BAD HARDWARE WEEK

A method of simulating a molecular system using a hybrid computer is provided. The hybrid computer comprises a classical computer and a quantum computer. The method uses atomic coordinates {right arrow over (R)}n and atomic charges Zn of a molecular system to compute a ground state energy of the molecular system using the quantum computer. The ground state energy is returned to the classical computer and the atomic coordinates are geometrically optimized on the classical computer based on information about the returned ground state energy of the atomic coordinates in order to produce a new set of atomic coordinates {right arrow over (R)}?n for the molecular system. These steps are optionally repeated in accordance with a refinement algorithm until a predetermined termination condition is achieved

1. It actually uses artificial atoms to simulate real ones.
2. It is not a general purpose computer design. It only simulates atoms clusters. Thus, for any new cluster simulation it needs a new QASIC chip.
3. It works not hotter than a few milli Kelvins close to aboslute zero. More qubits will heat chip and destroy the quantum coherence, its basic working principle.
4. Quantum fluctuations are inherent part of its working principle too. But, did D-wave company solve those problems as it boldly claims? More computing useful qubits means more errors, and overall less correct computing results. That further implies more repeated computings and bigger number of inputs for majority voting in the end. Without some miraculous error correcting breaktrough mechanism, quantum computing is self restricting in useful computing outcome.

Seems that practical use of quantum computer will still wait until the year 2020.
Bah.
