US Patent Issued to Telefonaktiebolaget LM Ericsson on Sept. 22 for "Quantum approach to generate soft bit information in multi-antenna communication systems" (Swedish, American Inventors)

ALEXANDRIA, Va., Sept. 24 -- United States Patent no. 12,744,563, issued on Sept. 22, was assigned to Telefonaktiebolaget LM Ericsson (publ) (Stockholm).

"Quantum approach to generate soft bit information in multi-antenna communication systems" was invented by Altay Dikme (Stockholm), Sairamesh Nammi (Austin, Texas) and Ahsan Javed Awan (Vallentuna, Sweden).

According to the abstract* released by the U.S. Patent & Trademark Office: "Quantum computing methods are used to generate the soft bit information for decoding by solving a single hard MIMO maximum likelihood detection problem using the quantum computer. Probabilities P(bi=1|y) and P(bi=0|y) are determined from the state distribution that is obtained when executing a quantum circuit ...
