Superconducting Qubits

In a quantum race where no one yet knows which kind of qubit will win, one line is out front — qubits made from superconducting electrical circuits, chilled to ~15 millikelvin (colder than deep space) and driven by microwave pulses. It's the path IBM and Google chose to bet on, because it has the "fastest gates" and can be made on a chip production line. This lesson digs into how it works, why it's ahead, and what price it pays.

IBM Wins $1 Billion Commerce Award as Anderon Quantum Foundry Begins Production

IBM secured a finalized $1 billion award from the Commerce Department for its Anderon subsidiary, which is now operating a 300-millimeter quantum-wafer foundry in Albany, New York. IBM is committing another $1 billion of its own capital to the project, bringing newly disclosed commitments to $2 billion, with the federal government covering half of that total. Initial wafers have already entered production at the facility, which is designed to manufacture technology for superconducting qubits, input-output signaling and readout components, with additional quantum architectures expected to follow. The funding split reduces how much IBM must fund itself while potentially turning Anderon into manufacturing infrastructure for outside quantum-chip designers. IBM shares gained approximately 0.2% to $237.87 Thursday morning, about 2% below the $242.72 GF Value estimate, though IBM has not yet disclosed customers, purchase commitments, wafer volumes or expected Anderon revenue.

IBM's Anderon Finalizes $1 Billion CHIPS Act Quantum Foundry Award

Anderon, an IBM subsidiary, finalized a $1 billion research-and-development award from the U.S. Department of Commerce on Wednesday under the 2022 CHIPS and Science Act. The funding will support Anderon's efforts to advance quantum wafer manufacturing at its facility in Albany, New York, where a 300-millimeter quantum wafer foundry serves customers across the quantum industry. IBM has put up $1 billion of its own money alongside the federal award, and production is underway with quantum wafers already in process. The Anderon award is part of a broader $2 billion package distributed across nine quantum computing companies under the CHIPS and Science Act, with GlobalFoundries in line for $375 million and D-Wave Quantum, Rigetti Computing, and Infleqtion each expected to receive $100 million; each of the nine firms will give the federal government a minority ownership stake in exchange for the funding. The finalization follows a letter of intent between IBM and the Commerce Department announced in May, and last week Rigetti Computing, D-Wave Quantum, and Quantinuum each finalized $100 million deals with the department. IBM stock fell 3.3% on Wednesday and has declined nearly 19% this year.

NEC Halts Development of Quantum Computer Hardware

NEC has decided to halt the development of actual quantum computer hardware, which processes vast amounts of calculations at high speed, by the end of March. The company achieved the world's first superconducting qubit in 1999, establishing itself as a pioneer in the superconducting approach later adopted by Google and IBM. However, due to many challenges such as the lack of a dominant technology for practical use, continuing hardware development was deemed not cost-effective. NEC will continue its research and development leveraging quantum mechanics. In Japan, Fujitsu is currently leading research, and in 2025, it developed one of the world's largest quantum computers in collaboration with RIKEN.

IBM and Qedma Achieve Quantum Advantage in Materials Physics Simulation

IBM and Qedma Quantum Computing have demonstrated quantum advantage by using error-mitigated quantum computation to model physics beyond the reach of classical supercomputers. The collaboration combined Qedma's QESEM error reduction software with IBM's 74-qubit Quantum Heron processor to resolve complex, long-lived dynamics in a two-dimensional Floquet Ising model, a system used to study magnetic properties under rhythmic driving. Classical simulations, including those run on RIKEN's Fugaku supercomputer and by BlueQubit, failed to provide consistent answers at the scale reached by the quantum experiments. The results were independently validated across platforms, including Quantinuum's trapped-ion systems, confirming the observed physics originated from the simulated quantum system. This marks the first time quantum advantage has been achieved with commercially available hardware and software, establishing error-mitigated quantum computers as trusted scientific instruments for exploring advanced materials applications.

