New device steps us towards quantum computing

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

If biochemists had access to a quantum computer, they could perfectly simulate the properties of new molecules to develop drugs in ways that would take today’s fastest computers decades. A new device takes us closer to providing such a computer. The device successfully traps, detects, and manipulates an ensemble of electrons above the surface of superfluid helium. The system integrates a nanofluidic channel with a superconducting circuit.

Because they are so small, electrons normally interact weakly with electrical signals. The new device, however, gives the electron more time to interact, and it is this setup that makes it possible to build a qubit, the quantum computing equivalent of a bit. Quantum computers could provide the necessary computing power to model extremely large and complex situations in physics, biology, weather systems and many others.

While isolated electrons in a vacuum can store quantum information nearly perfectly, in real materials, the movements of surrounding atoms disturbs them, eventually leading to the loss of information. This work is a step towards realizing isolated, trapped single electrons by taking advantage of the unique relationship existing between electrons and superfluid helium. Electrons will levitate just above the surface of helium, about 10 nanometers away, insensitive to the atomic fluctuations below. While this effect has been known, holding them in a superconducting device structure has not been demonstrated before this work. At the heart of this new technology is a resonator based on circuit quantum electrodynamics (cQED) architecture, which provides a path to trap electrons above helium and detect the spins of the electrons. Because they are so small, electrons normally interact only very weakly with electrical signals.

Physicists say time travel could be a reality

Posted by in categories: information science, quantum physics, time travel

Interesting…


However, new research carried out at the University of Waterloo and University of Lethbridge, in Canada, argues there is a much longer measureable minimum unit of time.

If true, the existence of such a minimum time changes the basic equations of quantum mechanics.

Physicists Just Observed a Brand-New State of Matter Where We Thought It Was Impossible

Posted by in categories: computing, quantum physics

Physicists assert that they have observed quantum spin liquid state again; however, this time, they have done so in a material where it was thought to be impossible. If verified, it could transform how we understand quantum computing.

Back in April, the physics world freaked out when scientists confirmed that they’d made the first direct observation of a brand-new state of matter – known as quantum spin liquid – for the first time.

China’s new quantum satellite paves the way for unhackable satellite internet

Posted by in categories: cybercrime/malcode, encryption, internet, quantum physics, satellites

All that I can say is “WOW!”


CHINA is on the brink of launching a groundbreaking new satellite capable of conducting quantum experiments in space, leading some to predict it will usher in the beginning of a new space race.

The world will be watching very closely after the Chinese-led satellite launches in August. If it proves successful in carrying out the quantum experiments, China is expected to follow it with many more in a bid to create a super secure network that uses an encryption technique based on the principles of quantum communication.

Apple Advances Work on Quantum Dot Displays for Future Macs, iOS Devices & Possible TV

Posted by in categories: energy, mobile phones, quantum physics

Apple and Q-Dots.


While we know that Apple’s next display shift will be to OLED for their 2017 Anniversary edition iPhone, Apple is always looking to the next wave technology just on the horizon. So what’s beyond OLED? At the moment, many think the next trend points to Quantum Dot LED or QDLED. While the structure of a QLED is very similar to OLED technology, the difference is that the light emitting centers are cadmium selenide nanocrystals, or quantum dots. Theoretically, the advantages to this type of display is that it could reportedly deliver brighter ‘pure color’ and consumes less power, in fact close to 50% less power. The technology is also ideal for consumer devices that demand a flexible display. When Apple first introduced their vision of an Apple Watch in 2013, they presented it with a ‘continuous’ display that completely wraps around a users wrist as noted in the patent figure below. A QDLED type of display would allow such a form factor to come to market.

Scientia Professor Michelle Yvonne Simmons

Posted by in categories: computing, quantum physics

Professor Michelle Simmons of the Univ. of Sydney is an early pioneer of QC and will go down in history as the 1st Mother of Quantum Computing and a person that all (women and men) can look up to and be a true role model for many in tech and science. I hope to continue to make young girls and women everywhere to learn about her and hopefully they (like me) will consider her a role model to follow.

A new Type of Quantum Bit

Posted by in categories: materials, quantum physics

In approaches using conventional semiconductor materials, scientists typically created qubits in the form of individual electrons. However, this caused dephesing, and the information carriers were difficult to program and read. Now, researchers from the University of Basel, Ruhr University Bochum, and the Universite de Lyon have overcome this problem by using holes — instead of electrons — to create qubits.

White House’s “ADVANCING QUANTUM INFORMATION SCIENCE: NATIONAL CHALLENGES AND OPPORTUNITIES”

Posted by in categories: government, internet, quantum physics, science

Nice paper on QC from the Obama Administration. While reading this paper; I also kept in mind why the US, Europe, Canada, etc. all must accelerate our efforts on QC which is government backed hackers in China, etc. especially since China will have a Quantum Internet and have also accelerated their efforts on QC with their partnership with Australia’s QC efforts which many discoveries on QC has happened.
