Errors in quantum computers are an obstacle for their widespread use. But a team of scientists say that, by using an antimony atom and the Schrödinger's Cat thought experiment, they could have found a way to stop them.

Google's news about a technological advance in quantum computing created a lot of FUD about its impact on Bitcoin. While Google's new Willow chip is still years, if not decades, away from impacting Bitcoin, it raises a legitimate question: What will quantum computing do to Bitcoin? Short answer: Bitcoin will adapt.

MIT researchers have achieved a world-record single-qubit fidelity of 99.998% using fluxonium, a superconducting qubit.

Scott Bessent, President-elect Donald Trump’s choice for Treasury secretary, said Jan. 16 that the U.S. should institute a “very rigorous screening process” to ensure its outbound investment does not help China catch up to the U.S. in such key technology areas as artificial intelligence, computing chips, quantum computing and surveillance.

Stocks of quantum computing companies jumped Wednesday after Microsoft declared this as “the year to become quantum-ready,” adding “we are at the advent of the reliable quantum computing era.” Shares of Rigetti Computing and D-Wave Quantum were both up more than 22 percent.

Quantum computing stocks were red-hot recently, but Jensen Huang just offered optimistic investors a reality check.

While quantum computing offers long-term transformative promise, robotics provides clear, near-term returns, creating complementary paths for investors balancing vision with immediacy.
