The very core of quantum computing lies in its hardware – the qubits that power these revolutionary machines. Significant progress is being made in the race to build robust and scalable quantum processors.
The Race for Better Qubits: Superconducting, Trapped Ion, and Beyond
Today’s landscape is dominated by a few key qubit technologies. Researchers are relentlessly working to reduce superconducting qubit error rates, which remain a primary hurdle for practical applications. While superconducting qubits offer speed, the comparison of trapped ion vs superconducting qubit scalability is a hot topic. Trapped ions boast longer coherence times and often higher fidelity, making them strong contenders for future fault-tolerant systems, though scaling them presents unique challenges.
