Scientists have developed a material designed to ‘quantumlicht’ that enables faster communication in computer systems is possible. It will also adjust the properties of photons, the basis for quantumcomputers.
With specially developed materials have properties that can be individually fired photons, particles of which light is composed, edited. Thus, the particles of light used to information store, said the scientists from the American Purdue university. The photons must be used to gather information and then also to be able to read. Especially the read-out of qubits, the bits that with quantum mechanical properties of particles work, it is currently still a stumbling block for quantumcomputers. By making use of these materials may be light on the unusual way be scattered, for example, in hyperboolvorm.
One of the suggested methods is the linking of individual photons with the so-called plasmonen; ‘quasideeltjes’ which consist of oscillating electrons in the charged particles. A nanodraad with these components could be used to get information to store and to read. The quantumstaat of the material used determines the ‘routing’ of the light, which can be used in a quantum computer. In earlier scientific research showed that Dutch scientists already see plasmongolven to be able to use computer technology. The pair of plasmonen with photons must have a stable source of individual photons produce for use in a quantum computer.
For the development of the quantum computer, which in the long term the conventional computer have to be replaced, are different particles tested on their abilities to a qubit. These quantum bits differ from conventional bits, because they are in superposition at the same time, the values 0 and 1. Often uses the spin of electrons to a qubit.
Quantumcomputers have the potential to be many times faster than conventional computers, but there is still much research needed to the necessary quantumbits, or qubits. By making use of light can not only qubits are made; optical communication can be many times faster than conventional methods.
