Dutch improve error detection for quantum computer




Scientists from Delft University of Technology have developed a method in quantum information systems to check for errors and improve them if necessary. This should ensure that the storage and readout of quantum states is accurate.

The results of the study by the DUT itself disclosed , whereby a scientific paper on the subject was published in the journal Nature Nanotechnology. According to the scientists, it is possible to detect in quantum states, which in quantum computers serve as substitutes for conventional bits, by utilizing entanglement usage errors, a quantum mechanical phenomenon in which two or more particles together “linking” where they are no longer independent of can be written. each other

Researchers at TU Delft have developed a method in diamond to intertwine. Multiple quantum states, which serve as qubits, with each By comparing the states of the qubits entangled with each other errors can be detected, after which the system also is able to restore them. For example, the scientists demonstrated that the spin of the entangled qubits could be measured and, in which the stored information was maintained restored: one of the problems with error detection in quantum mechanical systems is that the information does not remain intact as it is measured.

The scientists also managed to perform. Experiments at room temperature Much research into applications for quantum computers takes place at low temperatures, something the implementation difficult. According to TU Delft system that detects and repairs errors should be expanded so that it is more versatile.
