The quantum computing company Quantinuum recently announced a quantum computer it says outperformed a landmark Google computers result 100-fold.
What exactlyisa quantum computer?
Quantum computers operate on quantum bits.

Eventually, quantum computers should be able tosolve problems that classical computers cannot.
But quantum computers dont look like ordinary computers.
Thats because their qubits are often supercooled atoms, set up in an array.

Cooled to such a degree, the atoms enter a quantum state.
For that reason, quantum computers as they currently exist are only in dedicated research and laboratory controls.
What did the Quantinuum quantum computer do?
Googles 2019 score on the cross entropy benchmark was ~.002; H2-1s score was ~.35.
The teamsresearchis currently hosted on preprint server arXiv.
What else do quantum computers do?
Thus, it appears as if quantum entanglement can generate instances which effectively look like time travel.
Quantinuum has also execute the news circuit (no pun intended).
But the systems keep getting better, and their applications are diverse (thoughsome verge on pipe dreams).
For now its relegated to research parameters, but quantum computers are slowly creating the world of tomorrow today.
News from the future, delivered to your present.
