Scientists make 'magic state' breakthrough after 20 years — without it, quantum computers can never be truly useful

Scientists have achieved a breakthrough in quantum computing by demonstrating "magic state distillation" on logical qubits for the first time. This process, crucial for running complex quantum algorithms, was performed on QuEra's Gemini quantum computer using Distance-3 and Distance-5 logical qubits. The achievement paves the way for fault-tolerant quantum computers that could potentially outperform classical supercomputers in solving complex problems.
