Physicists have created the first hybrid qubit

Scientists from the US and the UK for the first time created a qubit from two different kinds of ions. American scientists were able to link the magnesium ions and ions of beryllium, the British physics "entangled" ions of two different isotopes of the same substance - calcium-40 and calcium-43. This will allow scientists hope to create in the future universal quantum computers.

Both studies were published in the magazine Nature. American scientists have managed to create the first prototype of qubits - the smallest element for storing information in a quantum computer - on the basis of magnesium and beryllium ions. This was possible thanks to a special laser system control spin of charged particles. As the study's authors hope it will create in the near future supersensitive atomic clock and universal quantum computers.

"Hybrid quantum computers provide the unique benefits that have different quantum systems - said Ting Tan of the National Institute of Standards and Technology in Boulder. - Each ion type is unique: some are better suited for storage of information and others are more suitable for transmission of information. "

British scientists were able to link the two ions of different isotopes of the same substance - calcium-40 and calcium-43. The first one is better suited to the role of the channel for the transmission of quantum information, and the second is the most reliable basis for quantum memory cells.
