The quantum computing research is currently experiencing a significant breakthrough. A new technology has been developed that enhances the efficiency of quantum computers. This advancement builds on an old technology that first used light for communication. This could be an important step in quantum computing.
What is it about? On the page Nature Physics, researchers from the Institute of Science and Technology Austria (ISTA) report on their new technology. This allows quantum computers to generate less heat and thus work more efficiently. Quantum computing not only offers immense performance but also demands high investments in specialized technologies and extreme operating conditions.
These are quantum computers: They were born in 1981 and have established themselves as a promising alternative to conventional PCs. Quantum computers use qubits. Quantum computers utilize qubits, which, unlike classical bits, can take on multiple states simultaneously instead of just two.
Currently, they are used in research institutions and laboratories. Furthermore, they are applied in data centers to improve computing processes.
An old invention is supposed to help the quantum computer
This development is about: BBC reports that Claude Chappe developed the optical telegraph in 1792, which utilized light signals for message transmission. A technology that forms the basis of modern fiber optic technology and plays an important role today.
What problems needed to be solved? The research team identified two main problems: Firstly, the required cooling power needed to be reduced by replacing electrical cables with fiber optics. These fibers transmit light through total reflection instead of electricity and do not generate heat.
Secondly, the challenge arose that qubits cannot process optical signals directly and are also sensitive to external disturbances. To solve this problem, the researchers developed an electro-optical converter that transforms light signals into microwaves that can be processed by the qubits. This enhances both efficiency and resilience to disturbances.
The impact of quantum computers on our future
The entire development is still a prototype with much room for improvement. However, it represents a crucial first step towards quantum systems.
What impact does this have for us? According to researchers, due to advancements, multiple quantum computers could be connected via fiber optics in the near future, even at room temperature. Furthermore, according to BMBF, these advancements could influence our data traffic and its security. Since quantum computers could develop faster algorithms for data transmission and encryption. Speed could be improved, and latency times in networks could be reduced.
Last but not least, the development of quantum computers could also advance Artificial Intelligence (AI). Quantum computers would be able to analyze and process large amounts of data much faster, enhancing the capabilities of AI systems.
The future and development in the field of quantum computers promise enormous progress that could fundamentally change our lives. However, despite their impressive performance, quantum computers still cannot do everything. Because on the most powerful quantum computer for 90 million euros, you can’t even play Doom.
