Viewpoint: Mapping Out the State of a Quantum System

Posted by in categories: mathematics, quantum physics

Researchers have developed a new technique to measure the density matrix—a more general way of characterizing the state of a quantum system than that provided by the wave function.

The wave function is the physicist’s usual choice to characterize the state of a quantum system. But a different mathematical object, called a density matrix, is required for systems that are in mixed states, which are a mixture of other, pure quantum states. An example of a pure state is a beam of horizontally or vertically polarized photons, whereas a mixed state would be an uncorrelated statistical mixture of both polarizations. A mixed state would also apply to a system quantum mechanically entangled with its environment. The density matrix provides a complete description of a mixed state, but it also applies to pure states. Usually, experimental measurements of density matrices are indirect reconstructions using data acquired from a series of different kinds of measurements.

Will Quantum Computers Transform The Next Century?

Posted by in categories: computing, particle physics, quantum physics

Hmmmm; I suggest that “Kate” needs to follow up with the research teams at the University of Sydney, MIT, ORNL, and University of China who have already proven and shared insights and techniques to stabilize QC, make it scalable (as we are already seeing Google leverage), and trace particles throughout entanglement. I really do not like ready articles that misleads the public because the author was lazy in not doing their own research and homework on their topics.


Today I’d like to speak about quantum computers and to share my ideas of their purpose in the nearest future. As you know, applying the laws of quantum mechanics it’s actually possible to create a new type of computing machine, enabling to solve some of the issues, being currently unable to resolve even upon the use of the most powerful machines. As a result, the speed of major complex computations will significantly increase, for instance, the messages sent via quantum coupling lines will be impossible to capture or to copy. Sounds quite fantastic, isn’t it? Furthermore, today we already have working prototypes of future quantum computers. So, let’s consider this topic more precisely.

Nothing can escape from this new Chinese quantum radar, not even stealth jet

Posted by in categories: quantum physics, transportation

More things keep being revealed; and this only what the public knows to boot.


With an aim of detecting ever object within the range, China has developed a new radar technology that is capable of detecting stealth jets, claims a Chinese firm. According to the reports, the branch of defence and electronics firm CETC — Intelligent Perception Technology created the quantum radar which can detect any target withing a 60 miles range and it was successfully tested last month.

Chinese news agency Xinhua reported that the radar uses has superior detection capabilities as it uses quantum entanglement photons which is better than traditional detection systems. The new technology will enable the radar to even detect modern aircraft that can escape the radar, uses stealth technology or baffle the enemy radar system.

INGLES: China says it has stealth-defeating quantum radar

Posted by in categories: electronics, quantum physics

Hmmmm.


Read more China receives first data from unique ‘hack-proof’ quantum satellite The first Chinese quantum radar was developed by the Intelligent Perception Technology Laboratory of the 14th Institute in CETC, according to Xinhua news agency. CETC stands for Electronics Technology Group Corporation, a defense and electronics firm.

The radar was tested in mid-August, Xinhua said in a Thursday report.

New Quantum Chip Could Bring Highest Level of Encryption to Any Mobile Device

Posted by in categories: computing, encryption, mobile phones, quantum physics, security

Nice.


“We’ve managed to put quantum-based technology that has been used in high profile science experiments into a package that might allow it to be used commercially.”

Random number generators are crucial to the encryption that protects our privacy and security when engaging in digital transactions such as buying products online or withdrawing cash from an ATM. For the first time, engineers have developed a fast random number generator based on a quantum mechanical process that could deliver the world’s most secure encryption keys in a package tiny enough to use in a mobile device.

Your Next Phone Could Have Quantum Security

Posted by in categories: computing, mobile phones, quantum physics, security

As I mentioned 4 months ago when an article came out stating that this type of concept of a scalable quantum chip was at least 15 years away was bunk; this is again one more example where contributors really need to do their homework and make sure they are speaking to the real folks on the frontlines of QC.


Quantum-based random number generators are now small enough that they could fit in mobile devices.

Google’s Quantum Computer May be Superior to Conventional Computers by 2018

Posted by in categories: computing, quantum physics

Insiders indicate that Google may be nearing its goal of “quantum supremacy,” creating a computer that can outperform classical computers (at least in some tasks) by the end of next year.

If there’s one thing that’s painfully clear, its that classical computing tech is nearing its limit. Many have predicted the end of Moore’s law, and they are looking at the next step in the computing world: quantum computers.

And new reports assert that we may be on the verge of a breakthrough.
