dynacir

Description

Dynacir is a transpilation plugin for Qiskit that optimizes dynamic quantum circuits.

Features

• Feature 1 (current): Merges sequential resets on a given qubit into a single reset.
• Feature 2 (upcoming): Merge sequences of reset-first single-qubit gate-...-reset-final single-qubit gate into just reset-final single-qubit gate
• Feature 3 (upcoming): Compile inefficient classical logic to minimize memory load

Installation

To install dynacir, run the following command in your terminal:

pip install git+https://github.com/derek-wang-ibm/dynacir.git

Usage

First, create a QuantumCircuit.`

from qiskit import QuantumCircuit, transpile

qc = QuantumCircuit(2)
qc.reset(0)
qc.x(0)
qc.cx(0, 1)
qc.reset(0)
qc.reset(0)
qc.h(0)
qc.draw(output='mpl', style='iqp')

Then, apply a PassManager generated using the dynacir plugin.

from qiskit.transpiler.preset_passmanagers import generate_preset_pass_manager
from qiskit_ibm_runtime import QiskitRuntimeService

pm = generate_preset_pass_manager(optimization_level=3, optimization_method="dynacir"

qc_dynacir = pm.run(qc)
qc_dynacir.draw(output='mpl', style='iqc')
)
