IBM researchers have finally proven in a real-world experiment that quantum computers are superior to classical devices – although for now, only at a miniature scale. 

Big Blue’s quantum team set out to discover if today’s quantum devices, despite their limitations, could be used to complete a task that cannot be done on a classical system.  

Since quantum computing is still in its infancy, the researchers leveled the playing field between the two methods by designing a microscopic experiment with limited space – that is, limited amount of available memory.
