Scientists Succeed in Measuring Electron Spin Qubit Without Demolishing It RIKEN

March 3, 2020

Scientists at the RIKEN Center for Emergent Matter Science in Japan have successfully measured electron spin in a silicon quantum dot (QD) without altering its spin. Such measurements have been difficult, as spin typically is impacted by the process of reading out single electron spins in silicon, which is to convert the spins into charges for fast detection. The researchers used the Ising model to transfer spin data of an electron in a QD to an electron in a neighboring QD; they then were able to measure the neighbor’s spin while leaving the original electron untouched. Using this method, said RIKEN’s Seigo Tarucha, yielded a non-demolition fidelity rate of 99%, a readout accuracy of 95%, and a theoretical accuracy upgrade to 99.6%.

How the Cloud Has Opened Doors for Hackers

Corporate transfers of operations to the cloud have elevated the threat of hacking, as the cloud can be accessed remotely with ease. Manav Mital, co-founder of cloud security startup Cryal, said cloud companies manage the upkeep and security of physical servers, but client requirements for ease of access have spawned new apps and databases, and increasingly complex services that are difficult to manage and monitor. Although companies still shield private data behind firewalls and other security measures, more people and programs require access to data in the cloud, making it easier for bad actors to find potential vulnerabilities. The Ponemon Institute estimated that cloud breaches cost each individual company $3.92 million on average.

Cal Receives Largest Donation Ever—$252M—for Datacenter

The University of California, Berkeley (UC Berkeley) received an anonymous $252-million donation, which will be used to break ground on the Data Hub, a facility for students and faculty studying computing and data science. This gift is the largest donation ever given to the school, while the datacenter’s completion will require another $300 million. The Data Hub will contain the university’s Division of Computing, Data Science, and Society. UC Berkeley’s Jennifer Chayes said the facility “will be a magnet, bringing together scholars from disciplines across campus to forge new collaborations and take on some of the most critical questions facing society today, from biomedicine, to climate change and sustainability, to making data-informed public policy on issues of societal significance.”
