Artificial atoms create stable qubits for quantum computing | NextBigFuture.com

Researchers at UNSW Sydney have made improved qubits using concepts from high school chemistry. Above -A silicon qubit high-frequency measurement stage, which is positioned inside a dilution refrigerator to cool the chip to around 0.1 degrees above absolute zero. Picture: UNSW/Ken Leanfore UNSW Sydney have created artificial atoms in silicon chips that offer improved stability for quantum computing. In a paper published today in Nature Communications, UNSW quantum computing researchers describe how they created artificial atoms in a silicon ‘quantum dot’, a tiny space in a quantum circuit where electrons are used as qubits (or quantum bits), the basic units
