A Canadian quantum computing start-up claims its new qubit will enable much smaller and cheaper error-free quantum computers. But getting there will be a steep challenge. To correct its own errors, a ...

Researchers unveiled a new technique that validates quantum computer results—especially those from GBS devices—in minutes ...

Quantum computing is drawing renewed attention owing to a recent advance from Google and talk of the U.S. government taking stakes in companies working on the technology. But the industry has a way to ...

Paris-based quantum computing startup Alice & Bob has announced a stunning breakthrough in quantum computing: its qubits can now resist bit-flip errors for more than an hour. That’s four times longer ...

As the industrial sector accelerates toward innovation, the pressure to do so sustainably and cost-effectively has never been greater. From energy-intensive artificial intelligence workloads to ...

In recent weeks, Rigetti Computing has reported widening quarterly losses, softer revenue and sizeable insider selling, even as it continues to invest heavily in developing larger multi‑chip quantum ...

Investing in quantum computing has brought some unusual challenges. Its quantum bits, called qubits, can store any value between zero and one. This factor makes quantum computers exponentially faster ...

IonQ and IBM are among those building quantum computers -- a new frontier. Since it went public in 2021, IonQ has approximately doubled its sales each year. IBM's established businesses allow it to ...
