...would allow for travel at well over one thousand miles per hour.

This resembles an April Fool joke.

Military A/C already use similar technology to reduce the compressor inlet speed to below supersonic. The engine won't run with  supersonic air going in the inlet.

Also, the sonic boom comes from more than just the parts associated with the intake. A sonic boom can be generated by any object traveling faster than the speed of sound, whether it has an engine, or not. The most prominent example is a bullet.

It does seem to be a little contradictory. The speed of sound is a function of air temperature ( Temperature = pressure) If you have too much air into your inlet, you are flying too low, and a sonic boom at low altitude is the thing that really irks the neighbors. If you want to go past Mach X at high air density, it seems like it would be time to turn to a RAM Jet, rather than a Turbo jet. If you want to fly really fast and not go boom, fly where the air is coldest, or cold enough for you to remain pre-mach. In space, no one can hear you scream...Maybe the Science writer misunderstood the purpose of turbulent airflow into the conventional jet engine.

"The path of the righteous man is beset on all sides by the iniquities of the selfish and the tyranny of evil men. Blessed is he, who in the name of charity and good will, shepherds the weak through the valley of darkness, for he is truly his brother's keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who would attempt to poison and destroy my brothers. And you will know my name is the Lord when I lay my vengeance upon thee."
