Module circuits

Commonly used quantum circuits.

You can easily use basic operations such as addition and subtraction and major quantum circuits such as quantum Fourier transform.

Functions

add_const

A quantum circuit that directly overwrites the input qubit with the result of adding the value represented by the qubit and a constant.

add_const_2_power

|0⟩|b⟩ → |overflow⟩|b + 2^m⟩

cmm_const

A circuit that multiplies input qubits by a constant and stores the result of modular operation using the constant in the input qubit.

full_adder_bit

|a⟩|b⟩|C⟩|0⟩ → |a⟩|a+b+c⟩|C⟩|C_out⟩

full_adder_nbits

|a⟩|b⟩|0⟩ → |a⟩|a+b⟩|0⟩

half_adder_bit

Circuit that performs half addition on qubit

inv_qft

Circuit that performs inverse quantum Fourier transform

me_const

A circuit that outputs the result of modular operation with n_const after raising a_const to the power of the input qubit.

mod_add

A quantum circuit that stores the result of addition and modular operation in one input bit.

mod_add_const

A quantum circuit that adds constants and multiplies modular operations using constants, and stores the result in one input bit.

overflow_qadd_const

Add const_a to b and store the result in b. Store overflow results

overflow_qadd_const_2_power

Add the input 2 to the power of m to b and store the result in b. Store overflow results

overflow_qsub_const

Substract const_a to b and store the result in b. Store overflow results

qft

Circuit that performs quantum Fourier transform

sub_const

|0⟩|b⟩|0⟩ → |sign⟩|b + a⟩|0⟩

substract_nbits

swap

Swap Q-bit between index of a_in and b_in

wrapping_qadd_const

Wrapping add const_a to b and store the result in b.

wrapping_qadd_const_2_power

Wrapping add the input 2 to the power of m to b and store the result in b. |b⟩ → |b + 2^m⟩

wrapping_qsub_const

Wrapping substract const_a to b and store the result in b.
