How will quantum computing change the world?

The advent of quantum computing is expected to usher in a new era of exponential progress across industries. As these powerful machines harness the strange properties of quantum mechanics to rapidly solve complex problems, many experts predict they will transform everything from drug discovery to climate modeling within the next decade.

Overcoming limits of classical computing

Classical computers rely on bits with binary values of 0 or 1 to perform calculations. In contrast, quantum bits (qubits) can represent 0 and 1 simultaneously through a phenomenon called superposition. By leveraging superposition and other quantum effects, quantum computers can process exponentially more information than regular bits.

While a typical computer would need to check solutions oneby one, a quantum computer can check many solutions at once. This allows quantum machines to solve certain problems that are practically impossible for classical systems in a realistic timeframe.

Prime factorization

One application that demonstrates quantum computing’s exponential speedups is prime factorization finding the prime number factors of an integer. This mathematical task underpins the security of widely used encryption schemes like RSA.

By exploiting superposition, quantum computers can factor extremely large numbers orders of magnitude faster than normal machines. In some demonstrations, quantum systems have factored numbers over 1000 digits long nearly instantly. Such capabilities threaten to break RSA encryption in the future.


Many challenges like finding the best delivery route or optimizing a supply chain can be framed as optimization problems. These problems often contain so many potential solutions that classical systems struggle to find the optimal one.

Quantum annealing computers from companies like D-Wave apply quantum effects to effectively navigate huge solution spaces and locate high quality solutions for optimization tasks. Early applications in finance, aerospace, and more demonstrate quantum speedups for certain optimization problems.

Machine learning

Quantum computing also promises to advance machine learning a key technology powering innovations from self driving cars to predictive healthcare. Quantum machine learning leverages quantum properties to speed up training on complex datasets or even detect patterns classical algorithms cannot.

For instance, quantum versions of support vector machines, neural networks, and recommendation systems have exhibited beyond classical performance for some data analysis tasks. As quantum processors scale up, such quantum machine learning methods are expected to surpass classical techniques.

Industries to be disrupted

The exponential problem solving power unlocked by quantum computers has the potential to disrupt a wide range of industries that rely on processing huge datasets or complex simulations.

Financial services

Banks, insurance firms, and other financial companies analyze massive amounts of data to model risk, detect fraud, optimize investments, and more. By applying quantum machine learning and optimization, financial experts anticipate significantly more accurate quantitative analysis to inform better decisions.

Early experiments in stock market predictions and transactions demonstrate quantum computing’s potential to transform finance. Quantum simulations of market conditions may also facilitate stress testing for future economic crises.


Pharmaceutical researchers must isolate useful drug compounds from endless molecular configuration possibilities. Quantum computing can greatly accelerate the simulation of chemical interactions to determine a molecule’s properties and suitability as medication.

Experts predict quantum computing could shrink the typical 10-15 year drug discovery process to just 2-5 years. This would enable faster delivery of life changing medicines while reducing development costs.


From traffic flow to vehicle design, quantum computers will help overcome complex transportation challenges. Quantum machine learning applied to vast transportation datasets can uncover efficiencies for infrastructure planning or shipping logistics. Quantum optimization algorithms can also discover ingenious solutions for improving electric vehicle batteries.

Ultimately, quantum powered intelligent transportation systems are expected to revolutionize how we and goods travel between destinations. The gains in efficiency and sustainability could be immense.

In 2019, Google officially achieved quantum supremacy on a randomly sampling problem with its 53-qubit Sycamore processor. Since then, rapid advances in quantum hardware, software, and hybrid algorithms integrating quantum and classical systems have brought the quantum revolution even closer to reality.

Maturing hardware

On the hardware front, quantum startups and tech giants are developing increasingly advanced quantum chips with more qubits and greater stability. IBM just unveiled its 433-qubit Osprey processor while competitors like IonQ and Quantinuum recently demonstrated quantum processors at 500+ qubits.

As quantum volume a hardware performance metric continues rising exponentially like this Moore’s Law graph, experts believe processors will soon reach the complexity required for quantum advantage on valuable problems.

Cloud access expanding

Accessing quantum computers over the cloud is also expanding, enabling more developers, researchers, and companies to experiment. IBM, Amazon, Microsoft, and startup Rigetti all offer cloud quantum computing services as well as open source tools like Qiskit and Amazon Braket to build quantum algorithms.

With quantum programming democratized, problem solving breakthroughs are emerging across disciplines through cloud quantum hackathons and collaborations connecting domain experts with quantum programmers.

Hybrid algorithms

Furthermore, hybrid quantum classical algorithms that offload parts of a workflow to each type of system are demonstrating substantial speedups versus classical techniques alone and highlighting practical paths to quantum advantage.

For example, Goldman Sachs and IBM recently developed a hybrid algorithm for options pricing that runs exponentially faster than classical methods. Such demonstrations underline how quantum will soon become critical infrastructure interwoven with classical computing.

Quantum computing workforce booming

The surging quantum industry is also stimulating significant job growth, as quantum hardware and software companies scale up. Large tech employers like Google, Microsoft, Intel, and IBM all have major quantum research groups and are hiring more quantum physicists, developers, and engineers each year.
