Quantum hardware is starting to hit a wall that has little to do with flashy new qubit designs and everything to do with how precisely those qubits are tuned. As devices scale, tiny errors in charge ...

Predicting the behavior of many interacting quantum particles is a complicated process but is key to harness quantum computing for real-world applications. Researchers have developed a method for ...

A couple of weeks ago, the APS's Physics ran a piece titled Traveling with a Quantum Salesman, about a quantum computing approach to the famous "Traveling Salesman" problem. I saw the headline, and ...

The D-Wave quantum annealer isn’t a general-purpose computer, in that it can only solve a set of problems that can be structured as energy minimizations. And even on those problems, D-Wave employees ...

She had just solved a major problem in quantum computation, the study of computers that derive their power from the strange laws of quantum physics. Combined with her earlier papers, Mahadev’s new ...

Quantum states are notoriously fragile, and can be destroyed simply through interactions, measurements, and exposure to their ...

Quantum computers are fragile miracles of physics that are unreliable, cost-prohibitive, and more error-prone than a shortstop with no depth perception. But, if we ever want to get to Star Trek levels ...
