, engineers have conclusively determined how collective electron oscillations, called plasmons, behave in individual metal particles as small as just a few nanometers in diameter. This knowledge may open up new avenues in nanotechnology ranging from solar catalysis to biomedical therapeutics.
