Quantum computing has suddenly become a buzzword on Wall Street. Ever since Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL) reported that it hit a new milestone with Willow, its new quantum chip, quantum stocks have been soaring. The announcement sparked a rally in Alphabet stock and sent shares of small-cap pure-play quantum computing stocks like D-Wave Quantum (NYSE: QBTS), Quantum Computing (NASDAQ: QUBT), Rigetti Computing (NASDAQ: RGTI), and IonQ (NYSE: IONQ) skyrocketing.
