In the early 1980s, renowned physicist Richard Feynman considered the potential of running a physics simulation on a computer. Despite the obstacles, Feynman and other scientists eventually made significant progress in creating revolutionary computers. These advancements have since enabled a multitude of applications, such as quantum physics research, data analysis, and addressing complex problems.
Quantum physics is a legitimate scientific field with a range of practical applications in the modern world. The laser, transistor and most modern electronics are based on quantum theory. Similarly, quantum computers use the idea that particles (or pieces of data) can exist in multiple states simultaneously.
At Works, we are always interested in the latest technologies and so we believe it would be beneficial to further our understanding of quantum computers, exploring how they work, their applications, and when we can anticipate seeing them become more commonplace.
How Does Quantum Computing Work?
Quantum computing is based on principles of quantum mechanics, which investigate the behaviour of subatomic particles. These principles make quantum computers capable of performing tasks that cannot be achieved by classical binary computers. Unlike traditional computers, which are limited to executing one task at a time, quantum computing devices are capable of carrying out multiple tasks simultaneously.
Quantum computers utilise the qubit as their primary data unit, in comparison to the bit used in traditional computers. While a bit can only take a value of either one or zero, due to its binary nature, qubits can assume both states of one and zero simultaneously. This phenomenon, known as superposition, enables quantum computers to process billions of operations per second, significantly faster than classical computers.
The dimensions of the video are 560 x 315 pixels, with a frameborder of 0 and the ability to allow accelerometer, autoplay, clipboard-write, encrypted-media, gyroscope and picture-in-picture functions with the use of fullscreen.
Quantum computers are not compatible with languages such as Java due to the need for the implementation of specialised algorithms. Furthermore, they lack the memory and processing power of a standard computer, relying solely on quantum bits. As a result, these devices are not suitable for home use due to their complexity, and are instead designed for use in academia, healthcare, technical and business environments.
Possible Applications of Quantum Computing
Quantum computers possess remarkable computational power, being able to store data in the form of quantum particles which emerge and dissipate. This could be the foundation for a quantum internet in the future.
Quantum computers have the potential to revolutionise multiple disciplines through their increased capacity for data processing and machine learning.
- Commercial – for use in resolving intricate optimization problems and doing speedy data searches
- In healthcare, specifically in the area of drug discovery
- Optimization of financial investments and enhanced fraud detection
- Improved data encryption for cyber security
- To better organize traffic and provide more fuel-efficient automobiles, transportation must undergo significant change.
Quantum computers hold the potential to revolutionise the way we tackle global scientific issues such as climate change. Current computers are already being utilised in this area, however quantum computers can provide a much faster and more accurate form of processing data.
ZDNet suggests that quantum computing networks could have far reaching implications, such as providing more accurate hurricane models that take into account every water molecule, global warming models that predict forest fires for the coming year, and pandemic models that can pinpoint which species of bat, when consumed under certain conditions, could result in future coronaviruses.
The Impact of Quantum Computing on the Future
It is unlikely that quantum computers will completely replace classical computers due to their distinct methods of operation. When using a classical computer to solve a problem, a binary response is expected; however, when using a quantum computer, one should anticipate receiving a probability as a result.
Quantum computers have the potential to revolutionise the way we solve complex problems, greatly reducing the time it takes to arrive at an answer. Additionally, they could offer new techniques for conventional computers and potentially other aspects of modern life.
- Although quantum computers may be able to break current encryption methods, they will also be able to develop far more secure alternatives.
- Quantum computers will excel at optimizing activities like the intricate logistics of delivering products or booking flights.
- In contrast to popular belief, quantum computers will actually use less power than their classical counterparts.
Quantum Computing: Some Difficulties
Due to their highly sensitive nature, quantum computers require precise environmental controls, including specific pressure and temperature levels. They must be completely sealed off from dust and other contaminants and operated by regular computers to avoid any malfunctions. Furthermore, these systems have a restricted operational window. Researchers are currently exploring ways to utilize this technology in more practical settings without a significant rise in the error rate.
Connecting quantum processors in a similar way to how computer chips are currently networked via intranets is another challenge that needs to be overcome before quantum computers can be adopted on a wider scale. This requires a complex data transmission method which has yet to be perfected.
An article in Scientific American has suggested that further research is necessary in order to progress towards the development of advanced quantum technologies and the ultimate goal of quantum information science – constructing a quantum computer that is able to perform accurate computations without errors.
How Long Before Quantum Computing Is Commonplace?
Quantum computers are unlikely to become mainstream in the near future, with widespread use not yet being achievable. Despite this, progress is being made in the field, with significant investments being made by IT giants such as IBM, Google, Microsoft and Amazon to develop quantum computing infrastructure and software.
The U.S. Department of Energy (DoE) recently announced the establishment of five new National Quantum Information Science Research centers, with the funding allocated as part of the National Quantum Initiative Act of 2023 amounting to $625 million over a five-year period.
When Will We See the Next Steps in Quantum Computing?
It is impossible to predict the advancements that quantum computing may bring, just as it was not possible to envision the numerous applications for traditional computers and the internet. We can anticipate to hear more about this innovative technology in the upcoming years, as researchers, government representatives, corporate leaders, and others are investigating its many possible applications.
