Is the Universe Actually a Giant Quantum Computer?

Posted by in categories: computing, engineering, humor, quantum physics, space

According to MIT professor Seth Lloyd, the answer is yes. We could be living in the kind of digital world depicted in The Matrix, and not even know it.

A researcher in Mechanical Engineering at MIT, Lloyd is one of the leaders in the field of quantum information. He’s been with the field from its very conception to its sky-rocketing rise to popularity. Decades ago, the feasibility of developing quantum computing devices was challenged. Now, as quantum computation is producing actual technologies, we are only left to wonder—what kind of applications will it provide us with next?

But, first things first. In a round-table discussion with undergraduates, Lloyd speaks of his early days in the field with a touch of humor, irony, and most surprisingly—pride. When he just started to research quantum information in graduate school, most scientists told him to look into other areas. In fact, out of the postdoctoral programs he considered, not many were too invested in researching of information in quantum mechanics. Most universities and institutes were reluctant to take up quantum computing, but Murray Gell-Mann accepted Lloyd for a position at the California Institute of Technology. This is where many ideas behind quantum computation were born, and Lloyd is “excited by the popularity of the field today.”

Synopsis: Diamond Qubits Take the Stage

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

A ten-qubit system based on spins in impure diamond achieves coherence times of over a minute.

In the global race to build a quantum computer, it’s still unclear what material will make the best qubit. Companies have bet on a variety of architectures based on trapped ions, neutral atoms, superconducting circuits, and more. Now, Tim Taminiau of Delft University of Technology, Netherlands, and colleagues have demonstrated that they can manipulate magnetic spins inside diamond into the robust quantum states necessary for quantum computing. In their experiment, they entangle all possible pairs of a ten-qubit system and produce states in which seven different qubits are entangled simultaneously. They also show that individual qubits can retain quantum coherence for up to 75 s—a record for solid-state systems.

Avoiding Prejudices In The Future World Of Transhumanism

Posted by in categories: computing, cyborgs, transhumanism

It is a solid talk on an important message.


From cyborgs to the Sugababes, IT expert Robert Anderson talks about a world where the line between humans and machines becomes blurred. Drawing on his personal experiences of facing prejudices and bigotry while growing up, he shares his insight on how we can avoid repeating the mistakes of the past in order to create a society where humans and transhumans can live together in an open and equal manner. He urges us to take action now because as he says.

Future of portable electronics: Novel organic semiconductor with exciting properties

Posted by in categories: computing, solar power, sustainability

Semiconductors are substances that have a conductivity between that of conductors and insulators. Due to their unique properties of conducting current only in specific conditions, they can be controlled or modified to suit our needs. Nowhere is the application of semiconductors more extensive or important than in electrical and electronic devices, such as diodes, transistors, solar cells, and integrated circuits.

Semiconductors can be made of either organic (carbon-based) or inorganic materials. Recent trends in research show that scientists are opting to develop more organic semiconductors, as they have some clear advantages over inorganic semiconductors. Now, scientists, led by Prof Makoto Tadokoro of the Tokyo University of Science, report on the synthesis of a novel organic substance with potential applications as an n-type semiconductor. This study is published in the journal Organic and Biomolecular Chemistry. According to Prof Makoto Tadokoro, “organic semiconductor devices, unlike hard inorganic semiconductor devices, are very soft and are useful for creating adhesive portable devices that can easily fit on a person.” However, despite the advantages of organic semiconductors, there are very few known stable molecules that bear the physical properties of n-type semiconductors, compared to inorganic n-type semiconductors.

N-heteroheptacenequinone is a well-known potential candidate for materials. However, it has some drawbacks: it is unstable in air and UV-visible light, and it is insoluble in organic solvents. These disadvantages obstruct the practical applications of this substance as a semiconductor.

This Startup Raised $15 Million To Reduce Errors In Quantum Computing

Posted by in categories: computing, engineering, quantum physics

Q-CTRL, an Australian-based quantum computing software company that makes “quantum firmware,” on Tuesday announced a $15 million series A funding round led by Square Peg Capital. Sierra Ventures also participated in the round, joining existing investors Horizons Ventures, Main Sequence Ventures, and Sequoia Capital.

