Spherical shell laser sail would simplify interstellar laser sails

Posted by in category: space travel

The stability of a light sail riding on a laser beam is analyzed both analytically and numerically. Conical sails on Gaussian beams, which have been studied in the past, are shown to be unstable in general. A new architecture for a passively stable sail and beam configuration is proposed. The novel spherical shell sail design is capable of “beam riding” without the need for active feedback control. Full three-dimensional ray-tracing simulations are performed to verify our analytical results.

22 Minutes: The Independents

Posted by in categories: geopolitics, transhumanism

Canada’s favorite comedy show 22 Minutes of CBC (similar to The Daily Show) is out tonight with a new broadcast. My campaign and transhumanism is in it for a few minutes. Here’s a 4 minute YouTube clip from the TV broadcast that’s quite funny. Shows sometimes get a million views across Canada:


Is America ready for the first redneck, gun toting, mullet sporting, tiger tackling, gay polygamist president? Shaun Majumder investigates.

Humans need new skills for post-AI world, say MPs

Posted by in categories: government, law, robotics/AI

Robotics and AI have “huge potential” to reshape the way people work and live, but the government needs to do more to address the issues raised by such technology, says a report.

MPs on the Science and Technology Committee have called for careful scrutiny of the probable ethical, legal and societal impact.

They want the government to establish a commission to look at the issues.

Massive Disruption Is Coming With Quantum Computing

Posted by in categories: computing, quantum physics, robotics/AI

As I and others have warned industry about for a ling while now. Wait until you see the AI experience on QC and how we enable synthetic biocomputing on this connected infrastructure.


Next year, we may see the launch of the first true quantum computers.

Physicists Have Quantum Computing A Step Closer To Reality

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

The world of quantum computing is a minefield. The more scientists think they know about it, the more they realize there’s so much more to learn. But, with thanks to physicists in a laboratory in Canberra, we are that one step closer to seeing a real life working quantum computer as they managed to freeze light in a cloud of atoms. This was achieved by using a vaporized cloud of ultracold rubidium atoms to create a light trap into which infrared lasers were shone. The light was then constantly emitted and re-captured by the newly formed light trap.

Electron spins talk to each other via a ‘quantum mediator’

Posted by in categories: computing, nanotechnology, quantum physics

The unparalleled possibilities of quantum computers are currently still limited because information exchange between the bits in such computers is difficult, especially over larger distances. FOM workgroup leader Lieven Vandersypen and his colleagues within the QuTech research centre and the Kavli Institute for Nanosciences (Delft University of Technology) have succeeded for the first time in enabling two non-neighbouring quantum bits in the form of electron spins in semiconductors to communicate with each other. They publish their research on 10 October in Nature Nanotechnology.

Information exchange is something that we scarcely think about these days. People constantly communicate via e-mails, mobile messaging applications and phone calls. Technically, it is the bits in those various devices that talk to each other. “For a normal computer, this poses absolutely no problem,” says professor Lieven Vandersypen. “However, for the quantum computer – which is potentially much faster than the current computers – that information exchange between quantum bits is very complex, especially over long distances.”

The two electrons are each trapped in a semiconductor nanostructure (quantum dot). The two spins interact, and this interaction is mediated by a third, empty quantum dot in the middle. In the future, coupling over larger distances can be achieved using other objects in between to mediate the interaction. This will allow researchers to create two-dimensional networks of coupled spins, that act as quantum bits in a future quantum computer. Copyright: Tremani/TU Delft.

Atomic-scale MRI holds promise for new drug discovery

Posted by in categories: biotech/medical, computing, quantum physics

Researchers at the University of Melbourne have developed a way to radically miniaturise a Magnetic Resonance Imaging (MRI) machine using atomic-scale quantum computer technology.

Capable of imaging the structure of a single bio-molecule, the new system would overcome significant technological challenges and provide an important new tool for biotechnology and drug discovery.

The work was published today in Nature Communications, and was led by Prof Lloyd Hollenberg at the University of Melbourne, working closely with researchers at the ARC Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) to design the quantum molecular microscope.

Quantum Computing Could Cripple Encryption; Bitcoin’s Role

Posted by in categories: bitcoin, business, cybercrime/malcode, encryption, government, quantum physics

Earlier this week, Canada’s electronic spy agency the Communications Security Establishment warned government agencies and businesses against quantum mechanics, which could cripple the majority of encryption methods implemented by leading corporations and agencies globally.

Governments and private companies employ a variety of cryptographic security systems and protocols to protect and store important data. Amongst these encryption methods, the most popular system is public key cryptography (PKC), which can be integrated onto a wide range of software, platforms, and applications to encrypt data.

The Communications Security Establishment and its chief Greta Bossenmaier believes that quantum computing is technically capable of targeting PKC-based encryption methods, making data vulnerable to security breaches and hacking attempts from foreign state spies and anonymous hacking groups.
