A growing body of research now treats the challenge of building large-scale quantum computers less as a single-chip engineering puzzle and more as a networking problem. The core idea: link smaller, ...

Since the 1990s, evidence has been growing that quantum computers should be able to solve a range of particularly complex computational problems, with applications in everything from supply chain ...

Scientists have established a relationship between the complexity of a problem, and the physical processes of entanglement required to solve it. “Some mathematical problems are easy. Some mathematical ...

Today, entanglement is more than a philosophical puzzle. It is a key ingredient in many of the technologies researchers hope will define the future, including quantum computing, quantum communication, ...

Light moving through a tiny silicon structure does not look dramatic. It slips down narrow waveguides etched onto a chip, guided by geometry too small to see with the naked eye. Yet in those channels, ...

A surge of funding and federal action is giving the once-futuristic technology a more immediate role in everything from ...

Teleportation is a reality in 2025 — well, at least for quantum computers. In February 2025, Oxford University demonstrated the teleportation of quantum data from one independent quantum processor to ...

Quantum entanglement—once dismissed by Albert Einstein as “spooky action at a distance”—has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum ...

Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...

This technology may or may not be a big deal. Simultaneously.

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.
