When the bang became a bounce.

How the universe began is one of the most brain-breaking questions you could possibly ask, and the Big Bang is probably the answer most people accept. But what if the infinitely dense point from which the entire universe burst forth wasn’t the beginning of everything, but merely the middle of an ongoing cycle? That’s the theory of the Big Bounce, which suggests that the universe regularly cycles through periods of expansion and contraction, meaning the Big Bang may have been preceded by an earlier universe collapsing in on itself. A new study details how this might be possible.

The idea of the Big Bounce has been bouncing around since 1922, but explaining just how the universe transitions between expanding and contracting has always been an issue. What’s to stop a universe just contracting into a point and collapsing completely? According to researchers from Imperial College London and the Perimeter Institute for Theoretical Physics in Canada, it may be the same quantum mechanics that prevent atoms from deteriorating into nothing.

More steps forward for QC through the discovery of a versatile effective spin system suitable for quantum simulations and universal quantum computation.

Using trapped atomic ions, we demonstrate a tailored and versatile effective spin system suitable for quantum simulations and universal quantum computation. By simply applying microwave pulses, selected spins can be decoupled from the remaining system and, thus, can serve as a quantum memory, while simultaneously, other coupled spins perform conditional quantum dynamics. Also, microwave pulses can change the sign of spin-spin couplings, as well as their effective strength, even during the course of a quantum algorithm. Taking advantage of the simultaneous long-range coupling between three spins, a coherent quantum Fourier transform—an essential building block for many quantum algorithms—is efficiently realized. This approach, which is based on microwave-driven trapped ions and is complementary to laser-based methods, opens a new route to overcoming technical and physical challenges in the quest for a quantum simulator and a quantum computer.

Listen up all my QC buddies; the air force wants to hear from you. You have QC ideas for fighter jets they want you.

Guess I need to submit them some of mine.

The Air Force wants white papers that describe new ways quantum computing could help achieve its mission, according to an amended Broad Agency Announcement posted Friday. Eventually, the government could provide a test-bed where a contractor might install, develop and test a quantum computing system, according to the announcement.

Last year, the Air Force announced it had about $40 million available to fund research into, and the eventual maintenance and installation of a quantum system — a branch of emerging computing technology that relies on the mechanics of atomic particles to process complex equations.

Another article on QC where the author is not well connected or knowledgeable about the details on QC’s advancement on entanglement. I suggest the author to learn about the use of Synthetic Diamonds in controlling and managing entanglement plus we now have a way to detect & trace high-dimensional entanglement that I shared 20 days ago. I suggest if authors wish to write on QC please make sure that you have the latest information so that your better informed.

The computers of today have just about hit their limits, and scientists around the world are scrambling to build the first viable quantum computer — a machine that could increase processing speeds 100-million-fold.

The biggest challenge in scaling up a quantum computer is figuring out how to entangle enough quantum bits (qubits) to perform calculations, but a team of engineers in the US say they might finally have a solution.

Aalto University scientists have broken the world record by fourteen fold in the energy resolution of thermal photodetection.

The record was made using a partially superconducting microwave detector. The discovery may lead to ultrasensitive cameras and accessories for the emerging quantum computer.

Quantum theory amplified Maxwell’s revolution.

Richard Feynman’s famous diagrams weren’t just a way to do calculations. They represented a deep shift in thinking about how the universe is put together.

Google advances on QC with Chrome.

In preparation for a quantum computing future, Google is testing post-quantum algorithms in Chrome to ensure security in the future.

Glad Google is doing this because next month could be a real test when China launches its Quantum Satellite.

Today’s encryption is an arms race as digital security experts try to hold off hackers’ attempts to break open user data. But there’s a new tech on the horizon that even the NSA recognizes as crucial to protect against: quantum computing, which is expected to dramatically speed up attempts to crack some commonly-used cryptographic schemes. To get ahead of the game, Google is testing new digital security setups on single-digit populations of Chrome users.

Quantum computing is such a potential threat because it can do many more simultaneous calculations than current computers. Modern binary bits can only be in two states when electric current is run through them: 0 or 1. But the ambiguous nature of the quantum state means its elemental units (known as “qubits”) could be in either state at a time, so two could potentially be in four orientations at one time: 00, 01, 10 or 11. That ambiguity is exponential, so three qubits could be in eight at a time, and so on.

Biocomputing/ living circuit computing/ gene circuitry are the longer term future beyond Quantum. Here is another one of the many building blocks.

The tiny molecule responsible for transmitting the genetic data for every living thing on earth could be the answer to the IT industry’s quest for a more compact storage medium. In fact, researchers from Microsoft and the University of Washington recently succeeded in storing 200 MB of data on a few strands of DNA, occupying a small dot on a test tube many times smaller than the tip of a pencil.

The Internet in a Shoebox.
