Quantum computing, here we come: A qubit data bus may soon be possible

Posted by in categories: computing, quantum physics

Transporting information from one place to another is a key part of any computing platform, and now researchers have figured out a way to make it possible in the quantum world.

To prove their point, they demonstrated what’s known as perfect state transfer on a photonic qubit that’s entangled with another qubit at a different location.

In traditional computing, numbers are represented by either 0s or 1s. Quantum computing relies on atomic-scale quantum bits, or “qubits,” that can be simultaneously 0 and 1—a state known as superposition. Quantum bits can also become “entangled” so that they are dependent on one another even across distances.

Qubiz aims to make quantum technology practical

Posted by in categories: business, engineering, quantum physics

Excellent news!!!!!


The Quantum Innovation Center or Qubiz has been launched in Copenhagen with the goal of translating quantum physics into practical quantum technology. The Danish project involves the Niels Bohr Institute at the University of Copenhagen, the Technical University of Denmark DTU, and Aarhus University, along with 18 industrial partners. Qubiz will be building on the very strong Danish research platform within quantum technology, a platform that has its origin in Niels Bohr’s pioneering work 100 years ago.

The CEO for the new Center is Søren Isaksen, who previously served as the CTO of the NKT Group and is a member and chairmen of various research councils. In addition to leading the center, his job will be to reach out to Danish and foreign companies and, with the researchers, to help find out where there is potential for starting new businesses. A 2-year seed funding grant of 11M EUR from the Innovation Fund Denmark enables the hiring of new employees with business and engineering backgrounds, as well as researchers.

According to Isaksen, the Center will engage with existing businesses, Danish as well as international companies, to develop new products and lay the foundation for new businesses. On April 15, Qubiz held a kick-off event that included seven elevator-pitches presenting potential startups—two of these have now being established and more are on the way.

Entanglement Made Simple

Posted by in category: quantum physics

Quantum entanglement is thought to be one of the trickiest concepts in science, but the core issues are simple. And once understood, entanglement opens up a richer understanding of concepts such as the “many worlds” of quantum theory.

Unzipping The Quantum-Classical Boundary

Posted by in categories: computing, quantum physics

More highlights around the correlation of Data Compression and Quantum Entanglement. I do believe as we move forward with Quantum Computing (QC) that we will discover many other correlations and re-usage of existing technology principles with Quantum Computing.


Does this data belong in the classical or the quantum world? Run it through a zip compression program to find out!

Researchers create a first frequency comb of time-bin entangled qubits

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

Quantum mechanics, with its counter-intuitive rules for describing the behavior of tiny particles like photons and atoms, holds great promise for profound advances in the security and speed of how we communicate and compute.

Now an international team of researchers has built a chip that generates multiple frequencies from a robust quantum system that produces time-bin entangled photons. In contrast to other quantum state realizations, entangled photons don’t need bulky equipment to keep them in their quantum state, and they can transmit quantum information across long distances. The new device creates entangled photons that span the traditional telecommunications spectrum, making it appealing for multi-channel quantum communication and more powerful quantum computers.

“The advantages of our chip are that it’s compact and cheap. It’s also unique that it operates on multiple channels,” said Michael Kues, Institut National de la Recherche Scientifique (INRS), University of Quebec, Canada.

Does Quantum Weirdness Arise When Parallel Classical Worlds Repel?

Posted by in categories: cosmology, quantum physics

With that goal in mind, a few years back, Wiseman began to ponder what would happen if multiple worlds not only existed, but could influence each other. Within these worlds even objects on the smallest scales obey the plain old rules that Isaac Newton devised to explain force and motion. A classical law is also used to describe the forces that the parallel worlds exert on each other. “Ours is a new picture of reality at the atomic scale,” Hall says, adding that they believe it to be “both elegant in principle, and useful for calculations in practice.”

The universe, where space-time becomes discrete

Posted by in category: quantum physics

In quantum gravity, classical physics and quantum mechanics are at odds: scientists are still uncertain how to reconcile the quantum “granularity” of space-time at the Planck scale with the theory of special relativity. In their attempts to identify possible tests of the physics associated with this difficult union, the most commonly studied scenario is the one that implies violations of “Lorentz invariance”, the principle underlying special relativity. However, there may be another approach: to salvage special relativity and to reconcile it with granularity by introducing small-scale deviations from the principle of locality. A recent theoretical study just published in Physical Review Letters and led by the International School for Advanced Studies (SISSA) in Trieste has analysed such a model demonstrating that it can be experimentally tested with great precision. The team is already collaborating on developing an experiment, which will take place at the LENS (European Laboratory for Non-linear Spectroscopy) in Florence, some members of which have also taken part in the theoretical study.

Our experience of space-time is that of a continuous object, without gaps or discontinuities, just as it is described by classical physics. For some models however, the texture of space-time is “granular” at tiny scales (below the so-called Planck scale, 10–33 cm), as if it were a variable mesh of solids and voids (or a complex foam). One of the great problems of physics today is to understand the passage from a continuous to a discrete description of spacetime: is there an abrupt change or is there gradual transition? Where does the change occur?

The separation between one world and the other creates problems for physicists: for example, how can we describe gravity – explained so well by – according to quantum mechanics? Quantum gravity is in fact a field of study in which no consolidated and shared theories exist as yet. There are, however, “scenarios”, which offer possible interpretations of quantum gravity subject to different constraints, and which await experimental confirmation or confutation.
