Detailed Description

OpenCL enhanced QEngineCPU implementation.

Constructor & Destructor Documentation

Qrack::QEngineOCL::QEngineOCL ( bitLenInt  qBitCount,
bitCapInt  initState,
std::shared_ptr< std::default_random_engine >  rgp = nullptr,
int  devID = -1,
bool  partialInit = false,
complex  phaseFac = complex(-999.0, -999.0) 
)

Initialize a Qrack::QEngineOCL object.

Specify the number of qubits and an initial permutation state. Additionally, optionally specify a pointer to a random generator engine object, a device ID from the list of devices in the OCLEngine singleton, and a boolean that is set to "true" to initialize the state vector of the object to zero norm.

"devID" is the index of an OpenCL device in the OCLEngine singleton, to select the device to run this engine on. "partialInit" is usually only set to true when this object is one of several collected in a Qrack::QEngineOCLMulti object, in which case this Qrack::QEngineOCL object might not contain the amplitude of the overall permutation state of the combined object.

virtual bitLenInt Qrack::QEngineOCL::Cohere ( QInterfacePtr  toCopy)
inlinevirtual

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

"Cohere" 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 "Cohere." Informally, "Cohere" 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 "Cohere" them.

"Cohere" 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.

void Qrack::QEngineOCL::Decohere ( bitLenInt  start,

)
virtual

Minimally decohere a set of contiguous bits from the full coherent unit, into "destination.".

Minimally decohere a set of contigious bits from the full coherent unit. The length of this coherent unit is reduced by the length of bits decohered, 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 "Cohere" is like "just setting another group of qubits down next to the first," if two sets of qubits are not entangled, then "Decohere" 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.

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:

$ prob(|(left) 1000>) = prob(|1000 00>) + prob(|1000 10>) + prob(|1000 01>) + prob(|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 to entangled 8 bit register state with a superposed index-offset-based read from classical memory.

inputStart" is the start index of 8 qubits that act as an index into the 256 byte "values" array. The "outputStart" bits would usually already be entangled with the "inputStart" bits via a IndexedLDA() operation. With the "inputStart" bits being a "key" and the "outputStart" bits being a value, the permutation state |key, value> is mapped to |key, value + values[key]>. This is similar to classical parallel addition of two arrays. However, when either of the registers are measured, both registers will collapse into one random VALID key-value pair, with any addition or subtraction done to the "value." See IndexedLDA() for context.

FOR BEST EFFICIENCY, the "values" array should be allocated aligned to a 64-byte boundary. (See the unit tests suite code for an example of how to align the allocation.)

While a QInterface represents an interacting set of qubit-based registers, or a virtual quantum chip, the registers need to interact in some way with (classical or quantum) RAM. IndexedLDA is a RAM access method similar to the X addressing mode of the MOS 6502 chip, if the X register can be in a state of coherent superposition when it loads from RAM. "IndexedADC" and "IndexedSBC" perform add and subtract (with carry) operations on a state usually initially prepared with IndexedLDA().

Set 8 bit register bits by a superposed index-offset-based read from classical memory.

"inputStart" is the start index of 8 qubits that act as an index into the 256 byte "values" array. The "outputStart" bits are first cleared, then the separable |input, 00000000> permutation state is mapped to |input, values[input]>, with "values[input]" placed in the "outputStart" register. FOR BEST EFFICIENCY, the "values" array should be allocated aligned to a 64-byte boundary. (See the unit tests suite code for an example of how to align the allocation.)

While a QInterface represents an interacting set of qubit-based registers, or a virtual quantum chip, the registers need to interact in some way with (classical or quantum) RAM. IndexedLDA is a RAM access method similar to the X addressing mode of the MOS 6502 chip, if the X register can be in a state of coherent superposition when it loads from RAM.

The physical motivation for this addressing mode can be explained as follows: say that we have a superconducting quantum interface device (SQUID) based chip. SQUIDs have already been demonstrated passing coherently superposed electrical currents. In a sufficiently quantum-mechanically isolated qubit chip with a classical cache, with both classical RAM and registers likely cryogenically isolated from the environment, SQUIDs could (hopefully) pass coherently superposed electrical currents into the classical RAM cache to load values into a qubit register. The state loaded would be a superposition of the values of all RAM to which coherently superposed electrical currents were passed.

In qubit system similar to the MOS 6502, say we have qubit-based "accumulator" and "X index" registers, and say that we start with a superposed X index register. In (classical) X addressing mode, the X index register value acts an offset into RAM from a specified starting address. The X addressing mode of a LoaD Accumulator (LDA) instruction, by the physical mechanism described above, should load the accumulator in quantum parallel with the values of every different address of RAM pointed to in superposition by the X index register. The superposed values in the accumulator are entangled with those in the X index register, by way of whatever values the classical RAM pointed to by X held at the time of the load. (If the RAM at index "36" held an unsigned char value of "27," then the value "36" in the X index register becomes entangled with the value "27" in the accumulator, and so on in quantum parallel for all superposed values of the X index register, at once.) If the X index register or accumulator are then measured, the two registers will both always collapse into a random but valid key-value pair of X index offset and value at that classical RAM address.

Note that a "superposed store operation in classical RAM" is not possible by analagous reasoning. Classical RAM would become entangled with both the accumulator and the X register. When the state of the registers was collapsed, we would find that only one "store" operation to a single memory address had actually been carried out, consistent with the address offset in the collapsed X register and the byte value in the collapsed accumulator. It would not be possible by this model to write in quantum parallel to more than one address of classical memory at a time.
