Heisenberg’s revenge: Energy need may cap size, ability of quantum computers

The energy required to create an accurate quantum computer may limit the ability of scientists to make these novel devices small, fast, cheap and efficient, says a University of Arkansas researcher. Quantum computing relies on using single atomic particles as units for information storage. Manipulating this information requires pulsed electromagnetic fields?which contain energy. The researcher found that the energy needed to perform a calculation is inversely proportional to the error rate: In other words, more energy means less uncertainty.
