The U.S. National Academies Reports on the Prospects for Quantum Computing

In November, IEEE Spectrum published an expert-written feature titled, “The Case Against Quantum Computing.” In it, the author, Mikhail Dyakonov, defended his view that practical general-purpose quantum computers would not be built anytime in the foreseeable future. As you might expect at this time of great enthusiasm for quantum computing, the article ruffled more than […]

Intel’s New Path to Quantum Computing

Intel’s director of quantum hardware, Jim Clarke, explains the company’s two quantum computing technologies The limits of Tangle Lake’s technology Silicon spin qubits and how far away they are The importance of cryogenic control electronics Top quantum computing applications What problems keeps him up at night AI vs. Quantum Computing: which will be more important? […]

A new experiment hints at surprising hidden mechanics of quantum superpositions

It is the central question in quantum mechanics, and no one knows the answer: What really happens in a superposition—the peculiar circumstance in which particles seem to be in two or more places or states at once? Now, in a forthcoming paper a team of researchers in Israel and Japan has proposed an experiment that […]

NASA’s Atomic Fridge Will Make the ISS the Coldest Known Place in the Universe

Putting NASA’s Cold Atom Lab in space will allow quantum states to last for far longer than on Earth, offering researchers unprecedented insight into the quantum realm. Later this year, a small part of the International Space Station will become 10 billion times colder than the average temperature of the vacuum of space thanks to […]

Chinese scientists develop a photonic quantum chip for boosting analog quantum computing

Chinese scientists demonstrated the first two-dimensional quantum walks of single photons in real spatial space, which may provide a powerful platform to boost analog quantum computing. They reported in a paper published on Friday in the journal Science Advances a three-dimensional photonic chip with a scale up to 49-multiply-49 nodes, by using a technique called […]

A videogame that powers quantum entanglement experiments

The random number generator Abellan wanted to use? Randos online. His group would design a game that used the 1 and 0 keys on a phone or computer keyboard as controller buttons. As people played the game, those 1’s and 0’s they’d press would change the detector settings on each of the experiments across the […]

Random quantum circuit easiest way to beat classical computer

The key question: what computation should be performed? A team of researchers is suggesting that computing the state of a random quantum circuit that exhibits chaotic behavior would be perfect for the task. Let’s delve into why that might be. Source: arstechnica

Clouds of atoms, vibrating mirrors show their quantum side

To say the quantum world is unintuitive is a staggering understatement. Particles end up in more than one place at a time, and the instances interact with each other. Decisions made after a photon has traversed an obstacle course determine the path it took through it. Entangled quantum objects can be in separate galaxies, yet […]
