MultiplyByConstantModN

Extends:

BasicGateBasicMathGate → MultiplyByConstantModN

Multiply a quantum number represented by a quantum register by a constant modulo N.

The number is stored from low- to high-bit, i.e., qunum[0] is the LSB.

Example:

qunum = eng.allocateQureg(5) # 5-qubit number
X | qunum[2] # qunum is now equal to 4
MultiplyByConstantModN(3,5) | qunum # qunum is now 2.

Override:

BasicMathGate#constructor

Params:

NameTypeAttributeDescription
a number

Number by which to multiply a quantum register (0 <= a < N).

N number

Number modulo which the multiplication is carried out.

It also initializes its base class, BasicMathGate, with the corresponding function, so it can be emulated efficiently.
