Infleqtion’s Post

Infleqtion researchers and collaborators at the University of Wisconsin-Madison, including Infleqtion Chief Scientist for Quantum Information Professor Mark Saffman, have published new work on improving neutral-atom entangling gate fidelities near Förster resonances. The paper identifies an important mechanism: when atoms are tuned near Förster resonances, the exchange interaction between quantum states can actively suppress gate errors. By incorporating this into gate design, the team demonstrates a path to fidelities exceeding 99.9% - a threshold considered essential for fault-tolerant quantum computing and a meaningful reduction in the overhead required to run reliable logical qubits at scale.
