IBM and Rigetti comparison

IBM IBM Nighthawk - 120 fixed-frequency superconducting qubits - square lattice with 218 next-generation tunable couplers - supports circuits with over 5,000 two-qubit gates - median coherence time (T1) of ~350 µs - enables circuits with 30% greater complexity compared to Heron - improving accuracy by 24% and supporting real-time error decoding Rigetti: - 108-qubit Cepheus-1-108Q system - 99.5% median two-qubit gate fidelity - 50-70ns gate speed - composed of twelve 9-qubit chiplets, utilizing Rigetti's proprietary modular chip technology. Its interesting to see this advancement in quantum computing tech, but man IBM is in a very strong position. submitted by /u/JonOwn1805 [link] [comments]