The primary purpose of the round, says founder and CEO Michael Biercuk, is to expand and grow the company. It currently has 25 employees and aims to double that number in the next 12 to 18 months. It’s also opening an office in Los Angeles where it hopes to add more employees and will expand its product offerings in the field of quantum sensing.

Biercuk is a professor at the University of Sydney and has been conducting research in quantum computing for over a decade. He’s particularly interested in combining the principles of control engineering to quantum computing and other systems such as quantum sensing.

Q-CTRL raises $15M for software that reduces error and noise in quantum computing hardware

Posted by in categories: computing, quantum physics

As hardware makers continue to work on ways of making wide-scale quantum computing a reality, a startup out of Australia that is building software to help reduce noise and errors on quantum computing machines has raised a round of funding to fuel its U.S. expansion.

Q-CTRL is designing firmware for computers and other machines (such as quantum sensors) that perform quantum calculations, firmware to identify the potential for errors to make the machines more resistant and able to stay working for longer (the Q in its name is a reference to qubits, the basic building block of quantum computing).

The startup is today announcing that it has raised $15 million, money that it plans to use to double its team (currently numbering 25) and set up shop on the West Coast, specifically Los Angeles.

Israeli startup is totally reinventing how cars are built

Posted by in categories: computing, food

Technology entrepreneurs delight in disrupting established industries, from textiles to healthcare to agriculture.

Changes in automotive manufacturing have been tougher to sell because no matter how many computers are put under the hood, the cars themselves “are still being built on 100-year-old concepts,” Daniel Barel, CEO of Israeli automotive startup REE, tells ISRAEL21c.

Harvard University: The Near Future of Cybernetics Transpires

Posted by in categories: biotech/medical, computing, cyborgs, neuroscience

Researchers are blurring the distinction between brain and machine, designing nanoelectronics that look, interact, and feel like real neurons. Camouflaged in the brain, this neurotechnology could offer a better way to treat neurodenerative diseases or control prosthetics, interface with computers or even enhance cognitive abilities.

Electrodes implanted in the brain help alleviate symptoms like the intrusive tremors associated with Parkinson’s disease but current probes face limitations due to their size and inflexibility. In a recent paper titled “Precision Electronic Medicine,” published in Nature Biotechnology, Shaun Patel, a faculty member at the Harvard Medical School and Massachusetts General Hospital, and Charles M. Lieber, the Joshua and Beth Friedman University Professor, argue that neurotechnology is on the cusp of a major renaissance. Throughout history, scientists have blurred discipline lines to tackle problems larger than their individual fields.

“The next frontier is really the merging of human cognition with machines,” says Patel. “Everything manifests in the brain fundamentally. All your thoughts, your perceptions, any type of disease.” He and Lieber see mesh electronics as the foundation for these machines, a way to design personalized electronic treatment for just about anything related to the brain. “Today, research focused at the interface between the nervous system and electronics is not only leading to advances in fundamental neuroscience, but also unlocking the potential of implants capable of cellular-level therapeutic targeting,” write the authors in their paper.

Human speech may have a universal transmission rate: 39 bits per second

Posted by in categories: computing, internet

This assumes information transfer between humans is frictionless, which it is not. At least not currently. We could easily address this, but no one is listening:-) QED.


Italians are some of the fastest speakers on the planet, chattering at up to nine syllables per second. Many Germans, on the other hand, are slow enunciators, delivering five to six syllables in the same amount of time. Yet in any given minute, Italians and Germans convey roughly the same amount of information, according to a new study. Indeed, no matter how fast or slowly languages are spoken, they tend to transmit information at about the same rate: 39 bits per second, about twice the speed of Morse code.

“This is pretty solid stuff,” says Bart de Boer, an evolutionary linguist who studies speech production at the Free University of Brussels, but was not involved in the work. Language lovers have long suspected that information-heavy languages—those that pack more information about tense, gender, and speaker into smaller units, for example—move slowly to make up for their density of information, he says, whereas information-light languages such as Italian can gallop along at a much faster pace. But until now, no one had the data to prove it.
