n.量子比特（量子计算器中的最小信息单位，qubit的复数）
Longer entanglement allows the qubits to process more complex problems.───更长的互扰使得量位可以处理更复杂的问题。
Four qubits can represent 16 values, and so on.───四个量子可以代表16个值，依此类推。
A quantum computer would use entangled qubits to process information.───量子计算机可以利用扰动量位来处理数据。
Such a system might be extended in multiple relays, so that the qubits in a key could be transmitted across continents or oceans.───这样的传送系统可以藉由多重中继器而扩展，因此钥匙里的量子位元可以越陌度阡、横跨大陆或海洋。
They do so by encoding all possible permutations in the form of a small number of "qubits" .───解决之道在于将所有可能的排列编译为少数的量子位。
Many thousands of qubits would be necessary to make quantum computing useful.───要想让量子计算具有使用价值，数千个量子位是必要的。
The researchers controlled the system using a microwave 'tone' with a frequency that causes the qubits to become entangled.───研究人员使用一种微波来控制该系统，其频率可使量位互扰。
An eavesdropper might sabotage a receiver's detector, causing qubits received from a sender to leak back into a fiber and be intercepted.───窃听者可以破坏接收者的侦测器，让来自传送者的量子位元回漏到光纤而被拦截。
A software algorithm, known as privacy amplification, helps to guard against this possibility by masking the values of the qubits.───有一种称为「加强隐私」（privacyamplification）的演算软体，便可以伪装量子位元的值，以防止资料被窃取。
The third basic requirement is the ability to devise at least one type of logic gate between qubits.
Quantum communication is an unconditional secure communication manner using qubits to transmit information.
It can take the same form as classical logic gates—the AND and OR gates that are the building blocks of conventional processors—but it must also act on the superposition states unique to qubits.
To make a conditional logic gate between two ion qubits, we require a coupling between them—in other words, we need them to talk to each other.
Once this occurs, even though the ions may be widely separated, the manipulation of one of the qubits will affect the other, allowing the construction of a CNOT logic gate.
We investigate the case in which the prior entanglement is not maximal and the initial state of the entangled pair of qubits being used for the dense coding is a mixed state.
The SPECTRUM line shows us where the qubits for a have been allocated in the quantum heap; in this case the 0-bit of a is the rightmost qubit in the heap.
Encoding qubits on the singlet state and the triplet state can protect qubits from low-frequency noise and suppress the dominant source of decoherence from hyperfine interactions.
