On the afternoon of September 30, 1906, a crowd of 200,000 Parisians congregated near the city’s center to watch the premiere of what would become the world’s most prestigious gas balloon race. Sixteen of the […]
Two-dimensional (2D) materials have proved to be a promising platform for studying exotic quasiparticles, such as excitons. Excitons are bound states that emerge when an electron in a material absorbs energy and rises to a […]
The Netherlands’ HQ/2 initiative, involving QuTech, TNO, and four startups—QuantWare, Qblox, Orange Quantum Systems, and Delft Circuits—has released Tuna-5, a superconducting quantum system built using an open-architecture model. Hosted at the DiCarlo Lab and available […]
A new study explores how EOS transmits ultrashort laser pulses through crystals that change in response to an applied electric field. This technique allows researchers to accurately capture the shape and timing of electric fields […]
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 […]
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 […]
A new study published in Physical Review D titled, “Extending the Bridge Connecting Chiral Lagrangians and QCD Gaussian Sum-Rules for Low-Energy Hadronic Physics,” offers significant advancements in the understanding of the strong nuclear force. This […]
By extending a key law in quantum information to systems with long-range interactions, RIKEN physicists have enhanced its usefulness. This advance could help to design better quantum computers. Click to rate this post! [Total: 0 […]
Quantum 9, 1747 (2025). https://doi.org/10.22331/q-2025-05-15-1747 Block Encoding (BE) is a crucial subroutine in many modern quantum algorithms, including those with near-optimal scaling for simulating quantum many-body systems, which often rely on Quantum Signal Processing (QSP). […]
