The Next Big Computing Revolution Is Coming

Creating revolutionary pharmaceutical drugs, testing new materials for cars, or simulating complex financial markets can take months or even years with the most advanced classical computers.

But quantum computing promises to cut these timeframes to minutes or hours.

Quantum computing has been studied for decades. Recently, it has attracted massive investments from tech giants, startups, and research institutions.

On Wednesday, IBM unveiled its experimental Loon processor and Nighthawk quantum chip, capable of performing more complex computations than previous models. Over the past two years, Google, Microsoft, and other tech companies have also made significant quantum computing announcements.

Experts predict that quantum computing could add $1.3 trillion in value across industries by 2035 (McKinsey & Company). It has potential breakthroughs in cryptography, finance, pharmaceuticals, materials science, and transportation. IBM claims the technology could solve problems in minutes or hours that would take classical computers thousands of years.

Quantum Computing Is Not Just a Faster Computer

Quantum computing isn’t about upgrading current computers. It’s a completely new approach based on quantum physics.

“A fighter jet is not a faster Ferrari because it has wings,” said Sridhar Tayur, professor at Carnegie Mellon University.
“Quantum computing is not just a faster classical computer—it works on entirely different principles.”

What Makes Quantum Computers Unique?

Classical computers use bits, represented as 0s or 1s. Quantum computers use qubits, which can exist in multiple states simultaneously. This property, known as superposition, allows quantum computers to process information exponentially faster.

Think of it as a coin: bits are like a coin landing on heads or tails. Qubits are like a coin spinning, representing both heads and tails at once.

Quantum computers are not meant to replace laptops or smartphones. They are ideal for solving complex, large-scale problems in:

Drug discovery and biotechnology
Cryptography and cybersecurity
Environmental modeling
Financial simulations
Advanced materials and chemical research

Quantum Computing in Real-World Applications

Companies are already testing quantum computing for high-impact applications:

BMW Group and Airbus are partnering with startup Quantinuum to research quantum-enabled fuel cell development.
Accenture Labs, Biogen, and 1QBit collaborate on drug discovery, allowing simulations of molecules larger than classical computers can handle.

“The big hope is that a quantum computer can simulate any chemical or biological experiment you would do in the lab,” said Anand Natarajan, MIT associate professor.

Quantum computing also has cybersecurity implications, as it could break encryption protecting sensitive data.

The Race to Quantum Supremacy

Quantum computing faces major challenges. Qubits are extremely fragile, affected by temperature, light, and vibration.

IBM’s Loon processor aims to build fault-tolerant quantum computers that work even with errors. IBM’s Nighthawk chip can run more complex quantum gates, the building blocks for quantum algorithms.

Other companies in the race include

Microsoft: Majorana 1 chip creates a new state of matter for more stable qubits.
Google: Willow chip reduces errors and can perform in five minutes what a classical computer would take 10 septillion years to solve.

Despite advances, fully fault-tolerant quantum computers may still be 10–20 years away, according to experts. McKinsey reports that 72% of executives and academics expect them by 2035, while IBM hopes to achieve it by the end of the decade.

Why Quantum Computing Matters

Quantum computers could revolutionize industries by offering refined computational tools that drastically outperform classical systems.

“Right now, we are trying to do brain surgery using a spoon and a fork. Quantum computing gives us the refined tools we need,” said Tayur.

With faster simulations, improved cryptography, and complex problem-solving, quantum computing could change how we approach science, healthcare, finance, and technology.
