New Quantum Computing Architecture Could Be Used To Connect Large-Scale Devices

Quantum computers hold the promise of performing certain tasks that are intractable even on the world’s most powerful supercomputers. In the future, scientists anticipate using quantum computing to emulate materials systems, simulate quantum chemistry, and optimize hard tasks, with impacts potentially spanning finance to pharmaceuticals. However, realizing this promise requires resilient and extensible hardware. One challenge in building a large-scale quantum computer is that researchers must find an effective way to interconnect quantum information nodes — smaller-scale processing nodes separated across a computer chip. Because quantum computers are fundamentally different from classical computers, conventional techniques used to communicate electronic information do…

MIT Researchers Use Quantum Computing To Observe Entanglement

For the first time, researchers at MIT, Caltech, Harvard University, and elsewhere sent quantum information across a quantum system in what could be understood as traversing a wormhole. Though this experiment didn’t create a disruption of physical space and time in the way we might understand the term “wormhole” from science fiction, calculations from the experiment showed that qubits traveled from one system of entangled particles to another in a model of gravity. This experiment performed on the Sycamore quantum processor device at Google opens the doors to future experiments with quantum computers to probe ideas from string theory and…

Quantum Sensor Can Detect Electromagnetic Signals Of Any Frequency

Quantum sensors, which detect the most minute variations in magnetic or electrical fields, have enabled precision measurements in materials science and fundamental physics. But these sensors have only been capable of detecting a few specific frequencies of these fields, limiting their usefulness. Now, researchers at MIT have developed a method to enable such sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. The new method, for which the team has already applied for patent protection, is described in the journal Physical Review X, in a paper by graduate student Guoqing Wang, professor of nuclear science and…

Better AI, Unhackable Communication, Spotting Submarines: The Quantum Tech Arms Race Is Heating Up

Quantum technology, which makes use of the surprising and often counterintuitive properties of the subatomic universe, is revolutionising the way information is gathered, stored, shared and analysed. The commercial and scientific potential of the quantum revolution is vast, but it is in national security that quantum technology is making the biggest waves. National governments are by far the heaviest investors in quantum research and development. Quantum technology promises breakthroughs in weapons, communications, sensing and computing technology that could change the world’s balance of military power. The potential for strategic advantage has spurred a major increase in funding and research and…

Making Quantum Circuits More Robust

Quantum computing continues to advance at a rapid pace, but one challenge that holds the field back is mitigating the noise that plagues quantum machines. This leads to much higher error rates compared to classical computers. This noise is often caused by imperfect control signals, interference from the environment, and unwanted interactions between qubits, which are the building blocks of a quantum computer. Performing computations on a quantum computer involves a “quantum circuit,” which is a series of operations called quantum gates. These quantum gates, which are mapped to the individual qubits, change the quantum states of certain qubits, which…

How IBM Quantum Is Advancing Physics With World-Leading Theory Research

IBM Quantum isn’t just building quantum computers — we’re developing an ecosystem around a technology which pushes the limit of human knowledge. In order to navigate forward in this field, we must rely on theoretical physicists to chart the course. You can think of IBM Quantum’s theorists as writing quantum computing’s rulebook. Theorists research the ability of classical and quantum computing at the most basic level in order to determine what kinds of advantages quantum might offer. They help create strategies to mitigate errors and improve our device performance in the short term, while figuring out how to correct errors…

Tiny Materials Lead To A Big Advance In Quantum Computing

Like the transistors in a classical computer, superconducting qubits are the building blocks of a quantum computer. While engineers have been able to shrink transistors to nanometer scales, however, superconducting qubits are still measured in millimeters. This is one reason a practical quantum computing device couldn’t be miniaturized to the size of a smartphone, for instance. MIT researchers have now used ultrathin materials to build superconducting qubits that are at least one-hundredth the size of conventional designs and suffer from less interference between neighboring qubits. This advance could improve the performance of quantum computers and enable the development of smaller…

New Qubits Could Make Quantum Computers More Compact

Villigen – Researchers from the Paul Scherrer Institute based in Villigen in the canton of Aargau are focused on the creation of topological quantum bits. These quantum bits, or qubits for short, form the basis of future quantum computers. More stable and therefore superior topological qubits would make quantum computers particularly efficient and compact.
