The Rise of Quantum Computing: Implications for the Future

Aug 27, 2024

Quantum computing is a new technology which is based on quantum mechanics and helps to process information in a more effective way. Quantum computers are finally showing capabilities that no classical computer can offer after several decades of research. This means that we are likely to get to a position where quantum computers will start to disrupt core business sectors.

But what does this all mean for the future of quantum computing? But where are we now with quantum computing, and where might it be in the future, and what might it mean for us?

Quantum computing today 

Although at a relatively early stage, quantum computing has recently transitioned from the lab environment to application. In 2019, Google managed to obtain quantum supremacy where they used a 53-qubit quantum computer to solve a calculation in 200 seconds, they said it would take 10,000 years for a classical supercomputer to do. This was contentious, but represented a key proof of principle in the field of quantum computing.  

At the same time, IBM released a 53-qubit quantum computer for the public through cloud services. Since then, other companies such as Rigetti and IonQ have also moved to provide early quantum computers through the cloud. While the error rates are still high, researchers and developers can begin to try using actual quantum hardware and algorithms.

While the number of qubits in current quantum computers is still modest, it is increasing constantly. IBM presented a new processor called Osprey in 2022 and it contains 433 qubits. While the milestone is more of a novelty for now, it shows the ongoing improvement in engineering and control – the two factors that will be required to make quantum computers useful for something beyond their current entertainment and novelty value.

Looking Ahead: Innovation is the progress of the quantum computing industry.

Quantum computing is yet to fully mature and this is a consensus that most analysts share today. Some near-term use cases could be expected in the next five years, for example, in the financial field, it may be used for optimizing portfolios, or in the IT field, it may help speed up machine learning. But it could take 5-10 years or even more before quantum computing starts beating classical supercomputers. 

However the pace of advancement continues to grow exponentially over the quantum computing race around the globe. Researchers in corporations such as Google, IBM, and Amazon, as well as teams in governmental and academic research facilities, continue to advance the state of the art in several domains. These are things like making better hardware, cutting down on noise and errors, creating better algorithms and applications and so on.

There is no guarantee that this will occur, but all evidence suggests that progress in the number of qubits, the ability to correct errors, and overall computational speed will only increase in the coming years. In the end of the current decade, we may have quantum computers with millions of qubits to perform useful computation that cannot be done by classical computers. Even further in the future, there is potential for quantum computers with billions of qubits, far outstripping the largest supercomputers of today.

Quantum Computing: Possibilities and Consequences

Quantum computing will be transformational for sectors such as healthcare, energy, finance, transportation, artificial intelligence, and many others. It is noteworthy that any fields that require efficient processes’ optimization, modeling of nature, or AI’s progress might be affected. Here are a few examples: Here are a few examples:

  • Healthcare: It has been claimed that quantum computing could potentially speed up the drug discovery process by predicting molecular interactions with greater precision. It could also enhance all the way from clinical trials to the flows in the hospitals.
  • Energy: Quantum algorithms could potentially lead to better solar panels by improving the modeling of the chemical processes involved. They could also improve the management of power grids. 
  • Finance: It is possible to optimize portfolios and perform risk analysis at new levels for enhancing the investments. Fraud detection may also be a beneficiary of this technology.
  • Transportation: Quantum computing could make turbulence and drag visible and assist in making better designs for aircraft and ships. It can also improve traffic patterns in smarter cities as well.
  • AI: Advanced AI and quantum machine learning algorithms can be used to develop computer vision, natural language processing, recommendation system as well as other applications.
  • Security: Decrypting current encryption methods is also feasible with the help of quantum, thus, there is a need to shift to the new quantum secure encrypting methods.

Opportunities and threats lie ahead of quantum computing, while its potential benefits seem to be vast. As presented in the preceding section, although there are seemingly positive effects in various fields as noted above, there are also negative effects such as loss of employment in sectors that such technologies negatively affect or the risk of enhanced cybercrime. The process will be to be proactive in managing these risks while trying to foster innovation.

In any case though, the advancement in quantum computing is likely to be good for the economy as well as the science and technology fields. It brings new skills that could be useful in solving the range of issues including climate change, cancer, etc. To get the optimum out of it while avoiding the risks will be one of this century’s most significant tasks.

To sum up, the transition from the research stage to physical quantum computers is progressing at a pace faster than many people anticipated. In the next decade, scale-up is expected to provide quantum computers capable of producing useful outcomes in fields beyond the reach of current supercomputers. That will create new opportunities cutting across the various industries such as health, energy, finance and many more. But there are always dangers here as well that have to be addressed. If today’s investment and research is sustained, quantum computing has the potential to fully realise its potential in the years ahead to create a better world.
