IT Home reported on February 21 that normally, 1 qubit (qubits) corresponds to 1 quantum state (quantum state), but scientists have recently found a way to ultra-dense quantum computers1 quantum state can be stored on 16 antimony atoms.
Researchers at the University of New South Wales (UNSW) in Sydney have demonstrated that antimony (SB) atoms can possess 16 quantum states at the same time.
The antimony atom itself has 8 quantum states, in addition to its electrons providing an additional 2 quantum states, and by superimposing the antimony atom and antimony electrons, a total of 16 quantum states can be generated, which is like the 3D NAND of the future, where each cell can write 16 bits of data.
Scientists also say that the quantum states of antimony atoms and electrons can be controlled in four different ways, thereby improving the efficiency of qubits. Scientists say that the quantum state of antimony electrons can be controlled by magnetic field oscillation, and the rotation of antimony atoms can be controlled by magnetic resonance or electric fields.
Professor Andrea Morero, the first author of the study, said:
Our research topics are more complex and relatively slow, but they have the advantage of extreme information density.
There are 25 million atoms per square millimeter, and we have to control them one by one. The ability to accomplish this with magnetic, electric, or any combination of the two will open up many possibilities for us to leverage them as we scale our systems.
