About ten years ago scientist Dave Bacon, now at Google, presented that a time-travelling quantum computer could rapidly solve a bunch of problems, known as NP-complete, which mathematicians have lumped together as being hard. The problem was, Bacon’s quantum computer was travelling around ‘closed timelike curves’. These are paths through the fabric of spacetime that loop back on themselves. General relativity lets such paths to exist through contortions in spacetime identified as wormholes.

Why send a message back in time, but lock it so that no one can ever read the contents? As it may be the key to resolving presently intractable problems. That’s the claim of an international collaboration.

Given the fact that Los Alamos Labs have been and continue to advance cyber security work on the Quantum Internet as well as work in partnerships with other labs and universities; so, why isn’t Mason not collaborating with Los Alamos on developing an improved hacker proof net? Doesn’t look like the most effective and cost efficient approach.

Imagine burglars have targeted your home, but before they break in, you’ve already moved and are safe from harm.

Now apply that premise to protecting a computer network from attack. Hackers try to bring down a network, but critical tasks are a step ahead of them, thanks to complex algorithms. The dreaded “network down” or denial of service message never flashes on your screen.

Theoretical chemists at Princeton University have pioneered a strategy for modeling quantum friction, or how a particle’s environment drags on it, a vexing problem in quantum mechanics since the birth of the field. The study was published in the Journal of Physical Chemistry Letters (“Wigner–Lindblad Equations for Quantum Friction”). “It was truly a most challenging research project in terms of technical details and the need to draw upon new ideas,” said Denys Bondar, a research scholar in the Rabitz lab and corresponding author on the work.

Researchers construct a quantum counterpart of classical friction, a velocity-dependent force acting against the direction of motion. In particular, a translationary invariant Lindblad equation is derived satisfying the appropriate dynamical relations for the coordinate and momentum (i.e., the Ehrenfest equations). Numerical simulations establish that the model approximately equilibrates. (© ACS)

A new form of light which makes fiber optics more secure. Los Alamos has been key player in this space due to their work on the Quantum Internet.

In a breakthrough that has the potential to alter our understanding of the fundamental nature of light, scientists from the Trinity College Dublin School of Physics and the CRANN Institute in Ireland have discovered a never before seen new form of luminescence.

Lead author Paul Eastham attests to how exciting this finding is, saying in a statement that this very fundamental property of light that has always been thought to be constant can, in fact, change.

A new form of light has been discovered by physicists from Trinity College Dublin’s School of Physics and the CRANN Institute, Trinity College, which will impact our understanding of the fundamental nature of light.

One of the measurable characteristics of a beam of light is known as angular momentum, The Spectrum reports. Until now, it was thought that in all forms of light the angular momentum would be a multiple of Planck’s constant (the physical constant that sets the scale of quantum effects).

Now, recent PhD graduate Kyle Ballantine and Professor Paul Eastham, both from Trinity College Dublin’s School of Physics, along with Professor John Donegan from CRANN, have demonstrated a new form of light where the angular momentum of each photon (a particle of visible light) takes only half of this value. This difference, though small, is profound. These results were recently published in the online journal Science Advances.

Imec will implement qubits and supporting nanoelectronic functionality for quantum computing, leveraging its advanced silicon (Si) platform that was established within the framework of its industrial affiliation program with additional support from the EU through e.g. ECSEL projects SENATE and TAKE-5.

EU betting big on Quantum Technology.

The European Union (EU) aims to embark on an ambitious common strategy on quantum technologies, European Commissioner for digital economy and society Gunther Oettinger said here Tuesday.

At a conference which brought together some of the world’s leading experts in the field of quantum technology, European scientists and entrepreneurs launched a “Quantum Manifesto” laying out future priorities and activities to create a new “knowledge-based industrial ecosystem” in Europe.

“We aim to launch an ambitious large-scale flagship initiative to unlock the full potential of quantum technologies, accelerate their development, and bring commercial products to public and private users,” Oettinger told the conference.

DUBLIN, Ireland, May 17 (UPI) — Researchers in Ireland have discovered a new form of light. Their discovery is expected to reshape scientists’ understanding of light’s basic nature.

Angular momentum describes the rotation of a light beam around its axis. Until now, researchers believed the angular momentum was always a multiple of Planck’s constant — a constant ratio that describes the relationship between photon energy and frequency, and also sets the scale for quantum mechanics.

The newly discovered form of light, however, features photons with an angular momentum of just half the value of Planck’s constant. The difference sounds small, but researchers say the significance of the discovery is great.

Physicists have just discovered a new form of light that doesn’t follow our existing rules of angular momentum, and it could shake up our understanding of the electromagnetic radiation and lead to faster, more secure optical communication.

Because of how well-studied and, well, everywhere, light is, you might assume that we’ve pretty much learnt all there is to know about it. But just last year, researchers identified a fundamental new property of light, and now a team of Irish scientists has shown that light can take on unexpected new forms.
