Quantum bits, or qubits, can also be entangled - the state of one qubit influences the state of another even at a considerable distance.

量子位，或称量位，也会互扰- - -即便相离甚远，某个量位的状态还是会影响另一个量位的状态。

At extremely cold temperatures, it goes quantum: it exists in an oscillating waveform spanning an excited state, an unexcited state, or both simultaneously, all controlled by electrical currents.

在极低的温度下，它发生量子：它存在于一个振荡波形中，波形可能呈现激发态、未激态、或两者同时兼具，这都取决于电流的控制。

So if we think about, for example, this red line here, which energy state or which principle quantum number do you think that our electron started in?

我们来看看，比如这里的这个红线，它是从主量子数,等于多少的能级发出的？

But transmitting single particles or, to be accurate, copying the quantum state of one particle on to another, perhaps of a different kind could one day have less science-fictional uses.

As a consequence of this additional uncertainty, if the quantum demon makes a measurement of a nucleus which forces it to choose one state or the other, he is creating new information.
