Control of errors in quantum computers
The entangled state of three objects had already been made with photons and charged particles, but this is the first time that you get in a solid state device A group of researchers at Yale University was able to obtain for the first time a state entanglement of three qubits in solid form, perform an essential step to achieve these indipensabili random checks of possible errors in future quantum computers.
"The entanglement between three objects had been found so far with photons and charged particles. But this is the first time that you get in a solid state device that looks and behaves like a conventional processor," said Steven Girvin, paretcipato that the study now published in the pages of Nature. Last year was the first time developed a rudimentary first solid-state quantum processor that had proved unable to perform simple algorithm with two qubits.
In the new study, researchers were able to obtain, with a success rate of 88 percent of the attempts made, a state of placing the three-qubit entanglement in a state of superposition of two possibilities, in all three state 0, or all three in state 1. The particular state of entanglement thus obtained demonstrates for the first time the possibility to encode the quantum information of a single qubit through the so-called three-qubit repetition code: "This is the first step towards quantum error correction, as in a classical computer that takes advantage of extra qubits to allow the computer to operate correctly even in the presence of occasional errors," said Girvin.
Errors of this type may be due, exemplifies Girvin, for example by cosmic rays that can convert a qubit from 0 to 1 or vice versa. Replicating the qubit, the computer is able to check if all three are in the same state, as they should.
"Error correction is a kind of holy grail of quantum computing today, and it can be realized requires a minimum of three qubits. So what made it exciting step," said Schoelkopf, which led the research. (Gg)

If we now imagine that the NETWORK OF UNCONSCIOUS (see: www.inconsci.blogspot.com) communicate with "state of entanglement" (non-local Quantum Mechanics), we can assume that such errors also occur in the communications network and this would help explain many incorrect interpretations of what is received on a subconscious level (Which should not happen if all spiritual or metaphysical).
