Familiarity with quantum computing, cloud computing and their differences

In the evolution of the world of technology with two concepts cloud computing (Cloud Computing) And Quantum computing (Quantum Computing) we are faced. Cloud computing It is a type of distributed computing in the cloud space that uses remote servers to perform operations; Servers that are connected to each other through the Internet. in return Quantum computing It is based on the manipulation of particles at the subatomic level. Different people and businesses should have a clear understanding of how it works before choosing each one The difference between quantum computing and cloud computing Have. For this reason, in this article, we have addressed this issue and tried to compare these two concepts from the point of view of comparison.

What is quantum computing?

Quantum computing or scientific quantum computing is based on the branch of quantum mechanics. Quantum mechanics is a part of physics that examines the characteristics and behavior of natural phenomena at the atomic and subatomic level, such as electrons and photons.

In quantum computing, computers are transformed into powerful machines by using subatomic particles to compute and process data at incredible speeds. These computers can achieve such high speed thanks to qubits (quantum bits) and the ability to zero and one or a combination of both. In contrast, the binary systems of conventional computers operate only in the zero (off or false) and one (on or true) states. In other words, qubits allow these particles to exist simultaneously in multiple states. This feature allows quantum computers to process large amounts of data simultaneously. Binary computer systems can only process one piece of information at a time.

The emergence of quantum computing dates back to the 1980s. Two physicists named Richard Feynman And Yuri Manin They realized that by using quantum theory and algorithms in calculations, better results can be obtained than classical methods.

Although applied quantum computing is still in its infancy, it has overshadowed many industries. For example, this technology helps large organizations to process huge amounts of data faster and more efficiently.

Quantum computers can decipher encrypted protocols due to their ability to solve complex problems and capabilities such as extremely fast processing of huge amounts of data or providing better predictive models on various topics. This means that quantum computers are a threat to blockchain technology and digital currencies.

What is cloud computing?

Cloud computing is an application-based software that distributes computing services across the Internet. This software takes help of third party services such as server, storage, database, networking, software and their analytics to store and receive data.

Before the advent of cloud computing, businesses had to buy servers with enough space and manage their traffic volume to avoid problems caused by hardware failures or power outages. However, most of the time, a lot of server space is left unused and a lot of money and resources are wasted. Now, cloud computing ecosystems provide an opportunity for organizations to get more efficient and cost-effective solutions without the need for expensive hardware, private data centers or software installations, focusing only on innovation, dynamic resources and economies of scale. Benefit.

The history of the invention of cloud computing goes back to the 1960s (1338); But its widespread use became common in the 2020s (1398) and during the period of the Covid-19 pandemic. In fact, in this period, we needed a more efficient computing system to manage the remote work challenges of organizations.

Thanks to cloud computing, many businesses can share their services instantly, anytime and remotely, in addition to managing, accessing, storing data and applications. By using the cloud space, these businesses can store files, applications and various types of information in a scalable way, which means saving time and money.

How does quantum computing work?

A classical processor uses bits to process operations and run various programs. In contrast, a quantum computer runs multidimensional quantum algorithms using qubits.

The execution of operations in quantum computers is done through qubits, which can simultaneously represent 0 and 1. Also, these computers use a variety of multidimensional algorithms to evaluate and implement observations. The processing power of these multidimensional spaces increases exponentially in proportion to the number of qubits that are added.

Quantum computers are smaller and require less energy than supercomputers. Of course, supercomputers are also more efficient than normal computers. A quantum processor is about the size of a laptop processor. The components of a quantum hardware system also mostly include cooling systems.

Quantum computers are sensitive tools with a high error rate; For this reason, the hardware device of these computers must be kept at a very cold temperature close to absolute zero. These cooling systems, called superfluid or superfluid, must be able to reduce the temperature of the processors extremely low to create a superconducting state. In such conditions, electrons move without resistance, quantum information is generated faster and more efficiently, and complex multidimensional spaces are created in proportion to the number of added qubits.

Advantages and disadvantages of quantum computing

A better understanding of the mechanism of quantum computing will be possible by examining its advantages and disadvantages, some of which are mentioned below.

Advantages:

• Creating an opportunity for various industries to develop and design advanced computer programs based on highly accurate, safe and efficient data.
• Access to advanced data encryption methods to better detect fraud and ensure public security of sensitive data
• Extreme data processing speed to handle large amounts of data at once (note that it is impossible to achieve such speed on ordinary computers.)
• A revolution in the creation of new materials, drugs and chemicals thanks to the simulation of molecular structure by quantum computing

Disadvantages:

• Due to the fact that quantum calculations are sensitive to the intervention of external factors such as temperature and electromagnetic radiation, the accuracy of calculations is also affected.
• Quantum computers are not widely available; Therefore, developers cannot properly evaluate their features and reliability.
• Quantum computers require a large amount of data to function properly; As a result, businesses have to invest in massive data storage systems to use these computers.

How does cloud computing work?

Cloud computing systems are maintained and implemented by specialized companies. These companies have large data centers and can provide the security, storage capacity, and computing power necessary to support online infrastructure.

Cloud services are accessible through an Internet connection and computing devices such as smartphones, laptops, and computers. Users can easily choose a cloud computing company and use their services by paying a fee. These services include the necessary infrastructure to facilitate communication between devices and programs. For example, the user can save a file on his laptop and the same moment the file is synchronized on his iPhone device.

Cloud computing architecture is divided into front-end and back-end. The front-end section includes all the client’s access tools to the cloud computing system. For example, users can access their saved data with a web browser. Back-end also refers to servers, computers, databases and central servers. Central servers use special protocol rules to facilitate the implementation of operations and ensure smooth and trouble-free communication between devices connected to the cloud.

Some cloud service providers are technology pioneers. These companies include Amazon Web Services, Microsoft Azure, Apple iCloud, and Google Drive.

Advantages and disadvantages of cloud computing

For a better comparison between the two concepts that we intend to examine in this article, it is better to examine the advantages and disadvantages of cloud computing.
