World's first single-atom quantum computer moves closer to reality

An Australian team of scientists has managed to make two atom qubits "talk" to each other, which, according to them, is a "major milestone" in the race to create world's first single-atom quantum computer. As part of a study, published in the journal Nature Communications, the scientists led by University of New South Wales (UNSW) professor Michelle Simmons managed to create qubits from precisely positioned individual phosphorus atoms in a silicon chip. Once positioned, the scientists could make two of those atom qubits communicate and correlate with each other. The team of scientists led by Simmons is said to be the only group in the world to witness the exact position of their qubits in the solid state. Prior to the latest advance, the scientists recently achieved two other breakthroughs using the same approach to building a quantum c...
