Quantum computing uses quantum properties of individual atoms, enabling parallel calculation of millions of scenarios simultaneously.
This makes it fundamentally different and vastly more powerful for certain problems than classical binary computing.

Quantum computing has long been technology’s white whale. But in recent months, new developments suggest practical applications for this elusive technology could finally be within reach. “Quantum has been five to ten years away from fruition for many, many decades,” says McKinsey Partner Michael Bogobowicz. “Now it feels three to five years away.” In this episode of The McKinsey Podcast, Bogobowicz joins McKinsey Global Editorial Director Lucia Rahilly to discuss how quantum differs from conventional computing, what its potential use cases are likely to be, and how to prepare for the highs and lows of a world that could move exponentially faster than it does today.
In our second segment we ask, what’s the most important factor in having a successful transformation? McKinsey Senior Partner Michael Bucy says it’s the CEO.
