Quantum engineers at UNSW Sydney have placed a ‘Schrödinger’s cat‘—the famous paradox of quantum superposition where a system exists simultaneously in a quantum superposition, in this case being both dead and alive—inside the nucleus of a single antimony atom on a silicon chip. “Antimony is a heavy atom, which possesses a large nuclear spin—meaning a…
Alice & Bob outlines roadmap to 100 logical qubits by 2030
Alice & Bob, a company specializing in quantum computing, has released its first white paper and accompanying five-year roadmap. The document highlights the company’s strategy to develop practical quantum computing using its proprietary cat qubit technology. This technology aims to achieve high-fidelity logical qubits with lower hardware and energy demands than other approaches. The roadmap…
