Smallest Quantum Computer Developed
A group of researchers working at various institutes in Austria, Switzerland and Germany have announced that they have produced the smallest quantum computer ever developed.
For a long time, research has been conducted on quantum computers, the principle of which is explained by quantum mechanics, which can perform certain tasks much faster than conventional computers. But quantum computers that work faster than conventional computers that can be used for practical purposes have not yet been developed.
What is quantum, how does it work?
Information is encoded in bits that can take the values “0” and “1” in classical computers, and in quantum computers in cubits (quantum bits). One of the biggest problems that needs to be overcome in order for the capacity of quantum computers to rise above that of classical computers is how a large number of cubits can be combined and operated harmoniously decisively. It is estimated that a quantum computer must have at least millions of cubits to be able to perform a given task faster than conventional computers. The number of cubits owned by today’s most advanced quantum computers is expressed by them.
In quantum computers developed to date, huge systems the size of rooms were used to isolate cubits from the environment, where information was encoded and calculations were made. Dr. Ivan Pogorelov and his colleagues recently managed to develop a standard-sized quantum computer that could fit inside two shelves.
In the newly developed computer, 50 calcium ions, which act as cubits, are trapped in a volume with the help of electric fields. Coding information to cubits and reading results from cubits is done with lasers. All the necessary equipment for the operation and remote control of the computer is located in the modules inside the aluminum boxes.
The article, published in Physical Review X, states that the quantum computer is tested with a calculation that uses 24 cubits simultaneously, and its performance is much larger than it is, similar to the most advanced quantum computers.
The developed computer is said to be durable, consists of parts that can be easily replaced and requires little maintenance. It also states that the computer can be used by people all over the world through cloud-based systems.

Rate of Carbon dioxide in the Atmosphere: An Intensifying Threat
The percentage of carbon dioxide in the atmosphere has increased 43% in 141 years, rising up to the highest level ever recorded up until the present day. In 1880, the amount of carbon dioxide was approximately 291 ppm, whereas in July 2021, it was announced that the amount rose up to 417 ppm.
The extensive usage of fossil fuels, misuse of natural resources, deforestation, uncontrolled production and consumption and various human activities play a huge role in the augmentation of the amount of greenhouse gases in the atmosphere. Carbon dioxide is among the greenhouse gases, which cause the greenhouse effect and global warming.
During the pandemic, especially during the times when quarantine measures were implemented, human activity was diminished. Consequently, the rate of increase in the amount of carbon dioxide decelerated and the carbon dioxide emissions declined to some extent. However, the COVID outbreak couldn’t prevent the increase in the rate of carbon dioxide.
This rapid increase in the carbon dioxide amount constitutes a catastrophe for the Earth, humanity and other species. Augmentation in the carbon dioxide amount causes the atmosphere to vastly absorb sun rays and the heating of the planet. The intensifying temperature rates observed in recent times and melting of the ice in the poles result in alarming changes in the ecosystem. The Earth is faced with an immense threat.
