More insights around the logical quantum gate for photons discovered by Max Planck Institute of Quantum Optics (MPQ). Being able to leverage this gate enables Qubits in transmission and processing can be more controlled and manipulated through this discovery, and places us closer to a stable Quantum Computing environment.


MPQ scientists take an important step towards a logical quantum gate for photons.

Scientists from all over the world are working on concepts for future quantum computers and their experimental realization. Commonly, a typical quantum computer is considered to be based on a network of quantum particles that serve for storing, encoding and processing quantum information. In analogy to the case of a classical computer a quantum logic gate that assigns output signals to input signals in a deterministic way would be an essential building block. A team around Dr. Stephan Dürr from the Quantum Dynamics Division of Prof. Gerhard Rempe at the Max Planck Institute of Quantum Optics has now demonstrated in an experiment how an important gate operation — the exchange of the binary bit values 0 and 1 — can be realized with single photons. A first light pulse containing one photon only is stored as an excitation in an ultracold cloud of about 100,000 rubidium atoms.

All I can say is WOW!!!! US Security Intelligence awards contract to University of Sydney who is also partnering with China. Also, this should send a huge message to the university in the US that Sydney is kicking it.


The US office of the director of national intelligence has awarded a mutlimillion dollar research grant to an international consortium that includes a quantum science laboratory at the University of Sydney.

I am totally jealous right now!


Australia opened a new quantum computing lab at the University of New South Wales (UNSW).

This follows the government’s $26-million investment in the Centre of Excellence for Quantum Computation & Communication Technology (CQC2T) as part of the National Innovation and Science Agenda. The government’s investment is supported by $10 million each from Telstra and the Commonwealth Bank of Australia (CBA).

Today’s digital computers have finite processing power whereas a commercial quantum computer will deliver a significant speed-up in power, including over a supercomputer.

Cambridge’s new nano-scale light-powered piston engine that may one day energize devices to treat diseases directly or deliver drugs.


At the University of Cambridge researchers have developed a nano-scale light-powered piston engine that may one day energize devices to treat diseases directly or deliver drugs in powerful new ways. The device consists of charged gold nanoparticles within a polymer that bends and relaxes in response to heat changes. The polymer absorbs water when cooled, expanding in size, while heating the gold nanoparticles using a laser raises the temperature of the polymer, shedding the absorbed water and relaxing in response. This process happens in a fraction of a second, and as long as a laser is made to flip between being on and off, the engine keeps working.

According to the researchers, the force generated given the weight of the device is quite huge, at least a hundred times greater than existing motors or even muscle cells.

“It’s like an explosion,” said Dr Tao Ding from Cambridge’s Cavendish Laboratory, and the paper’s first author, in a press release. “We have hundreds of gold balls flying apart in a millionth of a second when water molecules inflate the polymers around them.”

A groundbreaking trial to see if it is possible to regenerate the brains of dead people, has won approval from health watchdogs.

A biotech company in the US has been granted ethical permission to recruit 20 patients who have been declared clinically dead from a traumatic brain injury, to test whether parts of their central nervous system can be brought back to life.

Scientists will use a combination of therapies, which include injecting the brain with stem cells and a cocktail of peptides, as well as deploying lasers and nerve stimulation techniques which have been shown to bring patients out of comas.

Predictions from quantum physics have been confirmed by countless experiments, but no one has yet detected the quantum physical effect of entanglement directly with the naked eye. This should now be possible thanks to an experiment proposed by a team around a theoretical physicist at the University of Basel. The experiment might pave the way for new applications in quantum physics.

Quantum physics is more than 100 years old, but even today is still sometimes met with wonderment. This applies, for example, to entanglement, a quantum physical phenomenon that can be observed between atoms or photons (light particles): when two of these particles are entangled, the physical state of the two particles can no longer be described independently, only the total system that both particles form together.

Despite this peculiarity, entangled photons are part of the real world, as has been proven in many experiments. And yet no one has observed entangled photons directly. This is because only single or a handful of entangled photons can be produced with the available technology, and this number is too low for the to perceive these photons as light.

In this new short written and directed by the Brothers Lynch, a pioneering mind transfer procedure offers a quadriplegic soldier the opportunity to start a new life. Naturally, things don’t go quite as planned.

This teaser short, titled Trial, is a miniature version of an intended full-length sci-fi action thriller called Residual. Backed by Creative England, the new short is meant to help with the financing of the proposed feature.

Trial was produced by Ed Barratt of Hook Pictures, and it stars Tom Cullen, Ana Ularu and Joseph Mawle. Go here to learn more.
