D-Wave Shifting to Gate Model Quantum Computer

D-Wave Systems revealed their next-generation quantum computing platforms will include both annealing and gate-model quantum computers. This is a significant shift because they were the pioneers in quantum computing but used something like an analog computer, called an annealer. D-Wave is responding to major competition with billion-dollar valuations and hundreds of millions in funding. IonQ …
