Commercially Available Silicon Quantum Computer Moves Forward With Quietest Bits On Record

KEY POINTS

  • Physicists achieve a noise level 10 times lower than the previous record
  • Demonstration proves to take a major step closer to a full-scale silicon quantum processor 
  • Next step could be a 10-qubit prototype quantum integrated processor by 2023

The lowest noise level on record for a semiconductor quantum bit has been demonstrated by a team of quantum physicists, bringing the development of a commercially available silicon quantum computer one step forward to possibility. 

In a study published in Advanced Materials, the physicists said they were able to achieve a noise level 10 times lower than previously recorded for any semiconductor qubit. Specifically, they demonstrated a low-level charge noise of  S0 = 0.0088 ± 0.0004 μeV2 Hz−1. 

As a next step, the team is now looking forward to demonstrating the capability required to produce a reliable 10-qubit prototype quantum integrated processor by 2023. 

“Our team is now working towards delivering all of these key results on a single device – fast, stable, high fidelity and with long coherence times – moving a major step closer to a full-scale quantum processor in silicon,” Michelle Simmons, director for Center for Quantum Computation and Communication Technology (CQC2T) and Scientia professor of quantum physics in the Faculty of Science at the University of New South Wales, said in a press release. 

The team explained that, for a silicon quantum computer to perform reliable and applicable solutions, it should generate quantum information close to 100% accuracy. However, achieving such accuracy was impossible due to what physicists call charge noise. 

Imperfections in the material environment that hosts qubits result in charge noise. It impedes the proper encoding of information on qubits, affecting the information accuracy altogether. By separating the qubits from the surface and interface states, the team was able to demonstrate the lowest noise

PC Sales Just Broke A 10-Year Record Thanks To The Pandemic

The global PC market grew by almost 13% in the third quarter, according to Canalys, marking the biggest surge in sales in the last decade.

According to the analyst firm’s estimates, shipments of PC and laptop devices reached 79.2 million units during the quarter, an increase of 12.7%, as sales “continued to benefit hugely from the COVID-19 crisis”.

Laptops accounted for the majority fo these sales, with 64 million units shipped during the third quarter as employees continue to work from home. Laptop and mobile workstation shipments also saw sales increased by 28.3% year over year, though desktop and desktop workstations saw a 26% decline in shipments.

“Vendors, the supply chain, and the channel have now had time to find their feet and allocate resources towards supplying notebooks, which continue to see massive demand from both businesses and consumers,” commented Canalys analyst Ishan Dutt .

Lenovo regained the top stop in the market during the third quarter, with 11.4% growth and shipments reaching more than 19 million. HP ranked second, with growth of 23.6% and shipments totalling 18.7 million, while Dell earned the number three spot despite a 0.5% drop in shipments compared to last year. 

Apple and Acer claimed the fourth and fifth spots with growth of 13.2% and 15%, respectively.

Canalys says it expects the pandemic to have “lasting effects” on the way people work and learn beyond the pandemic as companies continues to to invest in longer-term transitions to remote working, adding that IT expenditure, including investment in PCs, will likely be a core driver of economic

How to automatically record meetings on Zoom using your computer

  • You can set Zoom to automatically record all the meetings that you host.
  • When changing your Zoom settings, you can also choose whether you want the recordings to be saved to your computer or the cloud.
  • For added transparency, you can turn on the “Recording consent” feature to let others in the call know when you’re recording.

You can easily turn on the “Automatic Record” feature in your Zoom settings online, and begin recording your Zoom calls.

Like other Zoom actions, such as the ability to mute and unmute participants, automatically recording the meeting only applies if you are the host.

It’s important to note that you are also unable to make any of these changes in the Zoom app for desktop or mobile, and can only be done in the browser.

Once you start recording, you can enable the “Recording consent” function to let participants know that you are recording.

Here’s how to do it.

How to automatically record meetings on Zoom

1. Open Zoom in your browser on your Mac or PC.

2. Click on “My Account” in the top-right corner.

3. This will bring you to your profile and settings pages. Click the “Settings” tab under the “Personal” section in the left hand panel.

4. Click the “Recording” tab at the top.

5. Make sure “Local recording” is switched to on first. If this isn’t turned on, you won’t be able to save recordings at all — regardless of whether or not they are automatic.

6. Next, click the toggle next to “Automatic recording” to turn it on. If the feature is turned on, the switch will turn from gray

IT Giant TCS Surges to Record After Unveiling $2 Billion Buyback

(Bloomberg) —

Tata Consultancy Services Ltd. surged to a record high after the Indian giant announced a share buyback of as much as 160 billion rupees ($2.2 billion) and said technology spending was recovering faster than anticipated.

Asia’s largest software outsourcing provider reported a larger-than-expected 7% fall in net income to 74.7 billion rupees in the September quarter. But Chief Executive Officer Rajesh Gopinathan said IT budgets were bouncing back and growth should accelerate as clients spend on digital services such as cloud migration, security and work tools to trim costs and adjust to a post-pandemic environment.

Tata Consultancy Services CEO Rajesh Gopinathan Presents First Earnings Since Mistry Court Ruling

Like Infosys Ltd. and Wipro Ltd., TCS is struggling to serve global financial services giants and corporate clients after a nationwide lockdown forced hundreds of thousands of their employees to work from home. But spending is loosening as lockdowns ease globally and their customers build out their digital infrastructure. TCS’s shares gained as much as 5.2% Thursday, becoming the best performer on the benchmark Sensex, after brokerages including Dalal & Broacha and IDBI Capital raised their recommendations on the stock.

“The recovery is happening a quarter earlier than we expected, it is sustainable and has strong legs,” Gopinathan said during a post-earnings briefing. “But we are not fully out of the woods and need to be careful on the economic and health fronts.”

What Bloomberg Intelligence Says

Tata Consultancy Services is poised to see growth recover over the next 2-3 quarters as discretionary IT spending rebounds, especially among banking clients. A boost in spending on digital transformations and a need to save more on their total IT costs will be the main drivers. Tata’s unique culture, brand and low attrition rate is a major differentiator compared
