IBM will sell 50-qubit universal quantum computer “in the next few years”

 

Kopitiam Bot

IBM has solved most of the science behind quantum computing. Time to make some money. 

IBM will build and sell commercial 50-qubit universal quantum computers, dubbed IBM Q, "in the next few years." No word on pricing just yet, but I wouldn't expect much change from $15 million—the cost of a non-universal D-Wave quantum computer.In other news, IBM has also opened up an API (sample code available on Github) that gives developers easier access to the five-qubit quantum computer currently connected to the IBM cloud. Later in the year IBM will release a full SDK, further simplifying the process of building quantum software.
You can't actually do much useful computation with five qubits, mind you, but fortunately IBM also has news there: the company's quantum simulator can now simulate up to 20 qubits. The idea is that developers should start thinking about potential 20-qubit quantum scenarios now, so they're ready to be deployed when IBM builds the actual hardware.

Is D-Wave’s quantum processor really 10⁸ times faster than a normal computer?
Speaking of hardware, it seems IBM has accelerated its universal quantum computing roadmap somewhat. In May last year IBM said it would like to build a 50-qubit computer "in the next decade." Now we're down to "the next few years."
IBM has also fleshed out its quantum computing roadmap a little, providing some guidance on how it will actually build a universal 50-qubit computer:

IBM’s roadmap to scale to practical quantum computers is based on a holistic approach to advancing all parts of the system. IBM will leverage its deep expertise in superconducting qubits, complex high performance system integration, and scalable nanofabrication processes from the semiconductor industry to help advance the quantum mechanical capabilities.
Other than D-Wave, IBM doesn't have much competition in the quantum computing space—and as we've explained in the past, both companies appear to be approaching quantum computing quite differently. IBM has set its sights on building a true universal quantum computer, which can be used to solve any quantum algorithm under the sun. D-Wave seems more focused on scaling up the number of qubits and ensuring its system can integrate easily with classical computers, but not ensuring its qubits are actually qubits.

While exact pricing, availability, and specs are still a long way off, it's fairly safe to assume that IBM's quantum computers will be about the same price as a D-Wave (~$15 million) or perhaps a little dearer. Both systems are fundamentally the same thing: a fancy chip inside a box that contains a multi-stage dilution refrigerator from a company like BlueFors.

Dilution refrigerators take about 24 hours to cool down, but they can then keep the chip at close-to-absolute-zero (~5mK, -273.145°C)—a prerequisite for current quantum computing chips—almost indefinitely.

And finally, a random factoid: the photo on the right shows me standing on a ladder next to one of IBM's dilution refrigerators at IBM Research headquarters in upstate New York back in 2013.

How to Blue Verified Facebook Page Method By Tech 4u Hub

Facebook Blue verify badge Method With Documents . 

Bohot Log bolenge method same hai ye tw pehle bhi dekha hai dusre groups mai lekin ek baat kehna chahunga ap logo ko Method legal hai 

or ye luck per hota hai k apka page verify hota hai Mera kaam hai apko Documents provide krna saath hi Smjhana kis thra verify hote hai pages (Y) 

Step by Step btaonga . 

1 : Blue badge site banana se kabhi nahi milega ! 

2 : Blue badge k liye Public figure Category Lazmi rhkna . 

3 : Public Figure mai apse Facebook wale konse Documents mangte hai ! 

4 : Driverts license - Passport - Birth certificate - Articles . 

Ab apko krna kea hai ? 

Sab se Pehle tw thori mehnat kar k apko kisi se USA account banwana padega ussi ki ip se wo is liye q k agar ap log Proxy laga bhi lo :( tw ap jo page banaoge 

wo Verify k liye allow nahi karenge select page ki jaga kuch nahi ayega is liye apko ek USA account banwa k uhne kehna hoga k ek page create karde or unse wo account lelena ap 

uske bad ye dono form khule ap agar apne jo iD USA se banai hai us mai ye dono form open hote dikh jayegi baki acocunts per beshak try karlena nahi open hona :3 so jo btaya woi karna ap log wrna bad mai ap logo ne yehi kehna hota bhai fake method btaya lol .

Ek or main cheez apko ye bhi btate chalun k jis name se apne page banaya hai apko ussi name se web bhi banani hogi q k jab ap verification form mai info dalte apse web bhi mangta hai so apne baare mai likh dena or articles likh dena unique or web bana k wahan link dal dena ! 

SSL laga hona chye domain mai kahin log smjhte fb wale chu**** hai wo log 3rd class domain ko bhi accept karenge bhai wo FB hai koi choti moti company nahi . 

Documents Apko dun isse pehle bta dun k documents ap logo k pass already hai sample bta deta hun k kis thra k documents work karte bhai . 

Passport jis bhai k pass passport ho Wo scan karle ! 

is thra -> http://prntscr.com/ch4a8q 

birth certificate wo bhi ap logo k pass already para hoga 

is thra ka - > http://prntscr.com/ch4aor 

Driver licences Hai tw acha hai agar nahi bhi hai tw koi problem nahi ! 

verification form open karne k bad ap ye uplaod karde apne documents scan kar k page per apni pic or cover pic laga dena or birth certificate k saath passport bhi dedena agar apke pass ye dono nahi tw fake try karlo maine real submit kiye hai mujhe reply yehi aya hai k hum apko contact karte hai blue verify badge itni asani se nahi milega itna tw sab mante hai so documents hone k bad bhi wo log chk kar k sab verify akr k ap logo ko badge denge ! 

saath hi ek or baat btata chalun agar apke pass verify ka option nahi ata dono forms mai tw ap Facebook mentions app download karo login kar k jo page hai apke pass uska naam lihko neechy option ajayega your page name -> not verify <- click karte hi form open hojayega apke pass . 

mene passport or birthcertificate send kiya hai uhne Saath hi saahir naqvi jo page blue verify karta tha usne ye bhi kaha tha k wo log meeting fix karte or unka koi ek support wala apko call karta jo number apki id per hota or detials leta saath hi apka sign bhi mangenge ek paper sign kar k scan kar k uhne send krna hota is thra in logo ki verification chalti ye jo dusre group mai kehte k blue verify hogaya kisi ka nahi hua hota because ye log lekar phir unka naam change karte hai ! 

 is liye yehi kehna chachunga kuch kehne se pehle jo method btaya hai ap isse ek dfa try zaroor karlena :) umeed hai jo likha hai ap log usse use bhi karoge thanks .
