Research on quantum computers has been going on for several decades. Phases with many important breakthroughs were repeatedly replaced by periods in which things did not seem to be progressing at all. In the past three years, however, the subject has once again gained considerable momentum. Experts report that more progress was made during this period than in all previous years. In addition, researchers assume that a change of time is imminent.

For the first time, all of the components required to build a powerful quantum computer are actually available. The challenge now is to assemble these individual parts into a functioning system. For this purpose, Google has set up its own research campus in the US state of California. In addition to the classic research facilities, a quantum data center and its own chip production facility are also being built there. The goal: A commercially usable quantum computer is to be built by 2029.

Google wants to massively increase the number of qubits

The schedule doesn’t sound particularly ambitious at first. After all, IBM has according to its own information . The companies are therefore more likely to view their engagement as a kind of research. Because the development of quantum computers actually promises the opposite: Because the arithmetic units called qubits can not only assume the state 0 or 1, but also combine both states, several calculations can be carried out in parallel. In theory, this massively reduces the time required. In practice, however, the quantum computers available to date only have a three-digit number of qubits.

That number is still too small to meet the hopes associated with the technology. already developed a commercial quantum computer . But this is more of a somewhat creative communication. Because the IBM computer is used by some companies. In fact, it is still nowhere near as powerful as conventional supercomputers.

There are still some problems to be solved

Google therefore wants to go a massive step further and install at least one million qubits in the planned commercial quantum computer. However, the sheer mass of computing units alone is not yet decisive. Rather, the challenge for the researchers is to ensure that the qubits remain in the desired quantum state for as long as possible. So far, the devices have been very susceptible to interference in this regard. This in turn can lead to arithmetic operations being carried out incorrectly or even having to be terminated.

Google is therefore working on various approaches to ensure that errors are corrected automatically. The research work required for this is likely to keep the company busy for a few more years. Against this background, the target year 2029 sounds quite ambitious again. At least the company has now announced that it will work with a number of companies and research institutions to develop and test application scenarios at an early stage

Apple Watch owners had to deal with the issue of the electronic SIM card relatively early. A few years ago, anyone who wanted to fully use the Apple Watch with the red crown could not avoid activating the virtual SIM card. If telecom customers initially benefited from the new SIM card, the eSIM (embedded SIM) was gradually further integrated into the market. In this article, we want to take a closer look at the possibilities that eSIM reveals and how the SIM card of the future will work.

eSIM- This is how the soldered SIM card works

The eSIM was introduced seven years ago. One of the pioneers here is Apple. At that time, the group had to fight again with a small shit storm. “If it is not bad enough that the batteries in the iPhone and Co are firmly glued, it can now continue with the SIM card”, so the possible tenor. Seven years later, the eSIM is no longer uncommon, especially in smartphones in the upper price categories. Increasingly, use is also expected to shift to the middle class sector. The advantages of the eSIM are obvious. The mere fact that no slot for the SIM card is required not only allows greater device design leeway, but also makes the device less prone to mechanical defects, according to the manufacturers.

When an eSIM-supported device is delivered, the SIM card is already firmly inside as a component. As a result, the data, which can also be found on conventional SIM cards, is simply downloaded over the Internet. That was the big magic. According to the global industry association of mobile communications providers (GSMA), by 2025 just under a third l of the smartphones used around the world should be equipped with an eSIm. Although the providers are helped and mail can be avoided, the support of the eSim is still progressing a bit sluggishly. With a majority of the mobile phone providers and also with smart prepaid card tariffs, the embedded SIM cards can often even be exchanged free of charge or requested in addition. A creeping revolution that is worthwhile. Why? This is shown by a look at the possibilities of the virtual SIM card.

The eSIM can enable many functions in the future

The eSIM not only makes it easier to change devices or mobile network providers, it can also save data, such as electronic ID cards. Since more and more devices are able to establish a connection to the Internet, eSIMs are also useful where the module with the corresponding kit group is not so easy to reach, so changing the SIM card is quite difficult. Larger industrial plants but also household appliances or motor vehicles would be conceivable. The soldered-on SIM card is then much easier to use. With a large number of IoT devices (internet of things), the eSIM is now indispensable. As a result, the classic SIM card has increasingly become obsolete. The electronic driver’s license or token for locking systems are further application scenarios.

Risk of SIM swapping

However, the eSIM technology also has a bitter aftertaste. As with many innovations that can be realized via the Internet, hackers are also on board. A very recent phenomenon is so-called SIM swapping. Here, hackers pretend to be their victims and use previously spied data to commit theft of the mobile phone number. Why steal the cell phone number? Because online banking accounts, shopping profiles and some other sensitive data are often linked to this. The hackers either get the data on the victims via social networks (social engineering), buy it on the DarkNet or use phishing emails. If the required data is available, the customer center of the mobile phone provider is informed that either the mobile phone, including SIM card have been lost or the existing contract is terminated and a new one with phone number portability is to be concluded. In both cases the number would almost be gone.

However, with a normal SIM card, the hackers would first have to wait for the post while the eSIM is activated via the Internet. The post with the conventional SIM can possibly result in an additional trace. How to protect yourself is explained The post with the conventional SIM can possibly result in an additional trace.

In this case, the mobile network providers are obliged to close this security gap.

As anticipated, WhatsApp is working on a new mode that will offer support to connect up to four devices simultaneously, including the iPad.This was confirmed by the WABetainfo portal , known for sharing the news of the messaging service, after having spoken with the executive director of Facebook, Mark Zuckerberg , and with the executive director of WhatsApp, Will Cathcart , about the news that will soon reach the application .

Multi-device support is a function in which the company has been working for a long time and will allow the account to be used on a computer other than the main mobile, without the need to have an active internet connection on it.

Zuckerberg stressed that it was “a great technological challenge” and that they have already solved it and that they hope to launch it soon. Specific,Cathcart confirmed that the multi-device support will hit a public beta “in a month or two.”

With multi-device support, messages will maintain end-to-end encryption, and users will be able to use the same account on up to four devices, including the iPad.

Another new feature announced is a new mode for temporary messages. Currently it is possible to activate the function that allows setting a time frame so that the messages of a certain chat disappear automatically.

The new mode, if activated, will implement temporary messages in all chats at once, which will make the WhatsApp experience “ephemeral”, as Zuckerberg stressed, since all messages will automatically disappear after seven days.

In relation to the content that disappears, there will also be another function, called “watch once”, which will automatically delete the photos and videos when the receiver has seen them, although the possibility of taking screenshots will be maintained.

The temporary message mode and the “watch once” feature will soon be coming to beta app participants. The company hopes that these developments will make messages “more private and secure.”

The functions of users who have not accepted its new conditions of use will not be limited

A few days ago, the platform confirmed that the functions of users who have not accepted its new conditions of use, which came into effect on May 15, will not be limited .

It is a change of course with respect to the company’s decision until recently when it announced that those who did not accept the conditions would see the service progressively limited.

The company now published that anticipated a few weeks ago by company spokespersons, in its Help Center. In this way, in writing, he made it official that ” the account of any user will not be eliminated or access to WhatsApp functions will be removed on May 15 due to this update “, in which the changes in the conditions of service have been included. .

The new decision assumes that there is no consequence for not accepting the new Conditions and Privacy policy launched in the update available from May 15, at least at this time.

The company assured that ” most of the users who saw the update accepted it “, and indicates that they will continue to show a notification in the application to those users who have not approved the new conditions.
