qat.lang.AQASM.arithmetic.mult_const

qat.lang.AQASM.arithmetic.mult_const(reg_size: int, acc_size: int, constant: int)

Generates a QRoutine performing a multiplication between a register of size reg_size and a constant, accumulating the result in a register of size acc_size . By default, acc_size is chosen equal to reg_size .

Parameters

• reg_size (int) – the registers size

• acc_size (int) – the accumulator size

• constant (int) – the constant to add

Warning

Some additional qubits might be allocated by sub-routines inside this routine.

This routine calls:

• Any addition by a constant (E.g: qat.lang.AQASM.qftarith.add_const()

  or qat.lang.AQASM.classarith.add_const()) with arguments (acc_size )
