There are some obvious big picture issues that stand between us and useful quantum computing. Issues like whether we can make ...

Few people have invented an algorithm with the potential to spark a worldwide crisis, so why is quantum computing pioneer ...

When checking that solutions to certain problems are correct, it turns out, you can’t get around the inherent complexity of ...

Two brothers in Singapore have built a data-encryption company on pure mathematics, betting that a problem no algorithm can ...

Quantinuum lost nearly $200 million last year, saw revenue drop the first quarter of 2026, and says its technology may never work–yet investors are clamoring to buy the stock. The quantum-computer ...

Toronto-based Xanadu Quantum Technologies published a new algorithmic optimization on May 21 that halves the Toffoli gate count inside Quantum Read-Only Memory (QROM) subroutines — the single most ...
