Google’s new quantum computer is '100 million times faster than your PC'
Google and Nasa have been working on a lightning-fast quantum computer that is 3,600 times faster than a supercomputer at solving complex problems

Has Google won the race to build the world’s first commercial quantum computer?

The technology company’s artificial intelligence lab believe they may finally have proof that their opinion-dividing quantum computer actually works.

Google and Nasa announced they were collaborating on the D-Wave X2 quantum computer, which they say is 100 million times faster than a conventional computer chip, in 2013. It can answer certain algorithms in seconds rather than years.

Google director of engineering, Hartmut Neven, said: “For a specific, carefully crafted proof-of-concept problem we achieve a 100-million-fold speed-up.”

In a blog post he added: “We found that for problem instances involving nearly 1,000 binary variables, quantum annealing significantly outperforms its classical counterpart, simulated annealing. It is more than 108 times faster than simulated annealing running on a single core.

“We also compared the quantum hardware to another algorithm called Quantum Monte Carlo. This is a method designed to emulate the behaviour of quantum systems, but it runs on conventional processors.

“While the scaling with size between these two methods is comparable, they are again separated by a large factor sometimes as high as 108.”

However, Matthias Troyer of the Swiss Federal Institute of Technology in Zurich said he wasn’t convinced.



“You need to read the fine print,” he told New Scientist. “This is 108 times faster than some specific classical algorithm on problems designed to be very hard for that algorithm but easy for D-Wave.”

Hemet does admit in his blog post that other algorithms can currently beat D-wave but says Google expect “those methods will soon become ineffective”.

Ak harap dpt idop lg time manusia bjaya mcipta teknologi yg mampu mlengkok ruang angkasa...supaya pjalanan dr x ke y dpt disibgkatkan... Supaya manusia mampu bpindah rendah dari Satu tempat ke dunia lain dlm skelip mata Mcm pintu doremon tu...

begitu berilmiah sekali thread bangkem ni

maknanya dark energy dengan dark matter ni..saling berlawanan kan?

Dlm byk2 thread, aku rasa kat thread ni ada nampak hebatnya bangkem

dengan penemuan ni adakah bermakna selangkah ke arah pengembaraan merentas masa?

Gravity drags time. So time akan berubah mengikut gravity. 1 saat di bumi tak sama dgn 1 saat di black hole sebb gravity black hole sgt tinggi.

jadinya aku ingatkan gravity ni terhasil sebab putaran bebola besi dlm bumi,  (teras bumi)

eisten overwrite teori newton..sebelum ni newton ckp bumi yg tarik as graviti.. tp sebenarnya ruang angkasa bend.

bak kata einstein:

aku nk like jugak

Ha_Neul

"melengkungkan ruang angkasa" .. so ruang angkasa ni macam kain la pulak.. letak bola atas dia jadi kain tu melengkung.. teori ni memang menarik tapi kenapa fabrik tu tak melengkung ke arah lain? macam ada satu graviti lain yg bertindak ke atas bola tu, bukan bola tu sendiri yg mengakibatkan graviti.. saintis ni pon pandai mengelat jugak bila something tak boleh explain diorang acah2 paham, bila dalam kebuntuan macam mana universe ni boleh hold together, dark matter jadi kambing itam... tak ubah macam theists gak.. bila malas nak pikir - kuasa Tuhan

The first-ever detection of gravitational waves, which scientists could announce Thursday, would open a new window on the universe and its most violent phenomena

These waves are produced by disturbances in the fabric of space and time when a massive object moves, like a black hole or a neutron star.

Einstein theorized that they would appear like ripples in a pond that form when a stone is thrown in the water, or like a net that bows under the weight of an object placed within - with the net serving as a metaphor for the bending of space-time.
