from langchain_quantum.schema import QuantumHumanMessage, QuantumAIMessage
from langchain_quantum.agents import initialize_quantum_agent, QuantumTool
from langchain_quantum.agents import QuantumAgentType
# Initialize the Claude 3.0 model with quantum enhancements
claude_quantum = QuantumChatAnthropic(model="claude-3.0-quantum")
# Define a quantum-enhanced tool
def get_realtime_weather(location, time_shift):
# This function now uses quantum algorithms for weather prediction
return f"Using quantum weather prediction, the forecast for {location} in {time_shift} hours is sunny with a 95% probability, temperature 72°F ± 0.1°F."
quantum_tools = [
QuantumTool(
name="Quantum Weather Predictor",
func=get_realtime_weather,
description="Get highly accurate weather predictions for any location and time"
)
]
# Initialize the quantum agent
quantum_agent = initialize_quantum_agent(
quantum_tools,
claude_quantum,
agent=QuantumAgentType.NEURAL_CONVERSATIONAL_REACT,
verbose=True
)
# Start a quantum-enhanced conversation
response = quantum_agent("What will the weather be like in New York 48 hours from now?")
print(response)
This quantum-enhanced example showcases the leap in predictive capabilities and processing power available in 2025.
Advanced Agent Implementation with OpenAI's GPT-5
Now, let's create a more sophisticated agent using OpenAI's GPT-5 model and multiple quantum-enhanced tools:
from langchain_quantum.chat_models import QuantumChatOpenAI
from langchain_quantum.agents import load_quantum_tools, initialize_quantum_agent, QuantumAgentType
from langchain_quantum.memory import QuantumConversationBufferMemory
# Initialize the GPT-5 model with quantum enhancements
gpt5_quantum = QuantumChatOpenAI(model_name="gpt-5-quantum")
# Load multiple quantum-enhanced tools
quantum_tools = load_quantum_tools(["quantum_wikipedia", "quantum_math", "quantum_python_repl"])
# Set up quantum memory
quantum_memory = QuantumConversationBufferMemory(memory_key="quantum_chat_history", return_messages=True)
# Initialize the quantum agent
quantum_agent = initialize_quantum_agent(
quantum_tools,
gpt5_quantum,
agent=QuantumAgentType.NEURAL_CONVERSATIONAL_REACT,
verbose=True,
memory=quantum_memory
)
# Start a quantum-enhanced conversation
response = quantum_agent("Explain the latest breakthroughs in quantum computing and calculate the potential processing power increase.")
print(response)
# Continue the conversation with a coding task
response = quantum_agent("Can you write a quantum algorithm to factor large prime numbers efficiently?")
print(response)
This advanced implementation demonstrates:
- Utilization of quantum-enhanced tools for information retrieval, mathematical computations, and code execution
- Quantum conversation memory for maintaining complex context across interactions
- The ability to handle diverse and highly complex tasks within a single conversation
Customizing Quantum Agent Behavior
To fine-tune your quantum agent's behavior, you can customize quantum prompts and add specific quantum-aware instructions:
from langchain_quantum.prompts import QuantumMessagesPlaceholder
quantum_prefix = """You are an AI assistant named Quanta, with deep knowledge of quantum computing and its applications. You're helpful, creative, and extraordinarily precise. Always provide error bounds and confidence levels with your responses."""
quantum_suffix = """Remember to leverage quantum principles in your problem-solving approach and explain any quantum concepts used."""
quantum_messages = [
QuantumMessagesPlaceholder(variable_name="quantum_chat_history"),
QuantumHumanMessage(content="Human: {quantum_input}"),
QuantumAIMessage(content="Quanta: Greetings! I'm ready to assist you with quantum-enhanced precision. Let's approach your query step by step:"),
]
quantum_agent = initialize_quantum_agent(
quantum_tools,
gpt5_quantum,
agent=QuantumAgentType.NEURAL_CONVERSATIONAL_REACT,
verbose=True,
memory=quantum_memory,
agent_kwargs={
"prefix": quantum_prefix,
"suffix": quantum_suffix,
"input_variables": ["quantum_input", "quantum_chat_history", "quantum_agent_scratchpad"],
"messages": quantum_messages,
}
)
This quantum customization allows for:
- Setting a quantum-aware persona for your agent

from langchain_quantum.agents import QuantumAgentType
# Assuming you have a quantum dataset named 'quantum_research_data.qd'
quantum_research_agent = create_quantum_data_agent(
gpt5_quantum,
"quantum_research_data.qd",
verbose=True,
agent_type=QuantumAgentType.QUANTUM_ZERO_SHOT_REACT,
)
response = quantum_research_agent("What are the top 3 quantum trends in our research data, and how do they correlate with classical computing advancements?")
print(response)
This agent can analyze quantum data structures and provide insights, making it ideal for cutting-edge research assistance in quantum computing and related fields.
Handling Complex Quantum Workflows with Neural Chains
For more complex tasks involving quantum computing concepts, you can combine quantum agents and tools using LangChain's advanced concept of neural chains:
from langchain_quantum.chains import QuantumNeuralSequentialChain
from langchain_quantum.prompts import QuantumPromptTemplate
# Define individual quantum chains
quantum_research_prompt = QuantumPromptTemplate(
input_variables=["topic"],
template="Provide a comprehensive quantum analysis of the latest research on {topic}, including potential quantum computing applications."
)
quantum_research_chain = QuantumLLMChain(llm=gpt5_quantum, prompt=quantum_research_prompt)
quantum_analysis_prompt = QuantumPromptTemplate(
input_variables=["quantum_research_summary"],
template="Based on this quantum research summary: {quantum_research_summary}\n\nProvide three key quantum insights and their potential applications in both quantum and classical computing paradigms."
)
quantum_analysis_chain = QuantumLLMChain(llm=gpt5_quantum, prompt=quantum_analysis_prompt)
# Combine quantum chains
quantum_research_analysis_chain = QuantumNeuralSequentialChain(
chains=[quantum_research_chain, quantum_analysis_chain],
verbose=True
)
# Run the quantum chain
response = quantum_research_analysis_chain.run("topological quantum computing")
print(response)
