Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a manuscript for publication. Its centerpiece was an innocuous-looking equation ...

Quantum computing and its threat to current encryption and the unknown threat of powerful quantum automated by advanced AI.

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

With tech stocks benefiting from sky-high valuations, one quickly-growing corner could define the sector's next chapter. That's because quantum computing offers "extraordinary potential," according to ...

Some South Chicago residents are concerned about the economic and environmental impact the 128-acre park will have on the area. The Illinois Quantum and Microelectronics Park on Chicago’s South Side ...

A new presidential initiative called QMIT will advance the development of quantum technologies—and help ensure that they are used for good. As MIT navigates a difficult and constantly changing higher ...

Since decades quantum gravity tries to close the gap to general relativity, but all attempts remain pure theory without empirical test. The present study now extends loop quantum gravity to a verified ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Upstarts like IonQ and Rigetti Computing have boom-or-bust potential in 2026. Legacy tech players like Alphabet have a greater chance of success. Clearly, quantum computing stocks are quite volatile.

Pure-play developers like IonQ, Rigetti Computing, and D-Wave Quantum are the hottest quantum computing stocks right now. Big tech giants are also exploring quantum computing in addition to their ...
