Time crystal in a quantum computer

There is a huge global effort to engineer a computer capable of harnessing the power of quantum physics to carry out computations of unprecedented complexity. While formidable technological obstacles still stand in the way of creating such a quantum computer, today’s early prototypes are still capable of remarkable feats.

For example, the creation of a new phase of matter called a “time crystal.” Just as a crystal’s structure repeats in space, a time crystal repeats in time and, importantly, does so infinitely and

The next giant leap: why Boris Johnson wants to ‘go big’ on quantum computing | Computing

The technology behind everyday computers such as smartphones and laptops has revolutionised modern life, to the extent that our day-to-day lives are unimaginable without it. But an alternative method of computing is advancing rapidly, and Boris Johnson is among the people who have noticed. He will need to push the boundaries of his linguistic dexterity to explain it.

Quantum computing is based on quantum physics, which looks at how the subatomic particles that make up the universe work. Last week, the prime minister promised the UK would “go big on quantum computing” by building a general-purpose quantum computer, and

IBM announces development of 127-qubit quantum processor

IBM has announced the development of a 127-qubit quantum processor, both on its IBM Quantum page and during IBM Quantum Summit 2021. As part of its announcement, IBM also announced that computers running the new processor will be made available to IBM Quantum Network members and that the company has plans for launching two other, presumably more powerful processors it has named Osprey and Condor over the next two years. The current processor has been named Eagle.

Over the past decade, several big-name technology companies have been working hard to develop a truly functional and useful quantum

Exclusive: IBM achieves quantum computing breakthrough

IBM has created a quantum processor able to process information so complex the work can’t be done or simulated on a traditional computer, CEO Arvind Krishna told “Axios on HBO” ahead of a planned announcement.

Why it matters: Quantum computing could help address problems that are too challenging for even today’s most powerful supercomputers, such as figuring out how to make better batteries or sequester carbon emissions.

Driving the news: IBM says its new Eagle processor can handle 127 qubits, a measure of quantum computing power. In topping 100 qubits, IBM says it has reached a milestone that

First quantum computer to pack 100 qubits enters crowded race

IBM’s newest quantum-computing chip, revealed on 15 November, established a milestone of sorts: it packs in 127 quantum bits (qubits), making it the first such device to reach 3 digits. But the achievement is only one step in an aggressive agenda boosted by billions of dollars in investments across the industry.

The ‘Eagle’ chip is a step towards IBM’s goal of creating a 433-qubit quantum processor next year, followed by one with 1,121 qubits named Condor by 2023. Such

Scientists are one step closer to error-correcting quantum computers

Mistakes happen — especially in quantum computers. The fragile quantum bits, or qubits, that make up the machines are notoriously error-prone, but now scientists have shown that they can fix the flubs.

Computers that harness the rules of quantum mechanics show promise for making calculations far out of reach for standard computers (SN: 6/29/17). But without a mechanism for fixing the computers’ mistakes, the answers that a quantum computer spits out could be gobbledygook (SN: 6/22/20).

Combining the power of multiple qubits into one can solve the error woes, researchers report October 4 in Nature

D-Wave announces new hardware, compiler, and plans for quantum computing

Enlarge / The current generation of hardware.

Because quantum computing has been attempted via multiple approaches, those approaches can be a bit confusing to follow. Most quantum computing efforts go toward what are called gate-based computers, which allow you to perform logical operations on individual qubits. These are well understood theoretically and can perform a variety of calculations. But it’s possible to make gate-based systems out of different types of qubits, including photons, ions, and electronic devices called transmons, and companies have grown up around each of these hardware options.

A separate form of computing, called quantum annealing, also involves

Quantum Computer Maker Rigetti to Go Public Via $1.5 Billion SPAC Deal | Technology News

OAKLAND, Calif. (Reuters) – Quantum computer maker Rigetti & Co Inc said on Wednesday it will go public through a merger with a blank-check firm in a deal that potentially values the combined company at $1.5 billion.

This is the second quantum computer hardware maker to announce going public this year using a blank-check, or special purpose acquisition company (SPAC). Maryland-based IonQ listed on the New York Stock Exchange on Friday. SPACs are shell companies that raise funds through an initial public offering to acquire a private company, which then becomes public as a result.

Rigetti said the merger with
