New quantum dot microscope shows electric potentials of individual atoms

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

A team of researchers from Jülich in cooperation with the University of Magdeburg has developed a new method to measure the electric potentials of a sample at atomic accuracy. Using conventional methods, it was virtually impossible until now to quantitatively record the electric potentials that occur in the immediate vicinity of individual molecules or atoms. The new scanning quantum dot microscopy method, which was recently presented in the journal Nature Materials by scientists from Forschungszentrum Jülich together with partners from two other institutions, could open up new opportunities for chip manufacture or the characterization of biomolecules such as DNA.

The positive atomic nuclei and negative electrons of which all matter consists produce electric potential fields that superpose and compensate each other, even over very short distances. Conventional methods do not permit quantitative measurements of these small-area fields, which are responsible for many material properties and functions on the nanoscale. Almost all established methods capable of imaging such potentials are based on the measurement of forces that are caused by electric charges. Yet these forces are difficult to distinguish from other forces that occur on the nanoscale, which prevents quantitative measurements.

Four years ago, however, scientists from Forschungszentrum Jülich discovered a method based on a completely different principle. Scanning quantum dot microscopy involves attaching a single organic molecule—the quantum dot—to the tip of an atomic microscope. This molecule then serves as a probe. “The molecule is so small that we can attach individual electrons from the tip of the atomic force microscope to the molecule in a controlled manner,” explains Dr. Christian Wagner, head of the Controlled Mechanical Manipulation of Molecules group at Jülich’s Peter Grünberg Institute (PGI-3).

CRISPR used to build dual-core computers inside human cells

Posted by in categories: bioengineering, biotech/medical, computing, genetics

The CRISPR gene-editing system is usually known for helping scientists treat genetic diseases, but the technology has a whole range of possible uses in synthetic biology too. Now researchers at ETH Zurich have used CRISPR to build functional biocomputers inside human cells.

Quantum Computing, Now and in the (Not Too Distant) Future

Posted by in categories: computing, quantum physics

To date, more than 110,000 users have run more than 7 million experiments on the public IBM Q Experience devices, publishing more than 145 third-party research papers based on experiments run on the devices. The IBM Q Network has grown to 45 organizations all over the world, including Fortune 500 companies, research labs, academic institutions, and startups. This goal of helping industries and individuals get “quantum ready” with real quantum hardware is what makes IBM Q stand out.

SF: What are the main technological hurdles that still need to be resolved before quantum computing goes mainstream?

JW: Today’s approximate or noisy quantum computers have a coherence time of about 100 microseconds. That’s the time in which an experiment can be run on a quantum processor before errors take over. Error mitigation and error correction will need to be resolved before we have a fault-tolerant quantum computer.

My writeup of the coolest and session at MWC Barcelona where there was a live on-stage demonstration of a human chip being implanted into someone’s hand.


Welcome to the future, where we already transhuman and microchipped. Will you merge with technology or be left behind?

Microsoft Is Building an All-In-One DNA Data Storage Device

Posted by in categories: computing, genetics

The modern world is facing a tsunami of data. DNA is emerging as an ultra-compact way of storing it all, and now researchers supported by Microsoft have created the first system that can automatically translate digital information into genetic code and retrieve it again.

In 2018 we created 33 zettabytes (ZB)—33 trillion gigabytes—of data, according to analysts at IDC, and they predict that by 2025 that figure will rise to 175 ZB. It’s been estimated that if we were to store all our information in flash drives, by 2040 it would require 10 to 100 times the global supply of chip-grade silicon.

DNA, on the other hand, is so compact it could shrink a data center to the size of a few dice. But for that to become practical we need a DNA-based equivalent of a hard drive that lets you upload and download data in a simple and intuitive way.

A Data Storage Revolution? DNA Can Store Near Limitless Data in Almost Zero Space

Posted by in categories: computing, information science, space

In the age of big data, we are quickly producing far more digital information than we can possibly store.

Last year, $20 billion was spent on new data centers in the US alone, doubling the capital expenditure on data center infrastructure from 2016.

And even with skyrocketing investment in data storage, corporations and the public sector are falling behind.

Wild New Discovery Shows How We Can Switch Majorana Fermions On And Off

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

The particle known as a Majorana fermion is as mysterious and uncontrollable as it is unique. It’s the only known particle that is also its own antiparticle, and has properties that make it an alluring candidate for qubits, the basic unit of information in a quantum computer.

Harnessing that potential, however, is easier said than done — Majorana fermions are slippery little suckers. But a team of particle physicists now reports they’ve found a way to control them.

“We now have a new way to engineer Majorana quasiparticles in materials,” said physicist Ali Yazdani of Princeton University. “We can verify their existence by imaging them and we can characterise their predicted properties.”

Mysterious Majorana quasiparticle is now closer to being controlled for quantum computing

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

As mysterious as the Italian scientist for which it is named, the Majorana particle is one of the most compelling quests in physics.

Its fame stems from its strange properties—it is the only particle that is its own antiparticle—and from its potential to be harnessed for future quantum computing.

In recent years, a handful of groups including a team at Princeton have reported finding the Majorana in various materials, but the challenge is how to manipulate it for quantum computation.
