8 Best Quantum Computing Stocks to Invest in According to Hedge Funds.
On May 21, 2026, Xanadu Quantum Technologies Limited (NASDAQ:XNDU) said it had achieved an algorithmic breakthrough in quantum read-only memory by reducing costly quantum operations by approximately half. It also addresses a key bottleneck in the hardware. The company said QROM had not seen any significant progress for seven years, and that its new approach reduces resource requirements for advanced applications.
The corporation said the upgrade halves the number of Toffoli gates among the most computationally intensive operations. It also replaces qubit “swapping” with a more efficient “copy” method and eliminates unnecessary data download steps between QROM sequences. These are two changes with one result: drastically reducing costs.
