Theoretical discovery opens the door to building quantum computers with significantly reduced resources Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new approach for reducing the errors that riddle today's rudimentary quantum computers. Whereas these machines were previously thought to require millions of qubits to work properly (qubits being the quantum equivalent to 1's and 0's in classical computers), the new results indicate that a fully realized quantum computer could be built with as few as 10,000 to 20,000 qubits. The need for fewer qubits means that quantum computers could, in theory, be operational by the end of the decade. The team proposes a new quantum error-correction architecture that is significantly more efficient than previous approaches. Quantum error correction is a process by which extra, redundant qubits are introduced to correct errors, or faults, enabling the ultimate goal in the field: fault-tolerant quantum computing. The results exploit special properties of quantum computing platforms built out of neutral atoms, which serve as the qubits. Alternative platforms in development include superconducting circuits and trapped ions (ions are charged whereas neutral atoms are not). In a neutral atom system, laser beams known as optical tweezers are used to arrange atoms into qubit arrays. Manuel Endres, a professor of physics at Caltech, and his colleagues recently created the largest qubit array ever assembled, containing 6,100 trapped neutral atoms. "Unlike other quantum computing platforms, neutral atom qubits can be directly connected over large distances," Endres says. "Optical tweezers can shuttle one atom to the other end of the array and directly entangle it with another atom." This dynamic ability to move atoms is key to the researchers' ultra-efficient error-correction scheme, which they describe

TradingKey - There is much speculation surrounding Rigetti(RGTI.US) Computing as it is a high-risk player within the quantum computing space of the tech market, and Rigetti stock has experienced significant price fluctuations repeatedly.
The Analyst Upgrade Fueled the Early Surge in Rigetti Stock The bullish call from Benchmark Analyst David Williams, who boosted the price target of Rigetti's shares from approximately $20 to $50, was responsible for the initial rise in Rigetti stock.
Ultimately, the analyst upgrade created considerable momentum in Rigetti stock price in early trading.
Quantum Computing Has a Long-Term Future Rigetti's stock has had significant ups and downs in value, and that has to do with the unstable quantum computing industry.
Therefore, each quantum computing company, like Rigetti, is developing an entirely new type of computing that has not been completed yet.

However, today’s quantum computers resemble classical computers of the 1950s and 60s: brittle, without error correction, and expensive to operate, but powerful for niche applications.
The first is an execution layer that improves how algorithms are compiled, optimized, mitigated, and run on quantum hardware.
Why quantum advantage is not here yet The pursuit of quantum advantage – the point at which quantum hardware surpasses classical computing in solving certain problems – requires active exploration of both suitable intractable problems and novel quantum algorithm design.
This makes identifying anomalies, such as a fraudulent transaction in vast datasets, more efficient on available quantum hardware.
The benefits of software-enabled quantum utility With the opportunity to experiment broadly with accessible quantum hardware, researchers could further their expertise and understanding of what problems are best suited for quantum computation, leading to more opportunities to achieve quantum advantage in both academic and real-world problems.

Cisco continues to double down on its quantum side hustle, joining up with quantum computing firm Infleqtion to research networked quantum systems.
“The next major breakthrough in quantum will not come from building bigger isolated machines, but from networking systems together,” Ramana Kompella, VP and head of Cisco Research, explained.
“By combining Cisco’s quantum networking leadership with Infleqtion’s quantum platforms, we are developing the communication architecture needed to scale quantum capabilities from standalone devices into resilient, collaborative networks.”
Ultimately, the partnership seeks to pave the way for interconnecting diverse quantum computers, sensors, and related hardware into larger, distributed networks.
“Achieving the broadest applications of quantum computing will require many quantum systems working together," Inflecqtion CTO Pranav Gokhale added.
