Quantum Elements Achieves Record Fidelity for Entangled Qubits Using AI Digital Twin
Quantum Elements, a Los Angeles startup, has achieved record fidelity for entangled logical qubits on a superconducting quantum computer using its AI-powered digital twin platform. This platform simulates real-world hardware noise alongside the intended quantum circuit behavior. The technique, known as logical dynamical decoupling, involves shifting qubits between different states. A peer-reviewed paper detailing the findings was published in Nature Communications in February.

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.
