DARPA program breakthrough promises more practical quantum computers

The DARPA program ONISQ has achieved a breakthrough in quantum computing by creating the world’s first quantum circuit with logical quantum bits (qubits).

Quantum computing has the potential to revolutionize various fields by exploiting quantum effects and complex mathematics to significantly speed up information processing. However, the high error rate in quantum computing has been a challenge. DARPA’s approach involves using Rydberg qubits, which have the advantage of being homogeneous, allowing for rapid scaling and easy manipulation using lasers. This enables dynamic reconfiguration and transportability of logical qubits on a quantum chip, overcoming previous error-prone methods. DARPA has connected 48 logical qubits so far, paving the way for scalable quantum computing processors with less complexity than originally anticipated.
