Google Quantum
Quantum computing has long dangled the possibility of superfast, super-efficient processing, and now search giant Google has jumped on board that future. New Scientist reports that Google has spent the past three years developing a quantum algorithm that can automatically recognize and sort objects from still images or video. The promise of quantum computing rests 
with the bizarre physics that occurs at the subatomic level. Different research teams have worked on creating quantum processors that store information as qubits (quantum bits), which can represent both the 1 and 0 of binary computer language at the same time. That dual possibility state allows for much more efficient processing and information storage. To take an example cited by Google, a classical computer might need 500,000 peeks on average to find a ball hidden somewhere within a million drawers. But a quantum computer could find the ball by just looking into 1,000 drawers — a nice little stunt known as Grover's algorithm. Google has been using a quantum computing device created by D-Wave, a Canadian firm. But a lack of information about how D-Wave's chip works has led to outside skepticism regarding whether it does indeed count as a quantum computer. "Unfortunately, it is not easy to demonstrate that a multi-qubit system such as the D-Wave chip indeed exhibits the desired quantum behavior and experimental physicists from various institutions are still in the process of characterizing the chip," wrote Hartmut Neven, head of Google's image recognition team, on the Google research blog. Whatever D-Wave built has apparently worked for Google. Neven described a new algorithm based on the work of MIT that can sort images of cars from among 20,000 photos faster than anything running in a Google data center today — although the team first trained the algorithm by hand-labeling cars in a test photo batch. Google's image recognition team has previously made its algorithms work for better online image searches and automatic photo organization. Perhaps we shouldn't be too surprised that the Google folk have also delved into quantum computing, or at least something much faster than existing classical computing.

How to Setup A Linux Dialup Connection (Wireless Modem HUAWEI ETS2551)
Setup A Linux Dialup Connection(Wireless Modem HUAWEI ETS2551)
Use it at Your Own Risk
This guide is useful for setting Wireless Modem HUAWEI ETS2551 dialup connection provided by PTCL in Pakistan or with any other service provider in any other Country (Just u can try). Can be set on HUAWEI ETS2051/2251 . But not tested on them. OK
Hardware Requirements
* USB/Serial Cable.
* ETS2551 Huawei modem.
System Requirements
* Linux with kernel above 2.6.** (Check it by command in console uname -a).
(Personally Tested on Suse 10.1 and FC5 with ETS2551)
Let's Start
It is well assumed that Linux is up on your system and your USB/Serial cable is plugged in.
Now in console type command dmesg -c search for the following lines
ti_usb_3410_5052 1-1:2.0: TI USB 3410 1 port adapter converter detected
usb 1-1: TI USB 3410 1 port adapter converter now attached to /dev/ttyUSB0
If u even see ttyUSB0 in the kernel message then also your modem is detected and you are ready to start,now just configure your wvdial.conf in /etc and start your dialup.
If not then possibly u will be seeing the following error messages in bundle but i will paste only two lines here.
ti_usb_3410_5052 1-1:1.0: TI USB 3410 1 port adapter converter detected
ti_usb_3410_5052: probe of 1-1:1.0 failed with error -5
Hello My Friends : ===> Note that the problem is only the USB/Serial Cable not the HUAEWI modem OK.
Now we have to make one rule file in /etc/udev/rules.d/026_ti_usb_3410.rules .In console login as a root
su
password *****
cd /etc/udev/rules.d/
vi 026_ti_usb_3410.rules (Now Paste the following lines in it)
#TI USB 3410
SUBSYSTEM=="usb_device" ACTION=="add" SYSFS{idVendor}=="0451",SYSFS{idProduct}=="3410" \
SYSFS{bNumConfigurations}=="2" \
SYSFS{bConfigurationValue}=="1" \
RUN+="/bin/sh -c 'echo 2 > /sys%p/device/bConfigurationValue'"
SAVE AND EXIT
Now once again plug out ur USB/Serial cable and then plugin.
Again type dmesg -c in console
Check the kernel message and find the following line
ti_usb_3410_5052 1-1:2.0: TI USB 3410 1 port adapter converter detected
usb 1-1: TI USB 3410 1 port adapter converter now attached to /dev/ttyUSB0
CONGRATULATIONS it is finally done.
Now edit your /etc/wvdial.conf (Mine as a Sample below working fine)
My /etc/wvdial.conf
[Dialer ptcl]
Modem = /dev/ttyUSB0
Baud = 230400
Phone = #777
Init1 = ATZ
Stupid Mode = 1
Dial Command = ATDT
Username = vwireless@ptcl.com
Password = ptcl
PPPD Options = crtcts multilink usepeerdns lock defaultroute
Important Note: Stupid Mode should be set to 1 otherwise the hash sign # with Dialing phone number will not be treated by wvdial. OK.
LAST PROBLEM.
When u will connect to ptcl with wvdial ptcl command as a root , it will not browse any page and will disconnect.
You have to set the nameserver in the /etc/resolv.conf .You can get the nameserver IPs from the terminal window when wvdial is trying to connect to your ISP.
Put those two nameserver in /etc/reslov.conf.
Now again as a root in console wvdial ptcl. .
