Quantum Circuit Generator Accelerates Quantum Computing

Image
An international group of researchers from Fujitsu Limited and the Center for Quantum Information and Quantum Biology at Osaka University has announced the development of two new technologies for a space-time efficient analog rotation quantum computing architecture. These innovations are expected to significantly advance the realization of practical quantum computing. The first technology improves the accuracy of phase angle adjustments during phase rotations, while the second automatically generates effective qubit operation procedures. With these advancements, Fujitsu and QIQB have demonstrated that a quantum computer could theoretically perform a calculation in 10 hours that would take a classical computer five years to complete. The specific computation, which involved estimating material energy, was shown to be achievable with only 60,000 qubits—a much smaller number than typically considered necessary for fault-tolerant quantum computation (FTQC) to surpass classical computing sp

Scientists show the sun's magnetic activity influences the determination of its seismic age

  An international team of astronomers, led by a researcher from the University of Geneva (UNIGE), has shown that the sun's magnetic activity has a significant influence on its seismic characterization, contrary to predictions in previous studies. Important data such as its size, age and chemical composition depend on it. These results pave the way for in-depth research to better understand the nature of the magnetic activity and its impact on stellar oscillations. The study is published in the journal Astronomy & Astrophysics. Asteroseismology, or helioseismology in the case of the sun, is a fascinating branch of astronomy that studies the oscillations of stars. "To understand it, you must imagine a star as a big ball of gas in constant motion. Inside this star, there are waves or pulsations that make it vibrate, rather like the sound that resonates in a musical instrument," explains Jérôme Bétrisey, a postdoctoral researcher in the Astronomy Department of the Facult
