How fast will a quantum computer be able to calculate? While fully functional versions of these long-sought technological marvels have yet to be built, one theorist at the National Institute of Standards and Technology (NIST) has shown that, if they can be realized, there may be fewer limits to their speed than previously put forth.
The findings—described as a “thought experiment” by NIST’s Stephen Jordan—are about a different aspect of quantum computing speed than another group of NIST researchers explored about two years ago. While the previous findings were concerned with how fast information can travel between two switches in a computer’s processor, Jordan’s new paper deals with how quickly those switches can flip from one state to another.
