The biological computer is an implantable device that is mainly used for tasks like monitoring the body’s activities or inducing therapeutic effects, all at the molecular or cellular level. This is made up of RNA, DNA and proteins and can also perform simple mathematical calculations.

DNA computing is a branch of computing which uses DNA, biochemistry, and molecular biology hardware, instead of the traditional silicon-based computer technologies. Research and development in this area concerns theory, experiments, and applications of DNA computing.

In many projects there comes a time when you’ll need to store some data off-line. It may be a requirement or just an improvement for your users, but you have to decide which of the available storage options you will use in your application. This article will help you choose the best one, for your app.

Introduction

HTML5 introduced a few off-line storage options. AppCache, localStorage, sessionStorage and IndexedDB. Every one of them is suitable for a specific use. For example, AppCache can boost your application or let some parts of it work without an Internet connection. Below, I will describe all of these options and show a few code snippets with example usage.

A startup makes your computer’s storage capacity seem bottomless by connecting it to the cloud.

Atomic interactions in everyday solids and liquids are so complex that some of these materials’ properties continue to elude physicists’ understanding. Solving the problems mathematically is beyond the capabilities of modern computers, so scientists at Princeton University have turned to an unusual branch of geometry instead.

Researchers led by Andrew Houck, a professor of electrical engineering, have built an electronic array on a microchip that simulates particle interactions in a hyperbolic plane, a geometric surface in which space curves away from itself at every point. A hyperbolic plane is difficult to envision—the artist M.C. Escher used hyperbolic geometry in many of his mind-bending pieces—but is perfect for answering questions about particle interactions and other challenging mathematical questions.

The research team used superconducting circuits to create a lattice that functions as a hyperbolic space. When the researchers introduce photons into the lattice, they can answer a wide range of difficult questions by observing the photons’ interactions in simulated hyperbolic space.

Mikel Sanz, of the Physical Chemistry Department of UPV/EHU, leads the theoretical group for an experiment published by the prestigious journal, Nature Communications. The experiment has managed to prepare a remote quantum state; i.e., absolutely secure communication was established with another, physically separated quantum computer for the first time in the microwave regime. This new technology may bring about a revolution in the next few years.

Within the greater European project of the Quantum Flagship, spearheaded by Mikel Sanz—researcher of the QUTIS Group of the UPV/EHU Physical Chemistry Department—an experiment has been conducted in collaboration with German and Japanese researchers who have managed to develop a protocol for preparing a remote quantum state while conducting communication in the microwave regime, “which is the frequency at which all quantum computers operate. This is the first time the possibility of doing so in this range has been examined, which may bring about a revolution in the next few years in the field of secure quantum communication and quantum microwave radars,” lead researcher in this project Mikel Sanz observes.

The preparation of a remote quantum state (known as remote state preparation) is based on the phenomenon of quantum entanglement, where sets of entangled particles lose their individuality and behave as single entities, even when spatially separated. “Thus, if two computers share this quantum correlation, performing operations on only one of them can affect the other. Absolutely secure communication can be achieved,” Sanz explains.

A trio of researchers affiliated with several institutions in the U.S. and Canada has found evidence that suggests nuclear material beneath the surface of neutron stars may be the strongest material in the universe. In their paper published in the journal Physical Review Letters, M. E. Caplan, A. Schneider, and C. J. Horowitz describe their neutron star simulation and what it showed.

Prior research has shown that when stars reach a certain age, they explode and collapse into a mass of neutrons; hence the name neutron star. And because they lose their neutrinos, neutron stars become extremely densely packed. Prior research has also found evidence that suggests the surface of such stars is so dense that the material would be incredibly strong. In this new effort, the researchers report evidence suggesting that the material just below the surface is even stronger.

Astrophysicists have theorized that as a neutron star settles into its new configuration, densely packed neutrons are pushed and pulled in different ways, resulting in formation of various shapes below the surface. Many of the theorized shapes take on the names of pasta, because of the similarities. Some have been named gnocchi, for example, others spaghetti or lasagna. Caplan, Schneider and Horowitz wondered about the density of these formations—would they be denser and thus stronger even than material on the crust? To find out, they created some computer simulations.

The quantum computing revolution is upon us.

Establish a foundation of knowledge for understanding quantum computing with this two-course online program. Starts October 7th, 2019.

Honeywell Quantum Solutions has demonstrated record-breaking high fidelity quantum operations on their trapped-ion qubits. It is a major step towards producing the world’s most powerful quantum computer. Honeywell targets an operational trapped ion quantum computer by the end of 2019.

Currently the leading trapped ion quantum computer is by the startup IonQ. There are commercial quantum annealing systems from D-Wave Systems with 2000 qubits. There are superconducting quantum computers with 16–72 qubits from Google, IBM, Intel and Rigetti Systems.
