China is racing to harden its quantum ambitions on two fronts at once, pairing more powerful quantum processors with new ...

Evolution paths of the single control qubit on the Bloch sphere in the hybrid approach to Grover’s algorithm. Quantum computers are built of elementary operations called quantum gates that are similar ...

In a major step toward practical quantum computers, Princeton engineers have built a superconducting qubit that lasts three times longer than today’s best versions. “The real challenge, the thing that ...

Diraq has shown that its silicon-based quantum chips can maintain world-class accuracy even when mass-produced in semiconductor foundries. Achieving over 99% fidelity in two-qubit operations, the ...

Quantum computing is getting there. After years of slow but steady development to create a useful quantum computer that can outperform classical machines, we’re still squarely in the “noisy ...
