‘Milestone’ Evidence for Anyons, a Third Kingdom of Particles

Anyons, as they’re known, don’t behave like either fermions or bosons; instead, their behavior is somewhere in the middle.If the wave functions are identical, your quantum particles are bosons.

Revolt! Scientists Say They're Sick of Quantum Computing's Hype

While Bermejo-Vega thinks Google’s demonstration does provide scientific value of the technology’s viability, she emphasizes their success was “narrow.” In addition, all quantum computers, including Google’s, perform inconsistently because they are prone to errors that researchers don’t know how to correct.

Microsoft Is Taking Quantum Computers to the Cloud

Microsoft’s model is more like the existing computing industry, where cloud providers allow customers to choose processors from companies such as Intel and AMD, says William Hurley, CEO of startup Strangeworks, which offers a service for programmers to build and collaborate with quantum computing tools from IBM, Google, and others.

Quantum Computing Is Here! But Also Not Really

Quantum Computing Is Here! But Also Not Really

“We compare it to a Sputnik moment,” Hartmut Neven, the executive who started Google’s quantum program in 2006, told reporters, wearing a silvery jacket and boots apt for the space analogy.

IBM Says Google’s Quantum Leap Was a Quantum Flop

IBM Says Google’s Quantum Leap Was a Quantum Flop

In 2017, after the company said it was closing in on the milestone, IBM researchers published results that appeared to move the goalposts.Soon, researchers from Chinese ecommerce company Alibaba, which has its own quantum computing program, released analysis claiming that the device could not do what Google said.

WIRED25: Stories of People Who Are Racing to Save Us

For years, even before the team’s creation, Galperin and fellow EFF researcher Cooper Quintin investigated a hacking operation that planted spyware on the computers of journalists and opposition figures in Kazakhstan.

Why I Coined the Term ‘Quantum Supremacy’

Why I Coined the Term ‘Quantum Supremacy’

They used a device with 53 qubits (the quantum analogues of a classical computer’s bits), and they report that it took just minutes to perform quantum computations that would take today’s most powerful supercomputers thousands of years.

Even Huge Molecules Follow the Quantum World's Bizarre Rules

Even Huge Molecules Follow the Quantum World's Bizarre Rules

Physicists have observed atoms, electrons, and other minutiae transitioning between wave-like and particle-like states for decades.It’s an extremely difficult experiment to pull off, he says, because quantum objects are delicate, transitioning suddenly from their wavelike state to their particle-like one via interactions with their environment.

The Surprisingly Cozy Truths of Sleeping in Space

The Surprisingly Cozy Truths of Sleeping in Space

It’s a far cry from the spacious beds we have on Earth, but it’s still better than the shared sleeping compartment on the space shuttle, which Mike Massimino , a former NASA astronaut, describes as “a big slumber party.” The trick, Massimino says, was to remember to strap your sleeping bag to the wall so your body wouldn’t drift around during the night.

Quantum Darwinism Could Explain What Makes Reality Real

Quantum Darwinism Could Explain What Makes Reality Real

One of the most remarkable ideas in this theoretical framework is that the definite properties of objects that we associate with classical physics—position and speed, say—are selected from a menu of quantum possibilities in a process loosely analogous to natural selection in evolution: The properties that survive are in some sense the “fittest.” As in natural selection, the survivors are those that make the most copies of themselves.

Why Big Banks Could Soon Jump on the Quantum Bandwagon

Why Big Banks Could Soon Jump on the Quantum Bandwagon

The experiment was too simplistic to be useful for banks, but it’s a promising proof of concept; once bigger and smoother-running quantum computers are available, the researchers say, they hope to execute the algorithm faster than conventional machines.

Quantum Computers Could Be True Randomness Generators

Quantum Computers Could Be True Randomness Generators

In our case, to randomly output a 50-bit string, you can build a quantum circuit that puts 50 qubits, taken together, into a superposition of states that captures the distribution you’d like to re-create.

Noisy Quantum Computers Could Be Good for Chemistry Problems

Noisy Quantum Computers Could Be Good for Chemistry Problems

However, for chemistry simulations, the noise would be representative of the physical environment in which both the chemical system (e.g., a molecule) and the quantum device exist.

Inside the High-Stakes Race to Make Quantum Computers Work

Federico Carminati, a physicist at CERN, admits that today’s quantum computers wouldn't give researchers anything more than classical machines, but, undeterred, he’s started tinkering with IBM’s prototype quantum device via the cloud while waiting for the technology to mature.

Quantum Physics Could Protect the Grid From Hackers—Maybe

Quantum Physics Could Protect the Grid From Hackers—Maybe

“It’s like working on a car with its engine running.” Sungjin Kim/Getty Images Cybersecurity experts have sounded the alarm for years: Hackers are ogling the U.S. power grid. Peters’s group thinks that a utility company could use quantum-encrypted data to communicate with their hardware.

Is the Universe a Hologram? Maybe! This Math Trick Shows How

There is “tantalizing evidence,” said Xi Dong of the University of California, Santa Barbara, who led the research, that the new model is a piece of “a unified framework for quantum gravity in de Sitter [space].” Dong and co-authors Eva Silverstein of Stanford University and Gonzalo Torroba of the Bariloche Atomic Center in Argentina constructed a hologram of dS space by taking two AdS universes, cutting them, warping them and gluing their boundaries together.
