Scientists of IBM and the University of Stanford used ' Shor's algorithm ', 1994 a developed method, in order to find with a molecular quantum computer the prime number divisors of the number of 15. This operation is too with difficulty for normal computers and therefore long numeric codes for the coding of data is used. 1994 showed the Bell mathematician Peter Shor that a quantum computer can divide a large number into its prime factors and substantially faster than a classical computer. Would you like to be informed regularly about new technologies? Then you subscribe our new type character contrary to conventional electronics use quantum computer the spin of an atomic nucleus around qubit (quantum bits) to represent. The efficiency quantum computers is based to 0 and 1 on the characteristic one qubits to be simultaneous to be able. 7 qubits is enough straight out around the simplest form of Shor's algorithm to compute. For the purpose a new molecule with 7 nuclear spins was produced. The spins can interact and become with one another by radio frequency pulse programmed. The result can be read with NMR (nuclear magnetic resonance) instruments. The scientists steered in a Viole 10(18) of these molecules in such a way the fact that they implemented Shor's algorithm and identified correctly 3 and 5 as the factors of 15. During the reading of the result the Dekohaerenz prepares problems: Each interaction from the outside can destroy the quantum information. The scientists created it the Dekohaerenz process to modelieren and accurately forecast and optimized thereby the quantum circuits. NMR based quantum computers are not pure laboratory experiments and commercial are still on many years to be expected. So it is to be developed very heavily fitting molecules for dividing larger numbers, because but thousands of qubits are needed. In addition the NMR technology concerned at its borders and researchers believes that it cannot be high-scaled on detection of 10,-20 qubits. Now the scientists look for new systems, which can be more simply high-scaled.
