Google Quantum Computer : 100X Faster than a PC

Announcing the results of its experiment, Google says Quantum Computer is More than 100 Million times faster than a regular PC.

Two years ago, Google and NASA (National Aeronautics and Space Administration) bought a D-Wave 2X quantum computer, which they have been experimenting at the U.S. space agency's Ames Research Center in Mountain View, California for the past two years.

The goal is to create a better way to solve highly complex problems in seconds rather than years.

Now, a Google's Quantum AI team appears to have announced the results of its latest test on D-Wave 2X quantum computer, demonstrating that quantum annealing can outperform simulated annealing by over 108 times – that is 100,000,000 times faster.

What is Quantum Computers?

Quantum computers can theoretically be so much faster because they take advantage of quantum mechanics. While traditional computers use the "bits" to represent information as a 0 or a 1, quantum computers use "qubits" to represent information as a 0, 1, or both at the same time.

In turn, this allows Quantum computers to achieve a correct answer much faster and efficiently through parallel processing.

Google's D-Wave 2X Quantum Computer:

Now, the Google Quantum Artificial Intelligence Lab has announced that its D-Wave machine is considerably much faster than simulated annealing – quantum computation simulation on a classical computer chip.

"We found that for problem instances involving nearly 1000 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," said Hartmut Neven, Google's director of engineering.

Google: Our Quantum Machine is 100 Million Times Faster

Google has also published a paper [PDF] on the findings, claiming that the team was able to perform a calculation with the quantum computing technology that was significantly faster than a conventional computer with a single core processor.

The researchers emphasized that their research on quantum computing is still in the early stages and has yet to be commercialized which could take decades.

"While these results are intriguing and very encouraging, there is more work ahead to turn quantum enhanced optimization into a practical technology," Neven wrote.

However, the team of Google and NASA researchers announced on Tuesday that the tests on D-Wave machines using Quantum Monte Carlo algorithm simulates running an optimization problem on ordinary silicon, and again the results were more than 100 Million times faster than a conventional computer

Li-Fi is 100 Times Faster than Wi-Fi Technology - Practically Proved

Yes, it's time to shift from Wi-Fi to Li-Fi — an alternative technology that is 100 times faster than the average speeds of Wi-Fi.

Scientists have just field-tested the new wireless technology called Li-Fi for the first time and achieved marvelous wireless speeds that are 100 times faster than current WiFi speeds.

What is Li-Fi Technology?

Li-Fi is a new wireless technology that transmits high-speed data using light (i.e. Visible Light Communication or VLC) rather than radio bands.

In short, Li-Fi is a Super-Fast alternative to Wi-Fi.

Earlier this year, scientists achieved mind-blowing speeds of 224 gigabits per second (Gbps) in the lab using Li-Fi. It's believed that this technology has the potential to change everything about the way we use the Internet today.

And Yes, it will.

Test Results: Li-Fi is 100 times Faster than Wi-Fi

An Estonian startup company called Velmenni took the technology out of the laboratories and into the real-world offices, and industrial environments in Tallinn for the first time and, believe me, it's really, really fast.

The company was able to transmit data at 1GB per second, which is almost 100 times faster than the Wi-Fi speeds.

"We are doing a few pilot projects in different industries where we can utilize the VLC technology,"Velmenni's CEO Deepak Solanki told IBTimes UK.
"Currently we have designed a smart lighting solution for an industrial environment where the data communication is done through the light. We're also doing a pilot project with a private client where we're setting up a Li-Fi network to access the Internet in [our] office space."

Unlike Wi-Fi network signals, Li-Fi is based on light and can't penetrate through walls, which makes it more secure from external sniffing. Meanwhile, it also means there is less interference from other devices.

Who Invented Li-Fi?

The Li-Fi technology was originated in 2011 by German physicist Harald Haas, who outlined the idea of using light bulbs as wireless routers during a TED Talk. He demonstrated that with a flickering light from an LED, one could transmit more data than a cellular tower.
