The U.S. added an estimated 178,000 jobs in March, rebounding from unexpectedly large job losses in February, according to data released Friday morning. March’s gains were about three times what economists expected, and the unemployment rate edged down to 4.3%. Why the March jobs report matters Market watchers generally viewed…
While artificial intelligence (AI) investing may be at the front of the market's mind, another emerging tech trend is quantum computing, which some investors view as having the potential to reshape multiple computing industries, including AI. One widely discussed company in this space is Rigetti Computing (RGTI +5.11%). The key question is whether Rigetti’s progress is sufficient to make it a compelling quantum computing stock.
A central concern for quantum computing remains accuracy. The technology is not yet accurate enough to be commercially viable, and improving error rates is the main hurdle for companies in the sector.
Rigetti recently announced it achieved up to a 99.9% two-qubit gate fidelity. In practical terms, that implies that when a calculation passes through two processing gates, there is a one in 1,000 chance the process produces an error.
The article notes that even small error rates can matter because quantum systems must perform many operations quickly. It frames the issue as a problem of maintaining correctness across large numbers of processes.
Beyond headline fidelity, the article highlights another issue: as the number of qubits in a system increases, accuracy declines. It states that Rigetti’s largest 108-qubit system has a 99% two-qubit gate accuracy.
According to the article, declining accuracy as computing power increases is not a favorable sign for Rigetti’s path to commercial viability, and it suggests the company still has substantial work to do relative to competition.
The article also points to IonQ (IONQ +5.43%) as another quantum computing stock. It says IonQ holds a world record for two-qubit gate fidelity at 99.99%. The performance is described as having been achieved in IonQ’s R&D lab, with the article stating it is expected to be applied to IonQ’s 256-qubit system in 2026.
In the comparison presented, IonQ is described as moving toward a system with more than double the computing capacity versus Rigetti, alongside a much higher accuracy level.
Based on the accuracy figures and the comparison to IonQ, the article concludes that Rigetti’s viability is questionable. It argues that while Rigetti’s accuracy improvements are important, it is still behind peers in the quantum computing race and would require a major breakthrough to catch up.
The article ultimately states that it does not consider Rigetti Computing worth an investment, citing IonQ as a preferable alternative.
