The boundaries that classical computing has set are now becoming very obvious, with every second starting to count in this age. Complex problems, from optimizing financial portfolios to ensuring cybersecurity, advancing healthcare, and pushing the frontiers of artificial intelligence, beleaguer industries around the globe. The requirement for more powerful computational tools is not a question of convenience; it is turning out to be a fact of innovation and competitiveness. Enter quantum computingâ€”a revolutionary technology that promises to solve problems that classical computers struggle or can’t find solutions for.

## Classical Computing Can’t Keep Up

The problems industries have faced have changed over the years, increasing in complexity and full of data. On the other hand, classical computers are powerful and based on binary bits to process information but are limited in dealing with the huge amounts of data and complex calculations required by modern industries.

For example, in finance, classical computers will only approximate solutions to optimization problems and hence leave some profit on the ground. The computational power required for modeling molecular interactions in healthcare, for instance, drives drug discovery. A significant fraction of advanced models trained within AI take weeks or months to train and serve customers, slowing innovation. In the context of cybersecurity, data breaches, and cyber-attacks are growing way faster than the security measures being developed to counter these attacks.

These limitations are more than annoyingâ€”they’re holding up development across multiple industries.

## The Stakes are Higher Than Ever

Think of the billions of dollars in lost profitability if your models are not optimal for your financial system. Or else, think about the many lives that would have otherwise gone if higher rates of speed and accuracy in drug discovery had been practicable. Think of the risks associated with not having good cybersecurity measures in a cyberattack-run world. And what about AI? By the time those breakthroughs are integrated into commercial products, slow train times are missing those innovations that could change industries from health to customer service.

The stakes don’t get much higher. It’s not just a matter of staying competitive-industries-NEED more computational firepower if they are going to drive the next wave of innovation and secure their future in an increasingly digital world.

## The Solution: Quantum Computing
