📰 First entanglement between a photon and a hole spin qubit in silicon – Techno-Science.net

The spins of electrons or their vacancies (holes) are promising candidates for encoding quantum information because they can be isolated in silicon quantum dots using technology compatible with industrial microelectronics processes.

Unlike electron spins, hole spins can be manipulated by an electric field. They actually show a strong “spin-orbit interaction”, which means that the displacement of a hole induced by an electric field is coupled to the state of the spin via the “spin-orbit interaction”. Researchers at Irig have for the first time succeeded in using this effect to coherently couple a hole spin in silicon to a microwave photon.

Vibrations and hole spin resonance at the same frequency

How did you do it? “In the channel of a silicon transistor manufactured at CEA-Leti, we enclosed a hole between two gates at a very low temperature (T = 10 mK) and then connected the end of a superconducting microwave resonator to one of the two gates. When a photon is trapped in the resonator, it induces electric field fluctuations that are delivered directly to the gate of the transistor, causing the hole in the transistor channel to oscillate. works when the frequency of these oscillations is exactly the same as the resonant frequency of the spin of the hole,” explains Cécile Xinquing Yu, PhD student at Irig.
Coherently coupling a microwave photon and a hole spin qubit in silicon: Irig researchers have succeeded. This result paves the way to remote two-spin entanglement using a microwave photon as the mediator of the quantum interaction. This could be beneficial for the realization of quantum processors based on silicon spin qubits. In fact, in this configuration, the photon is absorbed to change the spin from the ↓ state to the ↑ state, and then re-emitted by changing the spin of the hole from the ↑ state to the ↓ state, and so on. The rate of this “absorption/emission” is directly related to the strength of the coupling between the spin and the photon.

By varying the orientation of the magnetic field, the researchers tracked this absorption/emission rate. The results obtained clearly show, compared to a theoretical model, that the spin and the photon are entangled thanks to the spin-orbit interaction. Note that the strongest coupling observed converts the photon into a spin excitation in less than three nanoseconds! “These results therefore show that hole spin qubits and microwave photons trapped in silicon transistors can talk to each other very quickly, much faster than their coherence time,” says Romain Maurand, physicist at Irig. This makes it possible to exchange a photon between multiple spins to achieve long-range spin-spin entanglement, which could be beneficial for the fabrication of quantum processors based on silicon spin qubits.

Good morning,

I recently received a refurbished iPhone with an iCloud lock. I’ve tried bypassing Activation Lock, but all efforts have been in vain. Does anyone know how this works? Please help me!

If the above scenario sounds familiar to you or if you are facing something similar and need a solution then you are in the right place. This article will guide you through four powerful techniques to unlock iCloud locked phone. So let’s start.

What does locked iCloud mean?

As part of the setup process for setting up an iPhone, Apple requires end users To or sign in with an Apple ID in order to use its services. This will automatically lock the device with the proper credentials, meaning it’s iCloud locked. As long as you (or the owner, if the device is used) do not provide these details, an intruder cannot use or tamper with Apple services on the device.

Is it possible to unlock an iCloud locked iPhone?

Surely! iOS users can easily unlock an iCloud locked iPhone from their home. If you remember your Apple ID, you can use your Apple ID and password to unlock Activation Lock. You can contact the previous owner to remove your device from their iCloud account if you are using a used device.

If you can’t remember your Apple ID and password and can’t contact the previous owner, you need to use third-party software to bypass Activation Lock. You may be wondering how this is possible, especially if you are unfamiliar with information technology.

Social Show 10 – Meet Social Mimi – IsartaTikTok coach Geneuviève Thibault shares her advice on the 10th episode of the social show

March 30, 2023

In the 10th episode of The Social Show, the content creation podcast hosted by Francis Jette and produced in collaboration with Isarta, we discover the atypical journey of the tiktokeuse Geneuviève Thibault (@socialmimi) while you learn a thousand and one handy tips to shine on TikTok.

With videos garnering 2.7 million “likes”, Geneuviève Thibault has carved an enviable place for himself as a coach and supporter for companies looking to promote their brand on the Chinese platform. In an interview, however, we learn that the 48-year-old TikTokeuse has had a career full of detours and twists and turns: she was an engineer at SNC-Lavalin, founded an online shop for baby products and was an entrepreneur in Mexico.

[J’ai découvert TikTok] while attending the Social Media Marketing World conference in San Diego in March 2020. I listened to a presentation by a woman named Rachel Petersen who immediately got me hooked on TikTok. She was so passionate. I came back to Montreal and immediately installed the application. A few days later everything was closed due to the pandemic…”

At this point in history, the engineer-turned-entrepreneur had already developed strong community management skills and was hosting a forums site for her online store.

From the beginning [de mon parcours entrepreneurial]I had the idea that before you sell anything, you have to build a community.”

Three years later, the Sociale Mimi community has over 160,000 followers on TikTok.

The power of commenting and interacting with other users shouldn’t be underestimated, she reminds us. A community is not a one-way street. So if you’re on TikTok and not following or interacting with anyone, you’re sending yourself a signal that you’re not there for the right reasons. First you need to make a human connection; the commercial or transactional aspect remains secondary. »

No marketing plan or release schedule

Since her debut on TikTok, the content creator has encouraged an intuitive approach that allows spontaneity to flow.

The marketing folks would certainly smack me on the back, but I don’t have a concrete marketing plan or release schedule. I am a girl of feelings. My strength is taking chances. I am able to add a creative twist to an already existing trend. »

Throughout the interview, we understand that Geneuviève Thibault is a workaholic – she multiplies takes and edits at will. In addition, the quality of the many transition, dance, and tutorial videos is a testament to that. She is also very organized – she archives and categorizes her “sounds” by favorites in advance, in anticipation of an inspiring idea coming to her or a client’s mind.

