What Is A Quantum Computer? The 30,000 Foot Overview

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

If you replace classical bits with qubits, though, you go back to only needing one per spin in the system, because all the quantum stuff comes along for free. You don&s;t need extra bits to track the superposition, because the qubits themselves can be in superposition states. And you don&s;t need extra bits to track the entanglement, because the qubits themselves can be entangled with other qubits. A not-too-big quantum computer— again, 50–100 qubits— can efficiently solve problems that are simply impossible for a classical computer.

These sorts of problems pop up in useful contexts, such as the study of magnetic materials, whose magnetic nature comes from adding together the quantum spins of lots of particles, or some types of superconductors. As a general matter, any time you&s;re trying to find the state of a large quantum system, the computational overhead needed to do it will be much less if you can map it onto a system of qubits than if you&s;re stuck using a classical computer.

So, there&s;s your view-from-30,000-feet look at what quantum computing is, and what it&s;s good for. A quantum computer is a device that exploits wave nature, superposition, and entanglement to do calculations involving collective mathematical properties or the simulation of quantum systems more efficiently than you can do with any classical computer. That&s;s why these are interesting systems to study, and why heavy hitters like Google, Microsoft, and IBM are starting to invest heavily in the field.

Scientists achieve first ever acceleration of electrons in plasma waves

Posted by in category: particle physics

The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) near Geneva, Switzerland is said to be the largest particle accelerator in the world. The accelerator occupies a tunnel 27 kilometers in circumference as deep as 175 meters beneath the French-Swiss border. The facility has helped scientists uncover the Higgs boson, the last particle predicted by the Standard Model, in 2012.

Photo-catalytic Killing of HeLa Cancer Cells Using Facile Synthesized Pure and Ag Loaded WO3 Nanoparticles

Posted by in categories: biotech/medical, genetics, health, nanotechnology

The cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells, and in most of the cases develop into malignant masses of tissues called tumors, and it is the leading causes of mortality and a major public health challenge worldwide. In normal body, genes in the cell nucleus, containing long strings of DNA (deoxyribonucleic acid) regulate the controlled division and function of cells and any damage to DNA causes the mutation of genes, which in turn triggers the uncontrolled division of abnormal cells, leading to the damage of vital organs. Cancer cells can detach from the original mass of tumor and migrate to new locations through blood and lymphatic system and also cancer cells produce enzymes that are capable of breaking the normal cells. For cancer diagnostics, the conventional histopathological and radiological examinations are still used for evaluating the clinical and pathologic staging, needed for cancer treatments. Depends on the stage of cancer development, different treatment options like chemotherapy, radiation therapy, stem cell transplant, immunotherapy, hormone therapy, targeted drug therapy and surgery are advised. The major disadvantages of the available advanced treatment options include non localized invasion to other body parts, intolerable cytotoxicity, unsystematic distribution of antitumor agents, immune to chemical agents, low bioavailability and limited option to evaluate the tumor cell response to therapies4,5. In spite of the drawbacks of these advanced treatment options, cancer is curable if it is diagnosed at an early stage.

Phototherapy has been used for the treatment of jaundice, cancer, dermatological conditions, and ophthalmological disorders by simply using the light of certain selected wavelength. Photodynamic therapy, on the other hand is a method of photosensitizing the action of drugs to kill cancer cells, but the major drawback of this treatment is that most of the drugs used for photodynamic therapy remain activated for a long time, leading to overdose to damage non cancer cells. In the photo-catalytic process, no drug is used, instead the nontoxic semiconductor photo-catalyst like WO3 generates electron hole pairs, when it is exposed to the light of appropriate wavelength and these photo-generated charge carriers mediate oxidation and reduction reactions in the cancer cell to eliminate them.

Spontaneous genetic mutations in the womb may drive the majority of dementia cases

Posted by in categories: biotech/medical, genetics, neuroscience

New research, led by scientists at the University of Cambridge, suggests spontaneous DNA mutations that occur when a baby’s brain is growing in the womb may help explain why so many people develop dementia without having any prior family history with the disease.

Shocking stories about monitoring Yellowstone National Park

Posted by in category: futurism

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week’s contribution is from Beth Bartel and Tim Dittman, from the non-profit UNAVCO consortium in Boulder, Colorado.

About 18 miles west of the Yellowstone National Park boundary in Idaho, UNAVCO field engineer Tom Lyman surveys the damage at GPS station P361 on Sawtell Peak. This is an important site, not only because it is located close to active faults in the Yellowstone region, but also because it serves as a data relay for four additional nearby GPS stations. None of the GPS equipment is transmitting data.

UNAVCO, a member of the Yellowstone Volcano Observatory consortium, is responsible for maintaining the deformation network in and around Yellowstone. In Yellowstone National Park alone this network includes 14 GPS stations and six borehole geophysics stations. All the data are free and open access.

Researchers Find Oldest Evidence of Animal Life on Earth

Posted by in category: futurism

The oldest clue of animal life, dating back at least 100 million years before the Cambrian period, when most major types of animals appear, has been found by University of California, Riverside (UCR) researchers.

The researchers have been tracking molecular signs of animal life, called biomarkers, as far back as 660–635 million years ago during the Neoproterozoic Era. They found a steroid compound produced only by sponges, which are among the earliest forms of animal life, in ancient rocks and oils from Oman, Siberia, and India.

The biomarker identified, a steroid compound named 26-methylstigmastane (26-mes), has a unique structure that is currently only known to be synthesized by certain species of modern sponges called demosponges.

New treatment prevents transplant rejection

Posted by in category: biotech/medical

A new treatment strategy could increase the success rate of stem cell transplants, according to University of Queensland researchers.

The approach removes the need for donor matching and the use of immunosuppressant drugs to prevent rejection, and could make stem cell treatment accessible to more patients.

UQ Diamantina Institute researcher Dr Jatin Patel said researchers found immunosuppressant drugs had a negative impact on the transplanted stem cells.
