Hedge fund manager Ken Griffin sold Sandisk (one of the hottest AI stocks) and bought D-Wave Quantum (one of the hottest quantum computing stocks) in the third quarter.
Every winter, many families revive a familiar ritual. Children rush to find a small elf that supposedly watched them overnight and moved before morning. The hunt is part of the excitement. As children grow older, that excitement often turns into doubt, with questions about whether the elf is magic or simply a parental story.
D-Wave Quantum Inc. (NYSE: QBTS) (“D-Wave” or the “Company”), a leader in quantum computing systems, software, and services, and the world’s first commercial supplier of quantum computers, today announced that it has completed its previously announced acquisition of Quantum Circuits Inc. (“Quantum Circuits”), a leading developer of error-corrected superconducting gate-model quantum computing systems. D-Wave expects the acquisition to significantly accelerate the time to a scaled, error-corrected gate-model quantum computer alongside and complementary to its commercial annealing quantum computing systems.
Wall Street's hottest pure-play quantum computing stocks have inadvertently highlighted one of the biggest risks inherent to investing in next-big-thing technologies.
As of mid-January 2026, a seismic shift is occurring in the hallowed halls of Wall Street and the research labs of Silicon Valley. After three years of an unprecedented artificial intelligence bull market that reshaped the global economy, institutional capital is beginning to rotate. The new destination is not just
D-Wave Quantum Inc. (NYSE: QBTS) (“D-Wave”), a leader in quantum computing systems, software, and services, and the world’s first commercial supplier of quantum computers, and Quantum Circuits, Inc. (“Quantum Circuits”), a leading developer of error-corrected superconducting gate-model quantum computing systems, recently announced that the companies have entered into a merger agreement under which D-Wave will acquire Quantum Circuits for a purchase price of $550 million, consisting of $300 million in D-Wave common stock and $250 million in cash. By combining the world’s leading annealing quantum computing company with the world’s leading developer of error-corrected gate-model technology, D-Wave aims to dramatically accelerate the projected time to a scaled, error-corrected gate-model quantum computer alongside and complementary to its commercial annealing quantum systems.
D-Wave Quantum Inc. (NYSE: QBTS) (“D-Wave”), a leader in quantum computing systems, software, and services and the world’s first commercial supplier of quantum computers, recently announced a breakthrough in gate-model quantum computing with the successful demonstration of scalable on-chip cryogenic control of qubits. This industry-first milestone advances the development of commercially viable gate-model quantum computers by significantly reducing the wiring required to control large numbers of qubits without degrading qubit fidelity.
Early cancer detection has long been one of the biggest challenges in modern medicine. Many cancers are only discovered when symptoms appear, and by then, treatment becomes harder and survival rates drop. A newly developed AI-powered sensor system could change this story by making it easier to detect cancer much earlier, even before clear symptoms begin.
