Microsoft's remarks helped drive shares of Rigetti Computing more than 16% higher in premarket trading Wewdnesday, while D-Wave quantum surged 26%. IonQ added nearly 10%, while the Defiance Quantum and AI ETF added nearly 3%. The rally was also fueled by Nvidia on Tuesday announcing a "Quantum Day" at its GTC Conference in March.

Quantum Computing didn't have any news of its own to report, but the company is even smaller than D-Wave, with less than $1 million in revenue over the last four quarters. Its stock has soared even higher than D-Wave's over the last year, a disconnect that could lead to a continued decline in Quantum Computing's shares.
