It’s not often that 5-year-olds can grasp questions at the frontiers of computer science, but it can happen. Suppose, for instance, that a kindergartner named Alice has two apples, but she prefers oranges. Fortunately, her […]
An international research team led by quantum physicist Markus Arndt (University of Vienna) has achieved a breakthrough in the detection of protein ions: Due to their high energy sensitivity, superconducting nanowire detectors achieve almost 100% […]
A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein’s classical concept of spacetime has been announced in two papers published simultaneously by UCL (University College London) physicists. Click to rate this […]
The field of attosecond physics was established with the mission of exploring light–matter interactions at unprecedented time resolutions. Recent advancements in this field have allowed physicists to shed new light on the quantum dynamics of […]
Quantum 7, 1195 (2023). https://doi.org/10.22331/q-2023-12-04-1195 The recovery of fragile quantum states from decoherence is the basis of building a quantum memory, with applications ranging from quantum communications to quantum computing. Many recovery techniques, such as […]
Quantum 7, 1194 (2023). https://doi.org/10.22331/q-2023-12-04-1194 A standard approach to quantifying resources is to determine which operations on the resources are freely available, and to deduce the partial order over resources that is induced by the […]
Quantum 7, 1193 (2023). https://doi.org/10.22331/q-2023-12-04-1193 The quasicharge superconducting qubit realizes the dual of the transmon and shows strong robustness to flux and charge fluctuations thanks to a very large inductance closed on a Josephson junction. […]
Insider Brief String theory and loop quantum gravity are the current leading candidates for a quantum theory of gravity. New theory suggests that that spacetime may be classical and not governed by quantum theory at […]
Insider Brief Meta’s leadership doesn’t believe quantum computing will be relevant to their business. The team also sees artificial general intelligence — AGI — as a distant threat/opportunity. Chief scientist Yann LeCun discussed his opinion […]
Insider Brief Algorithmiq reports it successfully ran a large-scale error mitigation experiments to date on IBM’s hardware. Algorithmiq’s proprietary error mitigation algorithms were run on the IBM Nazca, the 127 qubit Eagle processor. The team […]
