Quantum computers have the potential to speed up computation, help design new medicines, break codes, and discover exotic new materials — but that’s only when they are truly functional. One key thing that gets in the way: noise or the errors that are produced during computations on a quantum machineContinue Reading
Scientists from TU Delft (The Netherlands) have observed quantum spin currents in graphene for the first time without using magnetic fields. These currents are vital for spintronics, a faster and more energy-efficient alternative to electronics. This breakthrough, published in Nature Communications, marks an important step towards technologies like quantum computingContinue Reading
Quantum computers can solve extraordinarily complex problems, unlocking new possibilities in fields such as drug development, encryption, AI, and logistics. Now, researchers at Chalmers University of Technology in Sweden have developed a highly efficient amplifier that activates only when reading information from qubits. Thanks to its smart design, it consumesContinue Reading
Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also key in security; if a password or code is an unguessable string of numbers, it’s harder to crack. Many ofContinue Reading
For decades, quantum computers that perform calculations millions of times faster than conventional computers have remained a tantalizing yet distant goal. However, a new breakthrough in quantum physics may have just sped up the timeline. In an article published in PRX Quantum, researchers from the Graduate School of Engineering Science andContinue Reading
UBC researchers are proposing a solution to a key hurdle in quantum networking: a device that can “translate” microwave to optical signals and vice versa. The technology could serve as a universal translator for quantum computers — enabling them to talk to each other over long distances and converting upContinue Reading
Similar to humans going on journeys of self-discovery, quantum computers are also capable of deepening their understanding of their own foundations. Researchers from Tohoku University and St. Paul’s School, London, have developed a new algorithm that allows quantum computers to analyze and protect quantum entanglement — a fundamental underpinning ofContinue Reading
Scientists based at the AWS Center for Quantum Computing on Caltech’s campus have made a leap forward in figuring out how to suppress errors in quantum computers, a pesky problem that continues to be the greatest hurdle to building the machines of the future. Quantum computers, which are based onContinue Reading
Working at nanoscale dimensions, billionths of a meter in size, a team of scientists led by the Department of Energy’s Oak Ridge National Laboratory revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements, published in Nano Letters, could be used to advanceContinue Reading
Newly achieved precise control over light emitted from incredibly tiny sources, a few nanometers in size, embedded in two-dimensional (2D) materials could lead to remarkably high-resolution monitors and advances in ultra-fast quantum computing, according to an international team led by researchers at Penn State and Université Paris-Saclay. In a recentContinue Reading
