◆ IndexedADC() [2/3]
|

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.

See QInterface::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().
Implements Qrack::QAlu.
◆ IndexedSBC() [3/3]
|
pure virtual |
Subtract from an 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 QInterface::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.)
