Schmidt decompose a length of qubits.
virtual void Qrack::QInterface::Decompose |
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.

Add a classical integer to the register, with sign and without carry.
Subtract an integer from the register, with sign and without carry.
Because the register length is an arbitrary number of bits, the sign bit position on the integer to add is variable. Hence, the integer to add is specified as cast to an unsigned format, with the sign bit assumed to be set at the appropriate position before the cast.

Measurement gate.
Measures the qubit at "qubit" and returns either "true" or "false." (This "gate" breaks unitarity.)
All physical evolution of a quantum state should be "unitary," except measurement. Measurement of a qubit "collapses" the quantum state into either only permutation states consistent with a |0> state for the bit, or else only permutation states consistent with a |1> state for the bit. Measurement also effectively multiplies the overall quantum state vector of the system by a random phase factor, equiprobable over all possible phase angles.
Effectively, when a bit measurement is emulated, Qrack calculates the norm of all permutation state components, to find their respective probabilities. The probabilities of all states in which the measured bit is "0" can be summed to give the probability of the bit being "0," and separately the probabilities of all states in which the measured bit is "1" can be summed to give the probability of the bit being "1." To simulate measurement, a random float between 0 and 1 is compared to the sum of the probability of all permutation states in which the bit is equal to "1". Depending on whether the random float is higher or lower than the probability, the qubit is determined to be either |0> or |1>, (up to phase). If the bit is determined to be |1>, then all permutation eigenstates in which the bit would be equal to |0> have their probability set to zero, and vice versa if the bit is determined to be |0>. Then, all remaining permutation states with nonzero probability are linearly rescaled so that the total probability of all permutation states is again "normalized" to exactly 100% or 1, (within double precision rounding error). Physically, the act of measurement should introduce an overall random phase factor on the state vector, which is emulated by generating another constantly distributed random float to select a phase angle between 0 and 2 * Pi.
Measurement breaks unitary evolution of state. All quantum gates except measurement should generally act as a unitary matrix on a permutation state vector. (Note that Boolean comparison convenience methods in Qrack such as "AND," "OR," and "XOR" employ the measurement operation in the act of first clearing output bits before filling them with the result of comparison, and these convenience methods therefore break unitary evolution of state, but in a physically realistic way. Comparable unitary operations would be performed with a combination of X and CCNOT gates, also called "Toffoli" gates, but the output bits would have to be assumed to be in a known fixed state, like all |0>, ahead of time to produce unitary logical comparison operations.)

Statistical measure of masked permutation probability.
"qPowers" contains powers of 2^n, each representing QInterface bit "n." The order of these values defines a mask for the result bitCapInt, of 2^0 ~ qPowers[0U] to 2^(qPowerCount - 1) ~ qPowers[qPowerCount - 1], in contiguous ascending order. "shots" specifies the number of samples to take as if totally re-preparing the pre-measurement state. This method returns a dictionary with keys, which are the (masked-order) measurement results, and values, which are the number of "shots" that produced that particular measurement result. This method does not "collapse" the state of this QInterface. (The idea is to efficiently simulate a potentially statistically random sample of multiple re-preparations of the state right before measurement, and to collect random measurement resutls, without forcing the user to re-prepare or "clone" the state.)
