virtual bitLenInt Qrack::QUnit::Compose ( QInterfacePtr  toCopy)
inlinevirtual

Combine another QInterface with this one, after the last bit index of this one.

"Compose" combines the quantum description of state of two independent QInterface objects into one object, containing the full permutation basis of the full object. The "inputState" bits are added after the last qubit index of the QInterface to which we "Compose." Informally, "Compose" is equivalent to "just setting another group of qubits down next to the first" without interacting them. Schroedinger's equation can form a description of state for two independent subsystems at once or "separable quantum subsystems" without interacting them. Once the description of state of the independent systems is combined, we can interact them, and we can describe their entanglements to each other, in which case they are no longer independent. A full entangled description of quantum state is not possible for two independent quantum subsystems until we "Compose" them.

"Compose" multiplies the probabilities of the indepedent permutation states of the two subsystems to find the probabilites of the entire set of combined permutations, by simple combinatorial reasoning. If the probablity of the "left-hand" subsystem being in |00> is 1/4, and the probablity of the "right-hand" subsystem being in |101> is 1/8, than the probability of the combined |00101> permutation state is 1/32, and so on for all permutations of the new combined state.

If the programmer doesn't want to "cheat" quantum mechanically, then the original copy of the state which is duplicated into the larger QInterface should be "thrown away" to satisfy "no clone theorem." This is not semantically enforced in Qrack, because optimization of an emulator might be acheived by "cloning" "under-the-hood" while only exposing a quantum mechanically consistent API or instruction set.

Returns the quantum bit offset that the QInterface was appended at, such that bit 5 in toCopy is equal to offset+5 in this object.

◆ Decompose() [1/3]

virtual void Qrack::QUnit::Decompose ( bitLenInt  start,
QInterfacePtr  dest 
)
inlinevirtual

Minimally decompose a set of contiguous bits from the separably composed unit, into "destination".

Minimally decompose a set of contigious bits from the separably composed unit. The length of this separable unit is reduced by the length of bits decomposed, and the bits removed are output in the destination QInterface pointer. The destination object must be initialized to the correct number of bits, in 0 permutation state. For quantum mechanical accuracy, the bit set removed and the bit set left behind should be quantum mechanically "separable."

Like how "Compose" is like "just setting another group of qubits down next to the first," if two sets of qubits are not entangled, then "Decompose" is like "just moving a few qubits away from the rest." Schroedinger's equation does not require bits to be explicitly interacted in order to describe their permutation basis, and the descriptions of state of separable subsystems, those which are not entangled with other subsystems, are just as easily removed from the description of state. (This is equivalent to a "Schmidt decomposition.")

If we have for example 5 qubits, and we wish to separate into "left" and "right" subsystems of 3 and 2 qubits, we sum probabilities of one permutation of the "left" three over ALL permutations of the "right" two, for all permutations, and vice versa, like so:

\( P(|1000>|xy>) = P(|1000 00>) + P(|1000 10>) + P(|1000 01>) + P(|1000 11>). \)

If the subsystems are not "separable," i.e. if they are entangled, this operation is not well-motivated, and its output is not necessarily defined. (The summing of probabilities over permutations of subsytems will be performed as described above, but this is not quantum mechanically meaningful.) To ensure that the subsystem is "separable," i.e. that it has no entanglements to other subsystems in the QInterface, it can be measured with M(), or else all qubits other than the subsystem can be measured.
