D-Wave Quantum has emerged as a leader in quantum computing, analysts say, and Wall Street is throwing its support behind the company in a raft of research notes following its latest earnings report.

D-Wave is the latest quantum computing company to say it has achieved “quantum supremacy,” better known as the ability to solve a problem with a quantum computer that can’t be done with a traditional computer.

The company says it has solved the first problem of scientific relevance with a quantum processor faster than could be done with classical computers—but others disagree

D-Wave Quantum shares popped Wednesday, along with other quantum computing stocks, after the company claimed to achieve a breakthrough.

Shares of some quantum computing companies rallied on Thursday, adding to gains from the previous session and bucking the broader market's trend after D-Wave Quantum forecast stronger-than-expected quarterly revenue.
