By cooling atoms down to near absolute zero and then controlling them with lasers, a company has successfully created a 100-qubit quantum processor that compares to the systems developed by leading quantum players to date.
ColdQuanta, a US-based company that specializes in the manipulation of cold atoms, unveiled the new quantum processor unit, which will form the basis of the company's 100-qubit gate-based quantum computer, code-named Hilbert, launching later this year after final tuning and optimization work.
There are various different approaches to quantum computing, and among those that have risen to prominence in the last few years feature superconducting systems, trapped ions, photonic quantum computers and even silicon spin qubits.

Amazon's cloud subsidiary AWS has released its first research paper detailing a new architecture for a future quantum computer, which, if realized, could set a new standard for error correction.
The cloud company published a new blueprint for a fault-tolerant quantum computer that, although still purely theoretical, describes a new way of controlling quantum bits (or qubits) to ensure that they carry out calculations as accurately as possible.
The paper is likely to grab the attention of many experts who are working to improve quantum error correction (QEC), a field that's growing in parallel with quantum computing that seeks to resolve one of the key barriers standing in the way of realising useful, large-scale quantum computers.

A quantum computer is -- or, perhaps more accurately phrased, would be -- a wholly different order of mechanism than anything the human species has ever constructed. Today, there are working machines that perform some small part of what a full quantum computer may eventually do. Depending upon whom you ask, these are either quantum computing prototypes or "prologues" -- stepping stones toward the real thing.
Also: Why Intel's smallest spin qubit chip could be a turning point in quantum computing
The goal of quantum computing research is to discover a means of expediting the execution of long waves of instructions. Such a means would exploit an observed phenomenon of quantum mechanics that, when you write it down on paper, doesn't appear to make sense.

Why This New Quantum Computing Startup Has a Real Shot at Beating Its Competition
A startup called Quantum Circuits plans to compete with the likes of IBM, Google, Microsoft, and Intel to bring quantum computing out of the lab and into the wider world. There’s one good reason to think it might be able to beat them all.
That’s because Quantum Circuits was founded by Robert Schoelkopf, a professor at Yale, whose work in many ways has helped kick-start this exciting new era of quantum advances.
Quantum computers exploit two strange features of quantum physics, entanglement and superposition, to process information in a fundamentally different way from traditional computers. The approach allows the power of such machines to scale dramatically with even just a few quantum bits, or qubits. Those racing to build practical quantum computers are nearing the point where quantum machines will be capable of doing things that no conventional machine could—an inflection point known as quantum supremacy.
The promise of reaching such a milestone has transformed the field from a mostly academic endeavor into a high-stakes competition between the research arms of several big companies and a few startups. And everyone is using the superconducting circuits Schoelkopf pioneered.

La Chine est-elle en passe de trouver une parade contre le cyberespionnage ? Ce lundi 15 août, elle a lancé un satellite baptisé Quess (pour Quantum Experiments at Space Scale, en anglais) et équipé d’un système de communication quantique qui pourrait bien révolutionner la sécurité des communications. Ce satellite sera utilisé pour transmettre des clés de chiffrement quantiques, virtuellement impossibles à intercepter par un tiers. Il s’agit là d’une technologie de cryptage particulièrement efficace pour protéger le contenu des données et qui intéresse également les gouvernements européens, canadiens et américains.

Quantum computing is now within closer reach thanks to a major breakthrough in which scientists have demonstrated that a key building block can be assembled.
Quantum computers are based on atomic-scale quantum bits, or qubits, that can represent both 0 and 1 simultaneously, and they are expected to deliver huge performance gains over traditional computers. Realizing that potential, however, depends on the ability to build working quantum circuits.
That's where the Fredkin gate, also known as a controlled-SWAP gate, comes in. The quantum version of the classic Fredkin gate exchanges two qubits depending on the value of the third. It could be a key component of quantum circuitry, but because of the complexity involved, no one has ever managed to build one in the real world -- until now.
Whereas the Fredkin gate typically requires a circuit of five logic operations, researchers from Griffith University and the University of Queensland used the quantum entanglement of particles of light to implement the controlled-SWAP operation directly.
“Similar to building a huge wall out of lots of small bricks, large quantum circuits require very many logic gates to function," explained Raj Patel, a research fellow in Griffith's Center for Quantum Dynamics. "However, if larger bricks are used, the same wall could be built with far fewer bricks.” Learn more / En savoir plus / Mehr erfahren: http://www.scoop.it/t/21st-century-innovative-technologies-and-developments/?tag=Quantum-Computing

Finding out how to pack as many high-quality qubits as possible on a single quantum processor is a challenge that still keeps most researchers scratching their heads – but now quantum startup Rigetti Computing has come up with a radically new approach to the problem.
Instead of focusing on increasing the size of a single quantum processor, Rigetti has linked up various smaller chips together to create, instead, a modular processor that still has a higher overall qubit count.
Describing the technology as the world's "first multi-chip quantum processor", the company launched the device with the objective of reaching 80 qubits later this year, up from the current 31 qubits supported by its Aspen processor.

