Scientists have announced a large step towards the creation of a quantum computer

An international group of physicists has advanced in the creation of so-called quantum computer. We are talking about a computer perspective, which (in theory) It operates not bits, as qubits - quantum bits special, lining quantum register. Qubit - information paradigm, which can simultaneously be in several states: if the bit is either 0, or, then, for a qubit can be a superposition of these states.

Учёные заявили о большом шаге на пути создания квантового компьютера

The use of qubits instead of the usual bits in the long term and gives the opportunity to create a computer with incredible by today's standards characteristics.

Scientists Massachusetts Institute of Technology (USA) together with colleagues from a number of countries have been able for the first time in the history of research to fix the so-called temporal coherence of the qubit graphene. In other words, able to identify, in it may be in the same for some time (unique) states simultaneously zero and one. The higher the coherence time, the more you can do computing operations.

Graphene materials allow for effective fixation temporal coherence. The results are published in scientific journals Nature Nanotechnology.

of material:
Experts for the first time demonstrate the coherent qubit using graphene structure. coherence time 55 nanoseconds.

For reference: graphene - one of the carbon modifications. its uniqueness – in the two-dimensionality. The structure has a layer thickness of one atom. For the first time the work of the resulting graph was published by Russian scientists Andrei Geim and Konstantin Novoselov (Institute staff in Manchester). And consider their discoverers (so to speak, first recipients) graphene.

It is based on the creation of graphene, and was made possible breakthrough in the study of the ability of superconducting systems for their potential applications in the development of quantum computers. Scientists believe the work of fixing the temporal coherence of qubits using graphene big step towards the creation of this car of the future.