Some people sometimes have white page syndrome, she notes. You can easily waste an hour or two trying to come up with an idea, while not wasting time recording sounds in advance and coming back to them when you have a flash. It’s super efficient. »

Video Games | The 2023 edition of the E3 fair is canceled – La Presse

(New York) The 2023 edition of the American video game show E3, one of the most important world events in the industry, has been canceled, organizers announced on Thursday, leaving doubts about the next editions.

Posted at 10:52 p.m

share

Events company ReedPop, responsible for running the show through Entertainment Software Association (ESA), said on E3’s official website that the cancellation affected the entire program, in-person or online, originally scheduled for June 13-16 was planned.

ReedPop and ESA “will be considering the future of E3,” the two parties jointly stated.

The Electronic Entertainment Expo was established in Los Angeles (California) in 1995 and brings together the main players in the video game industry every year.

E3 did not take place in 2020 due to the pandemic before returning in fully virtual form the following year and being put on hold again in 2022.

The organizers have not publicly communicated the reasons for their decision.

However, in an email sent by ESA to its members and forwarded by the specialist website IGN, the organization explained that the 2023 edition “did not generate the interest necessary” to bring to life a show “which has the size, power and… Realized size would impact our industry.

For more than ten years, the E3 has been considered to be losing momentum, on the one hand because the giants of the industry are presenting their innovations there less and less frequently.

Large console manufacturers and game publishers are increasingly favoring custom launches over these trade shows, often choosing to host their own events.

Xbox, Sony, Nintendo or even Ubisoft had all decided not to go to E3 this year before the cancellation.

Other major events have nevertheless managed to return face to face after the pandemic, notably Paris Games Week, which attracted 150,000 visitors at the Porte de Versailles in early November, or the Tokyo Game Show, attended by almost 140,000 people , in Sep 2022.

T. rex had lips, concludes a study that shakes our perceptions

Animals like T. rex and velociraptors, theropod dinosaurs, most likely had some kind of lips, soft tissues that covered their mouths to protect their teeth, explains Agence France-Presse Thomas Cullen, one of the authors of this study published in the journal Science(New window). (in English)

This is a departure from many previous hypotheses that said they looked more like crocodiles, with teeth that were visible when their mouths were closed and no lips, adds this professor of paleobiology at Auburn University in ‘Alabama.

We’re talking about thin lips, similar to those of lizards or Komodo dragons, says one of the study’s co-authors, Derek Larson, researcher and manager of the Royal British Columbia Museum’s paleontological collection.

“As these results become more widespread in the scientific community and in the public sphere, I think our depictions of T. rex will change going forward. »

— A quote from Derek Larson, Royal BC Museum

If the question isn’t fully resolved, starting in 2014, researchers studied a group of theropods from multiple museums to arrive at this new conclusion.

For example, they compared the wear and tear on the enamel of dinosaurs and crocodiles, the living animals closest to these theropods.

Tooth enamel needs to stay hydrated to stay healthy, says Thomas Cullen. If left exposed to air for too long, it becomes friable and has a greater chance of cracking or contracting disease.

According to the paleobiologist, the enamel on the outer part of the teeth of living crocodiles wears away faster than the inner part because they don’t have lips.

When we looked at the thickness of the enamel on the inside and outside of the teeth of large tyrannosaurs, they didn’t show that kind of crocodile-like configuration, he continues.

They depict a model approaching animals with lips, Thomas Cullen suggests. The thickness of their enamel is the same on the outside and inside.

Profile of a T Rex.

Derek Larson says the color of dinosaur lips and skin is still being researched.

The researchers also wanted to know if T. rex’s teeth might have simply been too big for its mouth by comparing them to many living lipped lizards.

Some monitor lizards have absolutely huge teeth today, Cullen said. It seems almost unbelievable that these teeth could be completely covered by lips, and yet they are.

And that’s what we found out […] This scale ratio is nearly identical for theropod dinosaurs.

When perception changes

After studying the way dinosaurs lived and evolved, we began to focus more and more on their appearance. Other methods will no doubt be able to verify these already fairly solid results, says paleontologist François Therrien of Alberta’s Royal Tyrrell Museum.

For example, it was hard to imagine that some dinosaurs had feathers, and yet. The game has changed since the first discoveries of feathered dinosaurs in the 1990s, he says.

What are the implications for the depiction of T. rex and velociraptors in popular culture?

While Thomas Cullen acknowledges that the Jurassic Park films managed to stay true to what was known about dinosaurs at the time, he says attempts to faithfully depict theropods have since gone haywire.

You can now buy a futuristic caravan from $360,000 – Le Journal de Québec

More than 10 years after the announcement, a New Zealand company is launching a luxury caravan starting at US$360,000 ($268,500).

The price can of course increase with options and requires a deposit of US$6,300 (CA$8,520) according to the Robb Report.

The caravan, a Romotow T8 by W2, is unique, featuring a small cab that slides out like a USB stick when the vehicle is stationary, and a frame that transforms into a sheltered patio.

The modern and luxurious living space is actually a mini house, with a kitchenette and dining room, bathroom and separate toilet, and a bedroom that can be booked with two single beds or a double bed. It is also possible to add a pull-out double bed in the living room.

Other options are available such as B. a wall-mounted TV, an outdoor projector system and a multi-zone sound system.

The hydraulic rotation system, as well as the various options of the caravan, are powered by a lithium battery, accompanied by roof-mounted solar panels.

Built by ACM Motorhomes, the 30.5-foot trailer has stayed true to the original images, despite the criticism the project has received throughout the process.

The first computer images were actually proposed in 2012, the physical prototype was released in 2018 and finally the caravan was born in 2023.
