(法新社華盛頓4日電) IBM公司今天開放量 子電腦處理器,歡迎各界試用具備能力且速度大幅提升 的新型電腦。IBM表示,任何人都可藉由連上與IBM雲相 連的網站,在運算平台上進行實驗。 這個雲端運算系統能讓使用者探索, 科學家說這或許能解決現在超級電腦不可能解決的問題 。

IBM研究中心資深副總裁兼主任克利希納(Arvind Krishna)表示:「這一刻代表量子雲端運算誕生。」 他指出:「量子電腦與現在的電腦非常不同,不只 外觀和材質,更重要的是功能。量子運算已逐步實現, 且會讓計算遠超越用現有電腦所能想像的。」

量子運算雖剛起步,科學家相信可帶來人工智慧的 長足進展、改變材料科學,並允許研究或分析比當今最 強大電腦能處理更大量的資料。 IBM表示這部放在公司華森研究中心的量子處理器 ,是打造擁有更多潛力通用量子電腦的第一步。

    引完收唔到科,現在已經係咁!

看看美帝由 2000-2008 做的事,令世界陷入更混亂當中,多得共和黨薯仔同療吧

IBM allow free access to quantum processor online

IBM has made a functioning quantum processor available to the public over the internet.

Quantum computing is widely seen as an evolution of computer technology, which may allow for much faster calculations than today's machines.

The technology is still in its infancy, but one expert said it was a "small step" towards a useful quantum computer.

IBM said it hoped to see processors up to 20 times larger in the next decade.

Traditional computers process all their information using bits - information stored in tiny transistors that can either be on or off - interpreted as values of one and zero.

Quantum computing instead takes advantage of a mechanic called superpositioning that allows quantum bits - or "qubits" - to have values of one, zero, or both at the same time.

Researchers believe this core difference will eventually lead to powerful devices with processing power that will exceed the limits of classic computers.

IBM's quantum processor is located in its TJ Watson Research Centre in New York. Quantum processors are notoriously sensitive, so it is being kept at supercooled temperatures in a cryogenic refrigerator.

It has just five qubits that can be manipulated, but the company expects processors of 50-100 qubits to emerge within the next decade. General-purpose machines, which IBM calls "universal" quantum computers, will eventually use more than 100,000 qubits.

IBM's cloud solution allows users to drag and drop logic gates - a core principle of processors - on to the individual qubits to form algorithms or experiments. Those can then be sent to a simulator, or added to a queue for the real quantum processor to work on.

People wishing to access the processors must request an invitation through a web form that asks for a user's institution details and level of computing experience.

A spokesman for IBM said the invite system was to prevent bots from swarming the system, and told the BBC that anyone would be granted access regardless of experience.

The complexity of quantum computing means that most users are likely to have a basic background in the subject.

"IBM has made a small but very significant step towards a useful quantum computer," said Chris Ford, Professor of Quantum Electronics at Cambridge University.

"This will only be useful for experts who know what they are doing, but the very idea that it's available to all may bring quantum computing to the attention of the general public, and encourage more people to be interested in how physics makes this new form of computing possible."

The potential power of quantum computing to perform advanced calculations is also a concern for the security industry, as it may make it possible to easily crack existing encryption methods.

Current security standards rely on the extreme complexity of encryption - something advanced quantum processing may be able to handle.

The US National Institute of Standards and Technology has announced it will hold a public competition for new encryption standards that will be more difficult to crack - hoping for a quantum-proof standard by 2023.
