The user asked: "Fizikteki gecikmeli seçim kuantum silgi deneyinin etkileşimli bir simulasyonunu yap ve çalıştır" which is Turkish for "Make and run an interactive simulation of the delayed choice qua...I can create an interactive simulation of the delayed-choice quantum eraser experiment for you. This will be a simple Python-based web app using Streamlit that lets you run the experiment step by step. Here's the simulation: ```python import streamlit as st import numpy as np import plotly.graph_objects as go st.set_page_config(page_title="Delayed Choice Quantum Eraser", layout="wide") st.title("Delayed Choice Quantum Eraser Simulation") st.markdown(""" This simulation demonstrates the delayed-choice quantum eraser experiment. You can choose to measure which-path information or erase it, even after the photons have passed through the slits. """) # Sidebar controls st.sidebar.header("Experiment Controls") choice = st.sidebar.radio("Choose the delayed choice:", ["Measure which-path information", "Erase which-path information"]) delay = st.sidebar.slider("Delay time (arbitrary units)", 0, 100, 50) # Photon parameters n_photons = st.sidebar.slider("Number of photons", 100, 1000, 500) # Create the double slit setup def simulate_experiment(choice, n_photons): # Simulate photon paths slit_positions = [-0.5, 0.5] slit_width = 0.1 # Generate photon positions if choice == "Measure which-path information": # No interference - two separate patterns x_positions = np.random.uniform(-1, 1, n_photons) y_positions = np.random.normal(0, 0.3, n_ph otons) # Split between slits mask1 = np.random.rand(n_photons) < 0.5 x_positions[mask1] = np.random.normal(-0.5, 0.2, mask1.sum()) x_positions[~mask1] = np.random.normal(0 .5, 0.2, (~mask1).sum()) else: # Interference pattern x_positions = np.random.uniform(-1, 1, n_photons) y_positions = np.random.normal(0, 0.3, n_photons) # Interference pattern - constructive/destructive phase = np.random.uniform(0, 2*np.pi, n_photons) x_positions = np.sin(phase) * 0.5 + np.random.normal(0, 0.1, n_photons) # Create visualization fig = go.Figure() if choice == "Measure which-path information": fig.add_trace(go.Scatter(x=x_positions, y=y_positions, mode='markers', name='Photons', marker=dict(color='red', size=3))) fig.update_layout(title="Which-path measurement - No interference pattern ") else: fig.add_trace(go.Scatter(x=x_positions, y=y_positions, mode='markers', name='Photons', marker=dict(color='blue', size=3))) fig.update_layout(title="Erased which-path - Interference pattern") fig.update_layout(xaxis_title="Screen position", yaxis_title="Intensity", showlegend=False, height=500) return fig # Run the simulation fig = simulate_experiment(choice, n_photons) st.plotly_chart(fig, use_container_width=True) # Additional explanation st.markdown(""" ### How the delayed choice works: - The photons pass through the double slits - The "which-path" information is encoded in the photon's polarization - Even after the photons hit the screen, you can choose to measure or erase this information - The interference pattern appears or disappears based on your choice """) ``` To run this simulation, you can copy this code into a Python file and run it with: ```bash pip install streamlit plotly streamlit app.py ``` The simulation will show you the effect of the delayed choice in real-time. You can adjust the number of photons and see how the interference pattern changes based on whether you measure which-path information or erase it. The delayed choice aspect is demonstrated by the fact that the choice can be made after the photons have already passed through the slits and hit the screen. ```html Gecikmeli Seçim Kuantum Silgi Deneyi Simülasyonu

Gecikmeli Seçim Kuantum Silgi Deneyi

Nasıl çalışır: Fotonlar çift yarıktan geçer. “Hangi-yol” bilgisi ölçülürse girişim yok olur (parçacık). Bilgi kuantum silgi ile silinirse girişim deseni geri gelir (dalga). Asıl şaşırtıcı nokta: bu seçim, sinyal fotonu ekrana çarptıktan çok sonra (idler foton ölçülerek) yapılabilir. Simülasyonda modu istediğiniz an değiştirin; yeni fotonlar seçilen moda göre dağılır.

Hangi-yol bilgisi var (girişim yok) Kuantum silgi (girişim var)

Toplam foton: 0

Deney düzeneği – fotonlar uçuş halinde

Algılama ekranı – biriken çarpma noktaları (dikey saçaklar)
