Old computer technology points the way to future of quantum computing

Published

 on

VANCOUVER — Researchers have made a breakthrough in quantum technology development that has the potential to leave today’s supercomputers in the dust, opening the door to advances in fields including medicine, chemistry, cybersecurity and others that have been out of reach.

In a study published in the journal Nature on Wednesday, researchers from Simon Fraser University in British Columbia said they found a way to create quantum computing processors in silicon chips.

Principal investigator Stephanie Simmons said they illuminated tiny imperfections on the silicon chips with intense beams of light. The defects in the silicon chips act as a carrier of information, she said. While the rest of the chip transmits the light, the tiny defect reflects it back and turns into a messenger, she said.

There are many naturally occurring imperfections in silicon. Some of these imperfections can act as quantum bits, or qubits. Scientists call those kinds of imperfections spin qubits. Past research has shown that silicon can produce some of the most stable and long-lived qubits in the industry.

“These results unlock immediate opportunities to construct silicon-integrated, telecommunications-band quantum information networks,” said the study.

Simmons, who is the university’s Canada Research Chair in silicon quantum technologies, said the main challenge with quantum computing was being able to send information to and from qubits.

“People have worked with spin qubits, or defects, in silicon before,” Simmons said. “And people have worked with photon qubits in silicon before. But nobody’s brought them together like this.”

Lead author Daniel Higginbottom called the breakthrough “immediately promising” because researchers achieved what was considered impossible by combining two known but parallel fields.

Silicon defects were extensively studied from the 1970s through the ’90s while quantum physics has been researched for decades, said Higginbottom, who is a post-doctoral fellow at the university’s physics department.

“For the longest time people didn’t see any potential for optical technology in silicon defects. But we’ve really pioneered revisiting these and have found something with applications in quantum technology that’s certainly remarkable.”

Although in an embryonic stage, Simmons said quantum computing is the rock ‘n’ roll future of computers that can solve anything from simple algebra problems to complex pharmaceutical equations or formulas that unlock deep mysteries of space.

“We’re going to be limited by our imaginations at this stage. What’s really going to take off is really far outside our predictive capabilities as humans.”

The advantage of using silicon chips is that they are widely available, understood and have a giant manufacturing base, she said.

“We can really get it working and we should be able to move more quickly and hopefully bring that capability mainstream much faster.”

Some physicists predict quantum computers will become mainstream in about two decades, although Simmons said she thinks it will be much sooner.

In the 1950s, people thought the technology behind transistors was mainly going to be used for hearing aids, she said. No one then predicted that the physics behind a transistor could be applied to Facebook or Google, she added.

“So, we’ll have to see how quantum technology plays out over decades in terms of what applications really do resonate with the public,” she said. “But there is going to be a lot because people are creative, and these are fundamentally very powerful tools that we’re unlocking.”

Samsung’s Galaxy Unpacked event: start time and how to watch – The Verge

Published

 on


Samsung Galaxy Unpacked is set to begin on Wednesday, August 10th.

Leading up to the event, Samsung has left us with breadcrumbs about what they’re going to announce at their Galaxy Unpacked event. Leaks and other clues have revealed that Samsung may be announcing an updated foldable to match last year’s announcement and release.

We also have a guess that there might be some new Galaxy Watches to announce as Samsung released a reservation for a trade-in for the Galaxy smartphone, smartwatch, and earbuds.

When does the Samsung Galaxy Unpacked event take place?

The Samsung Galaxy event is set to take place on Wednesday, August 10th, 2022, at 6AM PT / 9AM ET.

Where can I watch the Samsung Galaxy Unpacked event?

We will have the livestream video embedded up top, so you can stick around here to watch when it begins. Otherwise, you can tune in to the Galaxy Unpacked livestream at Samsung.com, Samsung’s Newsroom, and Samsung’s YouTube channel.

We here at The Verge will also be covering the event. Be sure to follow @verge on Twitter and @verge on Instagram for live updates and other Samsung news.

Samsung Galaxy Unpacked: How to watch Samsung announce its latest foldable phones – ZDNet

Published

 on

On Wednesday, Samsung is expected to announce new foldable phones, wireless earbuds, and a new Galaxy Watch. If all of the leaks and rumors are true, that means we’ll see the Galaxy Z Fold 4, Z Flip 4, Buds 2 Pro and the Galaxy Watch 5 (and maybe even a Pro model). 

Who knows, Samsung could have other products lined up for announcement. We simply won’t know what all it entails until the livestream ends. 

When is Samsung Galaxy Unpacked?

The event kicks off early Wednesday, Aug. 10, with the livestream starting at 9 a.m. ET/6 a.m. PT. There isn’t an in-person element to the event as companies continue to stick to a virtual-only approach for product announcements. 

Here are the different international times for your reference:

  • New York: 9 a.m. ET
  • San Francisco: 6 a.m. PT
  • London: 2 p.m. GMT
  • Berlin: 3 p.m. CET
  • Mumbai: 9:30 p.m. IT
  • Tokyo: 11 a.m. JT Jan. 15
  • Sydney: 1 a.m. AEDT Jan. 15

How to what Samsung Galaxy Unpacked

If you want to tune in and watch the announcements as they’re made, then you’re in luck. Samsung is broadcasting the livestream across several different platforms. Here’s everywhere you can watch the official stream:

What to expect from Samsung Galaxy Unpacked

Samsung itself has dropped some major hints about what to expect from the announcement. Certainly, there are new foldable phones — likely the Z Fold 4 and Z Flip 4 — on tap to be announced. 

In addition to the new phones, Samsung’s Galaxy Watch5 appears set to get an upgrade, with a new Watch5 Pro model, which early leaks indicate will be more rugged and more of a competitor to Garmin’s line of smartwatches. 

Finally, Samsung’s Galaxy Buds Pro appear primed for an upgrade with the Buds 2 Pro adding new active noise cancellation features and a refreshed design to the company’s completely wireless earbuds. 

We’ll have full event coverage as Samsung’s latest Galaxy Unpacked event kicks off bright and early on Wednesday, Aug. 10.

Apple might bring back Status Bar battery percentage with iOS 16 – MobileSyrup

Published

 on


In classic Apple fashion, the tech giant could bring back a feature it never should have removed.

In iOS 16 beta 5, the battery percentage indicator in the ‘Status Bar’ has returned. The tech giant nixed the functionality alongside the release of the iPhone X back in 2017. Though it’s been possible to view battery life in the iPhone’s settings, glancing down at your device and seeing a specific number in the status bar is far more convenient.

According to 9to5Mac, reading the percentage in the latest version of iOS 16’s beta is as simple as navigating to ‘Settings,’ selecting ‘Battery’ and then turning on a new Battery Percentage option. There’s a possibility that the feature could be enabled by default when the public version of iOS 16 releases this September. When I downloaded iOS 16 beta 5 on my iPhone 13 Pro, the option to add a battery percentage (seen in the photo above) appeared under the Battery section of the settings app.

The percentage is visible while charging, in low-power mode and during general use, as long as the feature has been enabled. Interestingly, 9to5Mac says that the option to add the battery percentage to the iPhone XR, iPhone 11, iPhone 12 mini and iPhone 13 mini is not available in iOS 16 beta 5.

Given how perplexing it was that Apple ditched the battery percentage option in the first place, it’s great to see it finally returning. That said, it’s difficult to celebrate functionality that shouldn’t have been gotten rid of in the first place.

Still, it looks like the battery percentage indicator is coming back, and it seems Apple has finally listened to the criticism surrounding its removal.
