Quantum computing technology is promising to transform drug discovery, materials science, financial modeling, cybersecurity, and more.
Given its various use cases, McKinsey estimates the quantum computing market could reach between $43 billion and $71 billion by 2035.
That opportunity has attracted enormous attention to pure-play quantum developers such as Rigetti Computing (RGTI -0.78%).
Where could Rigetti stock be in 2031?
While the math shows Rigetti's stock could double, both scenarios require exceptional execution and broader adoption of quantum computing within a relatively tight time frame.

Their findings, published in Nature Physics, also revealed a sharp transition between chaotic and controlled quantum behavior.
This approach, known as quantum error correction, forms the foundation of fault-tolerant quantum computing.
IBM researcher Maika Takita said the experiment coordinated quantum operations, measurements, and resets thousands of times across a large system.
The demonstration does not establish a fully fault-tolerant quantum computer.
However, it shows that present-day hardware can repeatedly intervene in a quantum system while operations continue, bringing scalable quantum computing closer to a central engineering goal.

The advance is a critical step toward building larger, more reliable quantum computers.
Today’s quantum computers operate according to the unusual rules governing atoms and other extremely small particles.
The experiment is among the largest demonstrations to date of real-time quantum feedback control, a capability considered essential for future quantum computers that will be fault tolerant.
Scaling quantum computers will require them to identify and correct errors while they are working, a capability known as error correction, which will allow for the construction of a fault-tolerant quantum computer.
A fault-tolerant quantum computer is a quantum computer that can keep computing correctly even though its individual quantum bits are constantly making small mistakes.

WASHINGTON - The Department of Defense (DoD) is launching approximately $350 million in quantum-computing initiatives intended to identify national-security applications, validate prospective utility-scale quantum computers, and strengthen the U.S. quantum-computing industrial base.
DARPA advanced four additional quantum-computing companies to Stage C of QBI, the initiative's final evaluation phase.
Related: DARPA funds MagLev Aero propulsion demonstration for drones Quantum computing efforts The four companies join Microsoft and PsiQuantum, which previously advanced to Stage C through the Underexplored Systems for Utility-Scale Quantum Computing pilot program that preceded QBI.
The initiative is not intended to select a single winning technology, but rather to assess the technical viability of multiple approaches to utility-scale quantum computing.
The DoD also plans to identify mission-relevant quantum computing applications in chemistry, materials science, and physics.

The US Department of War has announced new initiatives and programmatic updates totaling approximately USD 350 million to advance US quantum computing capabilities that support national security.
“Dominance in quantum information science is a critical priority for both President Trump and the Department of War,” said Emil Michael, Under Secretary of War for Research and Engineering (R&E).
R&E will direct greater attention across the Department of War’s innovation ecosystem toward identifying mission-relevant applications of quantum computing, particularly as sufficiently capable quantum computers become available.
This new effort will build on existing Department of War programs and complement related national initiatives led by the Department of Energy (DOE), particularly its recently announced Quantum Genesis Priority Applications and the Quantum Genesis Q Competition, as well as initiatives led by the National Science Foundation (NSF) and the National Aeronautics and Space Administration (NASA).
Defense Advanced Research Projects Agency (DARPA) is also advancing the technical validation needed to determine whether prospective quantum computing systems can deliver utility at scale.

Dive Brief: Healthcare organizations aren’t prepared for cybersecurity threats from quantum computing — an emerging technology that could break the encryption protecting patient data — according to a new report.
The researchers also analyzed more than 5,500 internet-facing healthcare systems like patient portals and certain application programming interfaces.
“The primary threat is not that hackers will suddenly use quantum computers to attack hospitals tomorrow,” said Daniel Trivellato, vice president of operational technology, healthcare and cyber risk solutions at Forescout.
Healthcare data breaches cost organizations about $6.64 million on average, according to IBM.
“For a CEO or CFO, the choice is not between spending money now or spending nothing until quantum computers arrive,” Trivellato said.

In brief Europol, the European Union's law enforcement agency, published two reports Wednesday urging the crypto industry and policymakers to prepare now for quantum computing threats.
The first, Quantum Computing and Cryptocurrencies, produced by Europol's European Cybercrime Centre, identifies cryptocurrency wallets as "the primary point of exposure to quantum threats."
Wallets rely on a pair of keys: a private key that authorizes transactions and a public key the network uses to verify them.
"Cryptocurrencies will not collapse due to quantum computing," the report concludes, while recommending “proactive defence” to ensure their long-term security.
It describes a "just-in-time" attack, in which a quantum computer derives a private key during the short window between a transaction exposing its public key and that transaction being confirmed.
