There's a good old fashioned nerd fight brewing between the eggheads at IBM and Google. Don't worry, it's not physical—it's a war of words and theoretical concepts. What sparked the debate is Google's claim of achieving "quantum supremacy" with Sycamore, a system outfitted with a 53-qubit processor and how it performs compared to a classical supercomputer in a specific task. Google conceived an experiment to demonstrate just how capable Sycamore is, noting it can complete a certain benchmark test in 200 seconds, whereas "a state-of-the-art supercomputer would require approximately 10,000 years to perform the equivalent task." The spunky Mountain View firm details the experiment in a blog... Read more...
We are a little bit closer to making quantum computing an everyday reality. Google researchers reportedly created a quantum computer that has achieved “quantum supremacy”. The quantum computer was able to solve equations that would be nearly impossible for a supercomputer. Google researchers recently developed “Sycamore”, a 53-qubit quantum computer. The computer was able to solve a mathematical equation that would have taken a supercomputer 10,000 years to solve, in a mere 200 seconds. They have also claimed that Sycamore performed another equation in 30 seconds that would have taken the Google Cloud server 50 trillion years to process. A researcher remarked, “This... Read more...
Beam me up, Scotty. Scientists have recently announced that they have achieved complex quantum teleportation. Multidimensional teleportation could have a strong impact on quantum computing and communication. Researchers from the Austrian Academy of Sciences, University of Vienna, and University of Science and Technology of China successfully teleported a three-dimensional quantum state. They were able to teleport the quantum state of a photon or light particle to another. Scientists have theorized that this kind of transportation is possible since the 1990s, but have not been able to prove it. Teleportation does not transport matter, but instead moves quantum information. The scientists were... Read more...
Researchers from Oregon State University (OSU) have announced that they have created a new material that is a key step in creating the next generation of supercomputers. These next-generation quantum computers will be far faster than current supercomputers while consuming much less energy. The scientists on the project work in the OSU College of Science and the compound they have developed is an inorganic material that adopts a crystal structure. The material is capable of sustaining a new state of matter that is known as quantum spin liquid. That new compound is lithium osmium oxide and it has osmium atoms that form a honeycomb-like lattice, and can enforce a phenomenon called "magnetic... Read more...
Google has developed a new quantum processor called Bristlecone that it hopes will be instrumental in building a quantum computer capable of solving real-world problems. At the American Physical Society meeting in Los Angeles where the chip was unveiled, Google said the purpose of its gate-based superconducting system is to provide a testbed for research into system error rates and scalability of its qubit technology, along with applications in quantum simulation, optimization, and machine learning. "In order for a quantum processor to be able to run algorithms beyond the scope of classical simulations, it requires not only a large number of qubits. Crucially, the processor must also have low...

Coffee Lake is not the only thing Intel has been brewing up. The world's largest semiconductor company announced the delivery of a 17-qubit superconducting test processor for quantum computing to QuTech, its quantum research partner based in the Netherlands. Intel fabricated the chip with a unique design to improve yield and performance, the Santa Clara chip maker said. By no means is the world of quantum computing new terrain for Intel, which has been working with QuTech for the past couple of years on research and development aimed at producing a working quantum computing system. Such a thing would be a major leap in parallel computing, as it would enable scientists and researchers to tackle... Read more...
IBM Research is giving back to the world today with the announcement that its quantum processor is now accessible by the public. The project is called the IBM Quantum Experience and allows regular Joes (and Janes) to manipulate individual quantum bits (or qubits) so that they can test algorithms or run experiments. Making its superconducting 5-qubit processor publicly-accessible should go a long way towards validating the immense work that is being performed behind the scenes to usher in a new era of computing. “This moment represents the birth of quantum cloud computing. By giving hands-on access to IBM’s experimental quantum systems, the IBM Quantum Experience will make it easier for researchers... Read more...
Intel is investing $50 million and "significant engineering resources" into quantum computing. It's part of a decade-long collaborative effort with QuTech, a quantum research institute belonging to Delft University of Technology (TU Delft) in the Netherlands and the Dutch Organization for Applied Research. Quantum computing has long been considered the Holy Grail of processing. It's completely different from today's transistor-based computing models and is capable of solving much more complex problems, including intricate simulations like large-scale financial analysis and drug development. Intel's investment and long-term commitment in the field is a big deal, though even with the weight of... Read more...
If you're reading this site, chances are you have heard of Moore's Law. You may have even heard of the law of diminishing returns. Or perhaps you've heard that fast is never fast enough, and big is never big enough. But have you heard of quantum computing? Most people hear that phrase and simply think of some science fiction movie that they have seen in the past. But outside of Hollywood fantasies, it rarely has any real meaning for the average consumer. That's mostly because quantum computing is still a pipe dream in real life, and even after decades of using silicon microchips to power our computers, we're still largely using the same process as we started with. 16-qubit processor in holder...
