Meanings of classical bits in English

This means that somehow computational operations on qubits count for more than they do for classical bits.

In the Chattanooga demo, the physicists extended the distance by converting the quantum signal to classical bits.

They then fed those classical bits into a different quantum encryption system, which could reproduce the key and transmit it farther.

That might sound absurd when you compare the bare numbers: 50 qubits versus the billions of classical bits in your laptop.

Just as classical computers act on classical bits using so-called logic gates, quantum computers manipulate qubits using the quantum equivalent, known as quantum gates.

Thus, you might need just 50 entangled qubits to model quantum states that would require exponentially many classical bits-1.125quadrillion to be exact-toencode.
