Editor’s Note: This is a four-part series of DIs proposing improvements in the performance of a “traditional” PWM—one whose output is a duty cycle-variable rectangular pulse which requires filtering ...

There’s a strong consensus that tackling most useful problems with a quantum computer will require that the computer be capable of error correction. There is ...

For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...
