The same stocks rallied earlier this week after Microsoft unveiled an initiative meant to familiarize business leaders with quantum systems.

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.

Quantum computing is taking off, but how long will it take, and which stocks should you consider? Two leaders in the space stand out as great investments today.
