Kobe Bryant returned as the LA Lakers squared off with the Toronto Raptors at the Staples Center.

The 35-year-old hadn't played since getting hurt in a home game against Golden State on April the 12th Air Jordan For Sale , so that was last season. But he was back after achillies surgery.

After 240 days out, here he comes, bringing the arena to life.

The return of Kobe also boosted the morale of the Lakers. Look at this attack, Kobe to Steve Blake, and to Wesley Johnson, a super slam dunk. The home crowd enjoying that one.

But the Lakers never led Jordan Retro Shoes For Sale , and Toronto end the first quarter with a shot Kobe himself would have been proud of. Terrence Ross, with a mid-court buzzer-beating three-pointer to move Raptors ahead by ten.

The second quarter saw the home side trim the margin, led by Kobe to Paul Gasol. and back to Kobe with some fake moves bank shot deficit within 4 points.

Kobe looking good. But the Raptors took control of the third quarter, Amir Johnson, who went 14 for 17 and scored a game-high 32 points, put in a two to help the team take a 12-points lead.

And the Raptors spoiled Bryant's big day. His 18th NBA season began with a defeat. Bryant managed 9 points Jordan Retro For Sale , four assists, and eight turnovers.

The Lakers sit at 10th at the Western Conference.

For the other matches on Sunday, Lebron James led Miami with 24 points in their victory over Detroit. Dwight Howard, who?s just celebrated his 28th birthday, pushed Houston past Orlando by 10. Kevin Durant scored 36 points to help Oklahoma City overcome Indiana.

BEIJING Jordan Shoes For Sale , May 23 (Xinhua) -- On a table of 3 square meters are dozens of lenses and odd devices, with wires suspended above and a machine chirping ceaselessly.

It is a prototype quantum computer developed by about 20 Chinese scientists at the Shanghai-based Institute for Quantum Information and Quantum Technology Innovation of the Chinese Academy of Sciences (CAS).

The "baby" quantum computer, unveiled in early May, is the first quantum computing machine based on single photons that could go beyond the early classical -- or conventional -- computer.

The principle of quantum computing is based on one of the strangest phenomena in quantum physics: quantum entanglement. The ancients would see modern electronic technology as akin to witchcraft; most people today would have a similar view of future quantum computing technology.

Scientists say quantum computing exploits the fundamental quantum superposition principle to enable ultra-fast parallel calculation and simulation capabilities. In normal silicon computer chips, data is rendered in one of two states: 0 or 1. In quantum computers, data can exist in both states simultaneously Cheap Air Jordan Retro Shoes For Sale , holding exponentially more information.

The computing power of a quantum computer grows exponentially with the number of quantum bits that can be manipulated. This could effectively solve large-scale computation problems that are beyond the ability of current classical computers, scientists say.

PHOTON WIZARDRY

Lu Chaoyang, a 34-year-old professor at the University of Science and Technology of China (USTC) and one of the developers of the prototype quantum computer, is nicknamed "the photon wizard."

"You can't find two identical leaves in the world, but we can make two identical photons -- even God couldn't tell them apart. With identical photons, we can produce quantum interference and entanglement Cheap Air Jordan Retro For Sale ," says Lu.

The identical photons are produced by a device called a single photon source. The chirping machine is a refrigerator that keeps the single photon source at a temperature of minus 269 degrees centigrade.

"As a result of technological breakthroughs in 2013, our single photon source is the world's best, as 99.5 percent of the photons it produces are identical. It is ten times more efficient than its counterparts abroad," Lu says.

"Using former technology, the photons were like twins playing in mud -- you could distinguish them by the droplets of mud on their bodies. But our technological innovation makes photons like clean indistinguishable twins."

Since the "baby" quantum computer was born, it has done just one thing: play a "game" named Boson sampling Cheap Air Jordan Shoes For Sale , which was designed to enable a quantum computer compete with a classical computer.

"We can manipulate five entangled photons so the machine defeats the early classical computer," says Lu. In fact, the wizard and his colleagues set a new world record of manipulating 10 entangled photons at the end of 2016.

They aim to realize manipulation of 20 entangled photons by the end of this year.

"Although the 'baby' quantum computer can't even beat the mobile phone in your hand, it's a milestone. The first electronic computer in human history, which is so big that it filled several rooms, is worthless today Cheap Air Jordan For Sale , but it is of great scientific significance. We have to develop step by step from science to technology and then to application," Lu says.

"When the car was first invented, it was unreliable and uncomfortable compared with the carriage. But cars eventually surpassed carriages as a result of technological progress."

GREEN SHOOTS

Lu's tutor, Pan Jianwei, a CAS academician and a leading quantum physicist, has spent more than two decades researching the manipulation of microscopic particles.

"At first Cheap Jordan Retro Shoes For Sale , our road was very hard, but now our progress is faster and accelerating. It heralds the coming of a key period in the development of quantum computing. This is like bamboo shoots popping up after the rain," Pan says.

Due to the enormous potential of quantum computing, Europe and the United States are actively collaborating in their research. High-tech companies, such as Google, Microsoft and IBM Cheap Jordan Retro For Sale , also have massive interests in quantum computing research.

The photon-based system is just one of th.
