In 1965, he purchased the assets of the recently defunct Pittsburgh Courier and started the New Pittsburgh Courier He had previously established the Michigan Chronicle in Detroit in 1936, and turned the Chicago paper's Memphis bureau into the Tri-State Defender weekly newspaper in 1951. Sengstacke also built his newspaper into a chain. It published as a daily until 2003, when new owners converted the Defender back to a weekly. On February 6, 1956, the Defender became a daily newspaper and changed its name to the Chicago Daily Defender, the nation's second black daily newspaper (after the Atlanta Daily World, founded in 1928). Sengstacke, who became publisher in 1940, was a founder of the National Negro Publishers Association, later renamed the National Newspaper Publishers Association (NNPA), which now has 200 member black newspapers. Like other giants of the contemporary black press, the Defender enjoyed substantial circulation across the nation. Sengstacke also used the Defender as a means to grow the community, writing stories about Northern city life that enticed African-American residents of the Southern United States to move to Chicago, a phenomenon that came to be known as the Great Migration. The Defender served the growing African-American community of Chicago, which was often ignored by the mainstream newspapers of the day. Robert Sengstacke Abbott founded the Chicago Defender in 1905, billing it the "World's Greatest Weekly".

If so, should we expect to see any difference between the qasm results and the results from real quantum devices? (I could not print out the noise information, so I'm a bit confused which error values we are using.) Thanks!

However, I wonder as I give this information to qasm simulator and run the experiments, am I using the real-time error rate as the noise model? result = execute(circ, Aer.get_backend('qasm_simulator'), So I could see the source of errors as well as qubit connections.