Nvidia, Microsoft, and Alphabet vie to be the top pick-and-shovel play in quantum computing

Nvidia, Microsoft, and Alphabet are positioning themselves as upstream providers to the quantum computing industry, which McKinsey estimates could grow from $1 billion today to $4.4 billion by 2028. Nvidia does not build quantum chips but offers CUDA-Q software and the NVQLink interconnect, already adopted by 17 quantum builders and nine national labs, and stands to benefit from selling classical computing power needed for error correction regardless of qubit type. Microsoft runs the Azure Quantum marketplace, reselling access to hardware from partners like Quantinuum and IonQ, while developing its own Majorana 2 topological chip, which it claims is 1,000 times more reliable than its predecessor. Alphabet’s Google Quantum AI builds superconducting chips such as the 105-qubit Willow processor, which demonstrated exponential error reduction and a computational advantage, and may eventually sell access through Google Cloud. Among the three, Nvidia is identified as the best pick-and-shovel play due to its direct, qubit-agnostic exposure, with Microsoft a close second for its low-risk marketplace model.

Kalshi traders see low odds for OpenAI government stake deal this year

Kalshi contract traders remain highly skeptical that a deal will materialize before the end of the year for the U.S. government to take a stake in OpenAI or Anthropic, despite recent reports that OpenAI proposed granting a 5% stake to the Trump administration. Traders see odds of less than 30% for such a stake, according to a CNBC report. In contrast, odds are well over 60% that the government could take a stake this year in quantum computing companies Rigetti Computing or D-Wave Quantum, as well as in semiconductor manufacturer GlobalFoundries.

D-Wave and Rigetti Compete for Quantum Leadership in H2 2026

D-Wave Quantum and Rigetti Computing are vying for investor attention as the second half of 2026 begins, with both stocks down year to date amid cautious sentiment. D-Wave enters the period with record bookings and a strong enterprise pipeline, while its acquisition of Quantum Circuits expands its technology into gate-model computing. Rigetti launched general availability of its 108-qubit Cepheus-1 system and reported nearly 199% year-over-year revenue growth, reaffirming its goal of achieving quantum advantage in roughly three years. Analysts have turned cautious on D-Wave's near-term earnings, while Rigetti has seen smaller downward estimate revisions. Zacks Investment Research rates D-Wave a Hold and Rigetti a Sell, favoring D-Wave's commercial traction in the near term.

D-Wave Quantum Gains Investor Focus Amid Microsoft's Majorana Controversy

A scientific dispute over Microsoft's quantum-computing research has shifted investor attention toward D-Wave Quantum, which is showing strong commercial traction. Researchers published a critique in Nature questioning whether Microsoft's experimental results sufficiently demonstrate the Majorana particles needed for its topological-qubit architecture, though Microsoft disputes the criticism. The controversy highlights a broader industry debate over scientific validation versus long-term platform potential. D-Wave reported first-quarter 2026 bookings of $33.4 million, a nearly twentyfold increase from the prior-year period, and has expanded into gate-model quantum computing through its acquisition of Quantum Circuits. Analysts have raised their full-year 2026 estimates, with the Zacks Consensus Estimate for D-Wave's loss narrowing from 31 cents to 25 cents per share over the past 90 days.

Investors Begin Separating Quantum Computing Winners From Losers

Investors are increasingly distinguishing between quantum computing companies based on commercial progress rather than scientific promise, with IonQ gaining ground while D-Wave, Rigetti, and Quantum Computing Inc. declined over the past six months. IonQ has generated positive returns, whereas D-Wave Quantum, Rigetti Computing, and Quantum Computing Inc. have all moved lower despite ongoing technological announcements. The shift was partly catalyzed by Nvidia CEO Jensen Huang's January 2025 warning that practical quantum computing may be decades away, though Nvidia itself deepened quantum investments through CUDA-Q and hybrid computing initiatives. Analysts note that major infrastructure players like Microsoft, Amazon, Alphabet, IBM, and Nvidia may capture more quantum value than pure-play hardware companies by profiting regardless of which architecture wins. The market is now rewarding evidence of revenue growth, customer adoption, and a credible path to commercialization.
