In particular, if we immediately measure the samequantumbitagain, we always get the same answer as the first time.
From theCambridge English Corpus
Now let us see what happens if we measure the secondquantumbitafter the first one.
From theCambridge English Corpus
Sometimes, we need to consider a permutation of quantum bits, such as exchanging the first with the secondquantumbitin a sequence.
From theCambridge English Corpus
The situation is more complex if more than onequantumbitis involved.
From theCambridge English Corpus
This occurs when we try to 'observe' the value of aquantumbitand convert it into a classical bit.
From theCambridge English Corpus
Note that this observation implies that there is effectively no difference between 'discarding' aquantumbitand simply 'forgetting' thequantumbit(by dropping any reference to it).
From theCambridge English Corpus
In particular, it is not observable whether a 'forgotten'quantumbithas been collapsed or not.
From theCambridge English Corpus
Quantum data is manipulated in terms of arrays ofquantumbitreferences.
From theCambridge English Corpus
This property can be used to send two classical bits along a channel that can hold a singlequantumbit, in the presence of a pre-existing shared entangled quantum state.
From theCambridge English Corpus
Quantum bits can be allocated and discarded; here it is understood that allocating aquantumbitmeans to request an unused quantum bit from the operating system.
From theCambridge English Corpus
The quantum device provides a potentially large number of individually addressable quantum bits.
From theCambridge English Corpus
Unitary transformations can be used to create quantum superpositions, and can also be used to create entanglement between quantum bits.
From theCambridge English Corpus
For instance, distinctness checks are necessary because quantum operators can only be applied to lists of distinct quantum bits.
From theCambridge English Corpus
Thus, the length of a list of quantum bits is a classically known quantity.
From theCambridge English Corpus
The operating system keeps a list of quantum bits that are currently in use by each process.
From theCambridge English Corpus
Typically, the quantum device will implement a fixed, finite set of unitary transformations that operate on one or two quantum bits at a time.