Chinese scientists claim to have built a quantum computer that is able to perform certain computations nearly 100 trillion times faster than the world’s most advanced supercomputer, representing the first milestone in the country’s efforts to develop the technology.
The researchers have built a quantum computer prototype that is able to detect up to 76 photons through Gaussian boson sampling, a standard simulation algorithm, the state-run Xinhua news agency said, citing research published in Science magazine. That’s exponentially faster than existing supercomputers.

IBM has launched an integrated system for quantum computing designed for scientists and businesses called IBM Q System One.
The system will be unveiled at CES 2019 with a replica of Q System One. IBM added that it will open a commercial Q Quantum Computation Center in Poughkeepsie, New York this year. It is yet to be determined how many quantum systems will be housed in one center, said Bob Sutor, vice president of IBM Q Strategy & Ecosystems.
With IBM CEO Ginni Rometty delivering a keynote at CES, Big Blue is using the conference to highlight its research and development chops and the ability to commercialize new technologies. IBM has been among the forerunners in quantum computing. Quantum computing promises to advance a whole new paradigm beyond traditional computers. The problem with quantum computing is that it needs developers to create applications for qubits, a continuous cold environment and new hardware architectures.

Google has built the world’s most advanced quantum chip
The record-setting device could beat conventional supercomputers at solving some problems.
The news: Google announced its new Bristlecone quantum chip. It contains 72 quantum bits, or qubits, which are used to perform calculations. Until now, the most advanced quantum chip, built by IBM, had 50 qubits.
Why it matters: Some researchers—including those at Google—say that quantum devices with over 50 qubits may outperform regular supercomputers at some (specific) tasks. That’s what’s known as “quantum supremacy.”
But: More recently, some research has suggested that supremacy may require rather more than 50 qubits. And if it’s to beat regular hardware, Google will have to ensure that its chip is stable and relatively error-free.

Stable quantum bits
(Nanowerk News) Milestone on the path to the quantum computer: Scientists of the University of Konstanz, Princeton University, and the University of Maryland develop a stable quantum gate for two-quantum bit systems made of silicon. The quantum gate is able to perform all necessary basic operations of the quantum computer. The electron spin of individual electrons in silicon is used as the basic storage unit ("quantum bits"). The research results were published in Science ("Quantum CNOT Gate for Spins in Silicon").
It will take quite a few years until the first quantum computers will be available in department stores. Even today, however, it has become apparent that the quantum computer will mark a big leap in computer technology. The quantum computer will be more efficient and will be able to solve problems where current computers hit a wall.
However, the quantum computer reacts much more sensitively to external disturbances than a conventional machine. Consequently, a primary goal is to create stable "quantum gates" - the basic "building block" of the quantum computer.

Robert Schoelkopf is at the forefront of a worldwide effort to build the world’s first quantum computer. Such a machine, if it can be built, would use the seemingly magical principles of quantum mechanics to solve problems today’s computers never could.
Three giants of the tech world — Google, IBM, and Intel — are using a method pioneered by Mr. Schoelkopf, a Yale University professor, and a handful of other physicists as they race to build a machine that could significantly accelerate everything from drug discovery to artificial intelligence. So does a Silicon Valley start-up called Rigetti Computing. And though it has remained under the radar until now, those four quantum projects have another notable competitor: Robert Schoelkopf.
After their research helped fuel the work of so many others, Mr. Schoelkopf and two other Yale professors have started their own quantum computing company, Quantum Circuits. MUST read to understand!!! Today’s computers store information as “bits,” with each transistor holding either a 1 or a 0. But thanks to something called the superposition principle — behavior exhibited by subatomic particles like electrons and photons, the fundamental particles of light — a quantum bit, or “qubit,” can store a 1 and a 0 at the same time. This means two qubits can hold four values at once. As you expand the number of qubits, the machine becomes exponentially more powerful. Todd Holmdahl, who oversees the quantum project at Microsoft, said he envisioned a quantum computer as something that could instantly find its way through a maze. “A typical computer will try one path and get blocked and then try another and another and another,” he said. “A quantum computer can try all paths at the same time.” Learn more / En savoir plus / Mehr erfahren: https://www.scoop.it/t/21st-century-innovative-technologies-and-developments/?&tag=Quantum-Computing

Following what Einstein called “spooky action at a distance,” entangled particles exist in a special state that allows information carried in one to be instantaneously reflected in another — a sort of quantum teleportation.
Researchers have recently made significant progress in building this quantum communication network. China launched the world’s first quantum communication satellite last year, and they’ve since been busy testing and extending the limitations of sending entangled photons from space to ground stations on Earth and then back again. They’ve also managed to store information using quantum memory. By the end of August, the nation plans to have a working quantum communication network to boost the Beijing-Shanghai internet.
Leading these efforts is Jian-Wei Pan of the University of Science and Technology of China, and he expects that a global quantum network could exist by 2030. That means a quantum internet is just 13 years away, if all goes well.
