This fun, easy and in-depth video explains the complexities of quantum computing and how it could dramatically change our lives once it’s here.
Colors from darkness: Researchers develop alternative approach to quantum computing
Another approach to QC; the title of the article is misleading because you still are using quantum properties in the approach.
Researchers at Aalto University have demonstrated the suitability of microwave signals in the coding of information for quantum computing. Previous development of the field has been focusing on optical systems. Researchers used a microwave resonator based on extremely sensitive measurement devices known as superconductive quantum interference devices (SQUIDs). In their studies, the resonator was cooled down and kept near absolute zero, where any thermal motion freezes. This state corresponds to perfect darkness where no photon — a real particle of electromagnetic radiation such as visible light or microwaves — is present.
However, in this state (called quantum vacuum) there exist fluctuations that bring photons in and out of existence for a very short time. The researchers have now managed to convert these fluctuations into real photons of microwave radiation with different frequencies, showing that, in a sense, darkness is more than just absence of light.
They also found out that these photons are correlated with each other, as if a magic connection exists between them.
NREL Discovery Creates Future Opportunity in Quantum Computing

Government sees potential ‘quantum ecosystem’ in Australia
I will have to admit Australia is pretty advance in its research and development efforts in QC. With Michelle Simmons and team they certainly give folks a run for their money in the QC race.

Letter: U.S. lags far behind China in quantum computing technology
The Wall Street Journal on Aug. 16 reported that China sent the world’s first quantum communications satellite into orbit. The newspaper also stated that China spent $101 billion in 2015 on quantum research and technology development. The satellite has the ability to greatly expand China’s ability to expand their unhackable communications.
Now we in the U.S. read almost daily about some U.S. computer system that has been hacked. Our current technology cannot be considered secure. So what is our government investing in?
According to the GAO, the U.S. spent over $10 billion on global climate change science and technology in 2014. Gave $400 million to Iran for who knows what, and spent about $200 million on quantum technology.
Physicist proposes new equation that could transform physics
In 1935, physicists published two papers introducing key concepts on the theoretical understanding of the universe: wormholes and quantum entanglement.
But, what if these two separately described phenomena were actually the same thing?
A Stanford physicist has proposed this radical idea in the form of a new equation, ER=EPR – and he says it could build a space-time bridge between the long-competing theories of general relativity and quantum mechanics.
Black Holes are likely sending quantum messages in the universe
Spinning black holes are capable of complex quantum information processes encoded in the X-ray photons emitted by the accretion disk.
The black holes sparked the public imagination for almost 100 years now. Their debated presence in the universe has been proven without a doubt by detecting the X-ray radiation coming from the center of the galaxies, a feature of massive black holes. Black holes emit X-ray radiation, light with high energy, due to the extreme gravity in their vicinity. The vast majority if not all of the known black holes were unveiled by detecting the X-ray radiation emitted by the stellar material accreting around black holes.
X-ray photons emitted near rotating black holes not only exposed the existence of these phantom-like astrophysical bodies, but also seem to carry hidden quantum messages.
