qat.lang.AQASM.arithmetic.mult_const_mod

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

Generates a QRoutine performing the following operation:

\[| a \rangle | b \rangle \mapsto |a \rangle | b + a \times \textrm{constant} \mod \textrm{modulus} \rangle\]

Parameters:

• reg_size (int) – the register size

• acc_size (int) – the accumulator size

• constant (int) – the constant to add

• modulus (int) – the modulus value

Warning

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

This routine calls:

• qat.lang.AQASM.arithmetic.add_const_mod()

  with arguments (acc_size, _, _)
