Simmons says that silicon quantum processors offer an inherent advantage in scaling, too. Generating numerous registers on a ...

Quantum entanglement, the invisible connection between particles that entwines them in such a way that they act as one, has fascinated scientists for decades. It is also one of the most important ...

Operating at room temperature, this nanoscale device leverages silicon photonics to achieve high-performance spin control, essential for quantum communication.

For the past decade, quantum computing has struggled to balance promise and practicality. While the world’s most advanced systems remain engineering marvels, they’re bedeviled by the same flaw: the ...

Quantum materials can behave in surprising ways when many tiny spins act together, producing effects that don’t exist in single particles.

For two decades, a deceptively simple question has split condensed‑matter physicists: do the electrons in gold quietly align their spins, or is the metal as magnetically featureless as textbooks claim ...

When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now shown that the Kondo effect behaves very differently depending on spin ...

Cracking quantum computing isn’t a matter of upgrading existing computers. It’s an entirely separate approach to computing that relies on the principles of quantum physics. “A fighter jet is not a ...

QCI has established an early mover’s advantage in photonic quantum chips. These chips could be easier to scale than electron or ion-driven systems. But it could still take years for QCI to ...

IonQ expects its computing power to increase by approximately 20,000 times by 2030. Rigetti anticipates a tenfold increase in its computing power by 2027. Both stocks are speculative, but one has a ...
