Quantum Gate 100x Faster Than Quantum Noise

Quantum computers theoretically can solve problems no regular computer might ever hope to solve. However, the key ingredients of most quantum computers—quantum bits, or qubits, tied together by quantum entanglement—are highly vulnerable to disruption from their surroundings. Now scientists in Japan have successfully executed an operation with two qubits in just 6.5 nanoseconds—the fastest ever, which may essentially outrun the effects of any outside interference.
