New method achieves tenfold increase in quantum coherence time via destructive interference of correlated noise

by

A Bloch sphere of a qubit subjected to cross-correlated noise (blue and red). The method destructively disrupts this noise, resulting in superior performance. Credit: Physical assessment letters (2024). DOI: 10.1103/PhysRevLett.132.223601 Researchers have developed a new method to significantly improve the performance of quantum technology by using the cross-correlation of two noise sources to extend coherence … Read more
