Nvidia CEO Jensen Huang interviews executives from quantum computing firms at Nvidia’s annual developer conference in San Jose, California, U.S., March 20, 2025. Stephen Nellis | Reuters Nvidia CEO Jensen Huang spoke at the chipmaker’s annual conference on Thursday, aiming to walk back past comments on the decadeslong timeline needed for useful quantum computers. But…
Nvidia CEO Jensen Huang interviews executives from quantum computing firms at Nvidia’s annual developer conference in San Jose, California, U.S., March 20, 2025. Stephen Nellis | Reuters Nvidia CEO Jensen Huang on Thursday walked back comments he made in January, when he cast doubt on whether useful quantum computers would hit the market in the…
THIS ARTICLE IS republished from The Conversation under a Creative Commons license. Researchers at Microsoft have announced the creation of the first “topological qubits” in a device that stores information in an exotic state of matter, in what may be a significant breakthrough for quantum computing. At the same time, the researchers also published a…
Microsoft on Wednesday announced Majorana 1, its first quantum computing chip. The achievement comes after the company spent nearly two decades of research in the field, but Microsoft claims that building Majorana 1 required that it create an entirely new state of matter, which it is referring to as a topological state. Microsoft’s quantum chip…
D-Wave Quantum CEO Alan Baratz said Nvidia’s Jensen Huang is “dead wrong” about quantum computing after comments from the head of the chip giant spooked Wall Street on Wednesday. Huang was asked Tuesday about Nvidia’s strategy for quantum computing. He said Nvidia could make conventional chips that are needed alongside quantum computing chips, but that…
It gets better. What if B is also anchored to a quantum object that’s in a superposition of two locations? Then A’s quantum state is now smeared out in two different ways, depending on the possible locations of B. Because determining B’s quantum state determines A’s state, A and B are now entangled. Renato Renner,…
The original version of this story appeared in Quanta Magazine. It’s not easy to study quantum systems—collections of particles that follow the counterintuitive rules of quantum mechanics. Heisenberg’s uncertainty principle, a cornerstone of quantum theory, says it’s impossible to simultaneously measure a particle’s exact position and its speed—pretty important information for understanding what’s going on….
