A new approach to realizing quantum mechanical compression

Scheme of nonclassical mechanical states of a resonator-qubit combination. A transmon qubit capacitively couples to acoustic mechanical modes of a separate sapphire slab, one of which is shown as a series of blue and red antinodes. Nonclassical mechanical states emerge from this interaction. Three vignettes reproduce Wigner functions of i) a squeezed vibrational state, ii) … Read more

Mechanical computers rely on kirigami cubes, not electronics

Researchers at North Carolina State University have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic components.

The discovery by Chinese scientists paves the way for the mechanical production of hybrid rice seeds

“For hybrid seed of the next generation productionthe use of male sterile lines with small grains to mechanically separate small hybrid seeds from the mixed crop is promising,” they said. The challenge was to find a gene that can cause a rice line to have a small grain size without reducing the number of seeds … Read more
