Yesterday was World Quantum Day, a day dedicated to raising awareness of the physics that powers the quantum computers of tomorrow.

But awareness of quantum technology wasn’t the only thing that was rising. So, too, were the stock prices of America’s four major quantum computing companies: D-Wave, IonQ, Rigetti, and Quantum Computing Inc.

And today, the stock prices of those four companies are even higher. Here’s why.

Quantum computing stocks soar

If you’re an investor in any of the so-called Quantum Four quantum computing companies, yesterday was a good day. All four major American quantum computing companies saw double-digit gains yesterday, including:

D-Wave Quantum Inc. (NYSE: QBTS): up 15.8% to $16.97

IonQ, Inc. (NYSE: IONQ): up 20.1% to $35.76

Quantum Computing Inc. (Nasdaq: QUBT): up 11.5% to $8.11

Rigetti Computing, Inc. (Nasdaq: RGTI): up 11.5% to $16.87

Those are significant one-day gains. But they haven’t stopped there. As of the time of this writing, in premarket trading today, all four quantum stocks are on the rise yet again.

Currently,  D-Wave is up another 8%, IonQ is up another 4.6%, Quantum Computing Inc. is up another 3.7%, and Rigetti is up another 5%.

But the question is: Why?
