An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...

Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the ...

Quantum walks are changing the way scientists think about computation. They use the strange and powerful rules of quantum physics—such as superposition, interference, and entanglement—to solve ...

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical billiard balls and more like quantum actors. A growing body of research now ...

Nvidia claims to have kicked off the “quantum-GPU computing era,” unveiling a way for quantum computers to interconnect with classical systems. Revealed at the chip giant’s GTC event in Washington, ...

Quantum systems tend to become less “quantum-y” as they interact with their environment. So when developing a mathematical description, it’s usually simpler just to view them as being closed off from ...

Researchers used a non-Hermitian version of the Hubbard model with spin-resolved asymmetric hopping to reveal how spin depairing creates a stable superfluid with embedded exceptional points. A stable ...
