Lyft has been a public company for just over a week now, during which its market capitalization has fluctuated between $30 billion (the high, just after the stock opened for trading on March 29) and $22 billion (the low, on Tuesday).

The big picture: Stock market investors can be forgiven for being unclear about how much Lyft is really worth. Lyft doesn't break out how much it's spending on discounts and incentives, for instance, and it doesn't disclose key metrics such as acquisition costs or churn rates, either for passengers or for drivers.

The enormous promise of quantum computing has lured big early investments from finance, aerospace, defense, and other tech-soaked industries. But an unexpected player is neck-and-neck with these front-runners: carmakers.

Big auto companies are tinkering with quantum computers in hopes they can solve problems too hefty for today's machines, from cooking up bigger batteries to designing lighter vehicles. And as they experiment, a host of other companies are lingering on the sidelines, watching for the right moment to jump in.
