Tiffany launches 2019 advent limited calendar - Tiffany launches $ 112,000 Limited Advent Calendar, costing $ 112,000: As the Christmas season approaches, brands launch dozens of luxury advent calendars filled with toys, beauty products, sweets, and even beer.

But luxury jeweler Tiffany & Co has cast an imposing and opulent shadow on them all with its $ 112,000 Ultimate Advent Calendar.
According to Tiffany's website, only four of the calendars will be available.

The packages will arrive as a £ 355 delivery, before being hand-coupled through what Tiffany & Co calls their "White Glove Service."
The four-foot-tall display was designed as a replica of the company's Fifth Avenue flagship store in New York. Behind each of the 24 doors and drawers is a glowing Tiffany product.

The website describes in-house gifts ranging from the company's most beloved products to some "witty everyday items", including a "paper" cup, clothespin and a harmonica. sterling silver.

In addition to items from the Everyday Objects range, Tiffany's exclusive blue boxes will also feature diamond, platinum and gold jewelry, as well as perfume, an ornament, a keychain and a candle.

The Advent Calendar is just one of 12 gifts and experiences selected from Tiffany & Co's holiday catalog
The Very Very Tiffany Holiday Collection also includes a solid sterling silver greenhouse, a custom made Tiffany Blue motorcycle and an 11 day safari in Kenya that comes with a personalized TiffanyxGlobe-Trotter luggage set for travel.

Has Google really unlocked quantum supremacy? Not so fast, says IBM

Last month, a leaked Google research article suggested a significant quantum breakthrough. IBM's research team now suggests that the statement was a bit premature.

Last month, a research article published briefly on a NASA website, and since being deleted, suggested that Google had achieved quantum supremacy. This means that their quantum computer could, in theory, make calculations that are impossible even for the highest performing supercomputers in the world.

The paper claimed that Google's 53-bit quantum system had taken three minutes and 20 seconds to perform a calculation that would have taken the most advanced classic computers in the world 10,000 years to complete.

But now, IBM's research shows that a classic system can do the same task in two and a half days, "and with much more fidelity." What's more: According to researchers, this is the worst-case estimate.

This is not a case for quantum supremacy. Google's mistake, said IBM staff in a blog post, was to underestimate the resources of classic computers, and especially their data storage capacity.

"When comparing (Google) to the classic," they said, "they (...) did not take into account the abundant disk storage." IBM, therefore, proceeded to simulate the same task using primary and secondary storage to extend the reach of supercomputers.

In addition to a memory hierarchy, IBM has introduced a palette of performance-enhancing methods that can further reduce the amount of space required to complete the task and, in turn, the time it takes to complete. "It is important to leverage all of these capabilities when comparing the quantum with the classical," said his research team.

All in all, the IBM team discovered that simulating a 53-qubit circuit required 64 PB of disk space, and for 54-qubit circuits, 128 PB were required. All of which is within the capacity of 250 PB of a supercomputer.

"Google's experiment is (...) displaying cutting-edge door fidelity on a 53-qubit device," the researchers concluded, "but it must not be viewed as proof that quantum computers are 'supreme'. 'about classic computers ".

In addition, they urged the public to take any news of "quantum supremacy" with a pinch of salt, insisting that quantum computers will work in concert with classic computers in the future, rather than reigning over them.

Quantum computing revenue is expected to increase from $ 1.9 billion in 2023 to $ 8 billion by 2027, and will have countless applications in physics, chemistry, artificial intelligence and energy, among many others. But it could still be a while before quantum devices can outperform classic computers.
