Two recent breakthroughs in quantum computing have added excitement to this cutting-edge technology. The first achievement came from Google where a new quantum-algorithm Quantum Echoes, running on Google’s quantum chip Willow (~105 qbits), can achieve result 13,000 times faster than running on the current fastest supercomputer. Crucially, the result is verifiable which means it can be repeated.
The second achievement came from IonQ, a leading quantum company, that demonstrates 99.99% two-qubit gate fidelity - meaning an error rate of less than ~1×10⁻⁴ per two-qubit operation. This fidelity is considered a world record for two-qubit gates and a major step toward fault-tolerant quantum computing. As fidelity improves, fewer errors must be addressed and more complex algorithms can be run. In fact, IonQ’s roadmap projects logical two-qubit gate fidelity of 99.999% by end of 2025.
As more breakthroughs are achieved, quantum computing is moving from theoretical realm to commercial application world. The next few years will be an exciting time as AI and quantum computing converge and enable advanced scientific discoveries.
