Data Compression Used to Detect Quantum Entanglement
Posted by Karen Hurst in categories: information science, particle physics, quantum physics
Interesting — data compression algorithm can be applied to detect Quantum Entanglement.
The next time you archive some files and compress them, you might think about the process a little differently. Researchers at the National University of Singapore have discovered a common compression algorithm can be used to detect quantum entanglement. What makes this discovery so interesting is that it does not rely on heavily on an assumption that the measured particles are independent and identically distributed.

Google believes artificial intelligence will be bigger than virtual reality
Posted by Karen Hurst in categories: cybercrime/malcode, quantum physics, robotics/AI, virtual reality
I too believe AI could be bigger in the future once the under pinning technology and infrastructure moves to Quantum Technology so that hacking is under control and performance is where it needs to be.
When Mark Zuckerberg thinks about the future, he sees a world that’s dominated by mobile devices and virtual reality, but when Google CEO Sundar Pichai thinks about the future, all he sees is artificial intelligence. He suggested as much during Alphabet’s quarterly earnings call on Thursday, saying that mobile devices and virtual reality will dominate the immediate future, but that they’ll eventually be surpassed in importance by artificial intelligence. However, he didn’t go into detail about what this future will look like.
Artificial intelligence is nothing new at Google, but today we learned just how big a role top boss Sundar Pichai sees AI playing in our future. Answering an analyst query on Google-parent company Alphabet’s Q1 2016 earnings call about how the company is leading innovation, rather than simply adapting to changes in technology, Pichai talked about his role in projecting where Alphabet is going in the next 10 years. He gave a shout out to VR as the hot new platform, and then wrapped up his comments by saying: “In the long run, I think we will evolve in computing from a mobile-first world to an AI-first world.” Earlier in the call he cited Google’s DeepMind AlphaGo super computer defeating a human champion as an extraordinary achievement. He also said the company is investing in AI and machine learning, areas that are taking off and beginning to bear real-world benefits.

Team builds first quantum cascade laser on silicon
Posted by Karen Hurst in categories: computing, quantum physics
Very nice; Silicon based Quantum Laser has been achieved. Imagine what this does for ISPs and other communications. smile
A team of researchers from across the country, led by Alexander Spott, University of California, Santa Barbara, USA, have built the first quantum cascade laser on silicon. The advance may have applications that span from chemical bond spectroscopy and gas sensing, to astronomy and free-space communications.
Integrating lasers directly on silicon chips is challenging, but it is much more efficient and compact than coupling external laser light to the chips. The indirect bandgap of silicon makes it difficult to build a laser out of silicon, but diode lasers can be built with III-V materials such as InP or GaAs. By directly bonding an III-V layer on top of the silicon wafer and then using the III-V layers to generate gain for the laser, this same group has integrated a multiple quantum well laser on silicon that operates at 2 µm. Limitations in diode lasers prevent going to longer wavelengths where there are many more applications, so the group turned their attention to using quantum cascade lasers instead.

Zip software can detect the quantum-classical boundary (w/video)
Posted by Karen Hurst in categories: computing, quantum physics
Quantum physics has a reputation for being mysterious and mathematically challenging. That makes it all the more surprising that a new technique to detect quantum behaviour relies on a familiar tool: a “zip” program you might have installed on your computer.
“We found a new way to see a difference between the quantum universe and a classical one, using nothing more complex than a compression program,” says Dagomir Kaszlikowski, a Principal Investigator at the Centre for Quantum Technologies (CQT).
Dag worked with other researchers from CQT and collaborators at the Jagiellonian University and Adam Mickiewicz University in Poland to show that compression software, applied to experimental data, can reveal when a system crosses the boundary of our classical picture of the Universe into the quantum realm. The work is published in the March issue of New Journal of Physics (“Probing the quantum–classical boundary with compression software”).

The researchers call their material a hybrid because they dope the electrical conductivity of layered tin disulfide semiconductor with the light harvesting of different spectrums of light from various sized quantum dots.

A ‘big science’ approach for Australian cybersecurity research?
Posted by Karen Hurst in categories: cybercrime/malcode, education, quantum physics, science
Australia should go “Big Science” on addressing Cyber Security. I believe Australia is already making strides in Cyber Security with their own advancements in Quantum.
Australia’s Cyber Security Strategy, to be released this Thursday, will include an emphasis on research and development, as well as education. How might that unfold?

General Motors to double size of Israel R&D center

Regulation is not the immediate problem with autonomous cars. Example, is Google car has been deemed approved by existing regs. However, the issue is the broader public’s trust due to the various reports of hacking of connected cars such as the Nissan Leaf, etc. Until we put in place a more resilient net infrastructure such as Quantum; slow down will happen. I suggest GM to read the news more because everything that I stated has been well communicated in the news and research for the past 4 months.
GM Ventures president Lauckner believes regulation will not halt the advance of the autonomous car.

Information is physical, even in quantum systems, study suggests
Posted by Karen Hurst in category: quantum physics
I believe that the assumption around data/ information on a Quantum platform would always be considered physical not virtual.
A thermodynamic principle says that deleting information generates heat, and now, scientists say that goes for quantum systems, too.
