String theory arrived in the public field in 1988 when a BBC radio series Desperately Seeking Superstrings was aired. Thanks to good marketing and its naturally curious name and characteristics, it is now part of popular discourse, mentioned in TV’s Big Bang Theory, Woody Allen stories, and countless science documentaries.
Might nature’s bottomless pits actually be ultra-efficient quantum computers? That could explain why data never dies.
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.
Making a more ultrafast optical switch and can be used to control or address individual spin states, which is needed for spin-based quantum computing.

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.
MIS Asia offers Information Technology strategy insight for senior IT management — resources to understand and leverage information technology from a business leadership perspective.
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.

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?
