Developed a chip that can withstand the cold of space

22.03.2023

New York-based quantum computing startup SEEQC has announced a digital chip that can operate at temperatures below the cold of space. This will allow it to be used with quantum processors located in cryogenic chambers.

Quantum computers use the features of quantum physics to solve problems that are impossible or very difficult to solve on conventional computers. However, quantum bits or qubits, which are the main elements of quantum computers, are very sensitive to external influences and can lose their state. Therefore, they require cooling to temperatures close to absolute zero (about -273°C).

To manage and control qubits, it is necessary to have a classical computer chip that can communicate with a quantum processor. However, most existing classical chips cannot operate at such low temperatures and must be placed outside the cryogenic chamber. This interferes with signal transmission and increases power consumption and noise.

Startup SEEQC solved this problem - their new chip will allow for fast and reliable information exchange between a classical and quantum computer. In addition, the development of startup engineers is able to execute complex algorithms to control and optimize the operation of qubits without the need to send data to an external computer. The processor is also smaller and consumes less power.

And although SEEQC claims to have created the world's first chip capable of operating in the same cryogenic environment as qubits, the startup has many competitors. For example, IBM, Google, Microsoft, Intel and Amazon have their own programs and platforms for quantum computing. There are also other startups such as IonQ, Rigetti Computing and D-Wave Systems that offer quantum processors and cloud services.

However, the development of SEEQC differs from others in that it uses an approach called Digital Quantum Computing. This means that the project's engineers are integrating a classical and quantum computer into a single chip using superconducting technology. This reduces the complexity and cost of creating and operating quantum computers.

The startup SEEQC also has its own Chip Foundry & Fabrication Lab in New York, where it can test and optimize its chips for different kinds of qubits. In addition, the company's specialists collaborate with various partners around the world to develop and demonstrate programs based on their chip.

SEEQC is leading a project called QCAT (Quantum Computing for Advanced Technologies) funded by the UK government. The goal of this project is to build a full-fledged quantum computer based on the SEEQC digital chip and demonstrate its application in various fields such as machine learning, optimization, and medical research.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Artificial skin feeling pain 01.09.2020

Scientists from the Royal Melbourne University of Technology have developed an electronic artificial skin that can respond to pain like a human.

The device mimics the body's near-instantaneous feedback and can respond to pain at the same rate that nerve signals reach the human brain.

Until now, no technology has been created that could realistically reproduce the feeling of pain familiar to every person, said lead author of the study, Professor Madhu Bhaskaran. - Our invention reacts instantly when ambient pressure or temperature reaches the pain threshold

According to experts, electronic skin is able to feel the difference between the impacts and respond even to a light touch of a finger on a pin.

The new technology can be used to create bionic prostheses, intelligent robotics, and will also become necessary in the field of non-invasive skin transplantation.
