Quantum Elements has achieved the highest fidelity for entangled logical qubits on a superconducting quantum computer. The Los Angeles startup utilized its AI-powered quantum digital twin platform to simulate both the intended functioning of a quantum circuit and the impact of real-world hardware noise.

This method, termed logical dynamical decoupling, entails transitioning qubits among various states to suppress errors. The findings were documented in a peer-reviewed paper published in Nature Communications in February.
