Radar that can spot stealth aircraft and other quantum innovations could give their militaries a strategic edge.

Dan Shechtman has the rare honour of possessing a Nobel Prize for ‘nonsense’.

It’s been nearly four decades since he set out to convince the chemist community of a discovery most considered impossible – a material called a quasicrystal. Now we have just observed a brand new variety of these once ‘impossible’ materials for the first time, one based on a single unit.

Chemists from Brown University have described the successful creation of a self-constructing lattice structure based on a strangely shaped quantum dot.

Yale University physicists suggest that Schrödinger’s cat can exist — alive or dead — in two boxes at once, a finding that could help further the development of reliable quantum computers.

Researchers from MIT and elsewhere have recorded, for the first time, the “temporal coherence” of a graphene qubit—meaning how long it can maintain a special state that allows it to represent two logical states simultaneously. The demonstration, which used a new kind of graphene-based qubit, represents a critical step forward for practical quantum computing, the researchers say.

Superconducting quantum bits (simply, qubits) are artificial atoms that use various methods to produce bits of quantum information, the fundamental component of quantum computers. Similar to traditional binary circuits in computers, qubits can maintain one of two states corresponding to the classic binary bits, a 0 or 1. But these qubits can also be a superposition of both states simultaneously, which could allow quantum computers to solve complex problems that are practically impossible for traditional computers.

The amount of time that these qubits stay in this superposition state is referred to as their “coherence time.” The longer the coherence time, the greater the ability for the qubit to compute complex problems.

To save the tamper-proof ledger from quantum-enabled hackers, the two technologies will join forces. If they don’t, data is at risk.

Quantum computing will break most of the encryption schemes on which we rely today. These five tips will help you get ready.

Search on the phrase “quantum computing,” and you’ll find a furious debate. On the one hand, you’ll read breathless articles predicting groundbreaking advances in artificial intelligence, genomics, economics, and pretty much every field under the sun. On the other, you’ll find the naysayers: It’s all hype. Large-scale quantum computers are still decades away — if they’re possible at all. Even if they arrive, they won’t be much faster than standard computers except for a tiny subset of problems.

There’s one area, however, where you’ll find all sides agree: Quantum computing will break most of the encryption schemes on which we rely today. If you’re responsible for your organization’s IT or security systems, and that sentence made the hair on the back of your neck stand up, good. To get ready for a post-quantum world, you should be thinking about the problem now.

Researchers in the field of quantum communication have recently made great strides, taking us closer to a perfectly secure method of communication.

For years, researchers struggled to find ways to amplify quantum signals, store large amounts of quantum data, and allow for more than two nodes in a quantum network. However, in the last two months, solutions to all three of these problems have been found using the bizarre properties of the quantum world, in particular quantum entanglement.

Now that these hurdles have been overcome, quantum networks and even a quantum internet seem like real possibilities.

These dimensions are the most likely source of a working theory of quantum gravity, which could help us understand the origins of the universe.

This new law was signed just as a partial US government shutdown began.

The new National Quantum Initiative Act will give America a national masterplan for advancing quantum technologies.

The news: The US president just signed into law a bill that commits the government to providing $1.2 billion to fund activities promoting quantum information science over an initial five-year period. The new law, which was signed just as a partial US government shutdown began, will provide a significant boost to research, and to efforts to develop a future quantum workforce in the country.
