Researchers at Swansea University have discovered a way to use mirrors to dramatically reduce the quantum noise that disturbs tiny particles — a breakthrough that might seem magical but is rooted in quantum physics. When scientists measure extremely small objects, such as nanoparticles, they face a difficult challenge: simply observingContinue Reading
In the future, quantum computers could rapidly simulate new materials or help scientists develop faster machine-learning models, opening the door to many new possibilities. But these applications will only be possible if quantum computers can perform operations extremely quickly, so scientists can make measurements and perform corrections before compounding errorContinue Reading
A research team at Tohoku University’s Advanced Institute for Materials Research (WPI-AIMR) has developed a new technique to rapidly and accurately determine the charge state of electrons confined in semiconductor quantum dots — fundamental components of quantum computing systems. The method is based on Bayesian inference, a statistical framework thatContinue Reading
Researchers have developed a new protocol for benchmarking quantum gates, a critical step toward realizing the full potential of quantum computing and potentially accelerating progress toward fault-tolerant quantum computers. The new protocol, called deterministic benchmarking (DB), provides a more detailed and efficient method for identifying specific types of quantum noiseContinue Reading
Researchers at the University of Rochester and Rochester Institute of Technology recently connected their campuses with an experimental quantum communications network using two optical fibers. In a new paper published in Optica Quantum, scientists describe the Rochester Quantum Network (RoQNET), which uses single photons to transmit information about 11 milesContinue Reading
A team of researchers has developed a technique that makes high-dimensional quantum information encoded in light more practical and reliable. This advancement, published in Physical Review Letters, could pave the way for more secure data transmission and next-generation quantum technologies. Quantum information can be stored in the precise timing ofContinue Reading
Quantum physics keeps challenging our intuition. Researchers at the University of Geneva (UNIGE) have shown that joint measurements can be carried out on distant particles, without the need to bring them together. This breakthrough relies on quantum entanglement — the phenomenon that links particles across distance as if connected byContinue Reading
The connection between a crumpled sheet of paper and quantum technology: A research team at the EPFL in Lausanne (Switzerland) and the University of Konstanz (Germany) uses topology in microwave photonics to make improved systems of coupled cavity arrays. Smaller, more versatile, and more powerful: a team of physicists fromContinue Reading
Whether bismuth is part of a class of materials highly suitable for quantum computing and spintronics was a long-standing issue. Kobe University research has now revealed that the true nature of bismuth was masked by its surface, and in doing so uncovered a new phenomenon relevant to all such materials.Continue Reading
Konstantin Vodopyanov, a professor at the College of Sciences and CREOL, the College of Optics and Photonics, recently co-authored a study published in the journal Optica. This research examines electro-optic sampling (EOS), a technique that advances fields such as quantum physics, molecular spectroscopy and biomedical sensing. As a professor atContinue Reading
