U.S. chip goliath Qualcomm has said it is open to the idea of investing in U.K. chip designer Arm if the company’s $40 billion sale to Nvidia is blocked by regulators, according to The Telegraph newspaper.

Qualcomm’s incoming CEO, Cristiano Amon, said Qualcomm would be willing to buy a stake in Arm alongside other industry investors if SoftBank, Arm’s current owner, listed the company on the stock market instead of selling it to Nvidia, the newspaper reported Sunday.

“If Arm has an independent future, I think you will find there is a lot of interest from a lot of the companies within the ecosystem, including Qualcomm, to invest in Arm,” Amon said. “If it moves out of SoftBank and it goes into a process of becoming a publicly-traded company, [with] a consortium of companies that invest, including many of its customers, I think those are great possibilities.”

German nanotechnology specialist attocube says its attoDRY800 cryostat enables quantum scientists to “reclaim the optical table” and focus on their research not the experimental set-up.

Twin-track innovations in cryogenic cooling and optical table design are “creating the space” for fundamental scientific breakthroughs in quantum communications, allowing researchers to optimize the performance of secure, long-distance quantum key distribution (QKD) using engineered single-photon-emitting light sources.

In a proof-of-concept study last year, Tobias Heindel and colleagues in the Institute of Solid State Physics at the Technische Universität (TU) Berlin, Germany, implemented a basic QKD testbed in their laboratory. The experimental set-up uses a semiconductor quantum-dot emitter to send single-photon pulses along an optical fibre to a four-port receiver that analyses the polarization state of the transmitted qubits.

LYNCHBURG, Va (WSET) — Strangers may soon be able to use your Wi-Fi — It’s all through Amazon Sidewalk.

It’s an internet-sharing network for Amazon Echo, Ring and Tile devices. Officials say it’s a way to use WiFi from neighboring homes that also have Amazon products.

Randy Marchany a cybersecurity expert with Virginia Tech feels this is another way to collect information. He says it’s specifically picking up on user habits and whereabouts.
