IBM Launches $100 Million Partnership with Global Universities to Develop Novel Technologies Towards a 100,000-Qubit Quantum-Centric Supercomputer

Over the next decade, IBM plans to work with university partners and its worldwide quantum ecosystem to evolve how its quantum processors can be connected via quantum interconnects. This work will aim to enable high-efficiency, high-fidelity inter-processor quantum operations and a reliable, flexible, and affordable system component infrastructure to allow scaling to 100,000 qubits.

IBM‘s collaboration with the University of Chicago will build upon the Chicago area‘s strengths in quantum research. The University of Chicago seeded the region‘s quantum ecosystem more than a decade ago with the decision to make quantum technology a focus of what is now the Pritzker School of Molecular Engineering.

Solar differential rotation reproduced with high-resolution simulation

(Published: 13 September 2021)

Here, we show that a high-resolution calculation succeeds in reproducing the solar-like differential rotation. Our calculations indicate that the strong magnetic field generated by a small-scale dynamo has a significant impact on thermal convection. The successful reproduction of the differential rotation, convection and magnetic field achieved in our calculation is an essential step to understanding the cause of the most basic nature of solar activity, specifically, the 11 yr cycle of sunspot activity.

Accurate Simulation of Sun’s Rotation Might Illuminate Solar Cycle

(08.11.2021)

Japanese scientists said they have created the first accurate computer simulation of how the Sun rotates, reproducing a phenomenon in which its equatorial area spins faster than its polar regions. The insight could help explain the whys and hows of the solar cycle, one of the biggest mysteries of our star.

In a NASA simulation of an asteroid impact, scientists concluded they couldn‘t stop a space rock from decimating Europe

(01.05.2021)

The experts fell short. The group determined that none of Earth‘s existing technologies could stop the asteroid from striking given the six-month time frame of the simulation. In this alternate reality, the asteroid crashed into eastern Europe.

DEADLY DATA: Plan to lift lockdown by Easter ‘was canned after Sage scientists warned it would cause 91,000 more deaths

Models predicted it would lead to nearly 60,000 Covid patients in hospital by June, compared to last month‘s high of 39,000.

Chief Scientific Adviser Sir Patrick Vallance spoke of his support for the gradual approach taken by PM Boris Johnson, saying: „The sooner you open up everything, the higher the risk of a bigger resurgence.

„The slower you do it, the better.“

Large scale structure formation in the Universe simulated

Apr 2, 2009

This is a simulation of structure formation in the Universe using the adhesion approximation. The algorithm is described by Weinberg and Gunn in MNRAS in 1990

The Cosmic Web, or: What does the universe look like at a VERY large scale?

Nov 6, 2010

The Millennium Simulation featured in this clip was run in 2005 by the Virgo Consortium, an international group of astrophysicists from Germany, the United Kingdom, Canada, Japan and the United States.
