Inefficient qubits are not fit for the desktop

Quantum computers might one day be able to factor huge numbers or search vast databases, but when it comes to word-processing or accessing the internet, forget it. That is the conclusion of two US physicists, who have calculated the energy efficiency of a quantum computer and compared it with that of a traditional, classical machine. Julio Gea-Banacloche of the University of Arkansas and Laszlo Kish of Texas A&M University say that classical computers are far better at carrying out general-purpose tasks (Fluctuation and Noise Letters 3 C3).
