Exercise - Use the Copilot to run a quantum program

Completed

In this unit, you'll learn how to use Copilot in Azure Quantum to explore quantum computing and quantum programming. Copilot is an AI-powered tool that can generate Q# code from your prompts and engage in conversations about quantum computing. You can also run your code and ask Copilot to explain quantum computing concepts.

To start exploring Copilot and coding in Azure Quantum, use one of the samples from the Quantum Samples dropdown.

Run a quantum program

1. Navigate to Code in Azure Quantum.

2. Select Quantum Samples, and then select Random Number Generator. The following code is copied to the code window.

   /// # Sample
   /// Quantum Random Number Generator
   ///
   /// # Description
   /// This program implements a quantum ranndom number generator by setting qubits
   /// in superposition and then using the measurement results as random bits.
   import Microsoft.Quantum.Measurement;
   import Microsoft.Quantum.Intrinsic;
   
       operation Main() : Result[] {
           // Generate 5-bit random number.
           let nBits = 5;
           return GenerateNRandomBits(nBits);
       }
   
       /// # Summary
       /// Generates N random bits.
       operation GenerateNRandomBits(nBits : Int) : Result[] {
           // Allocate N qubits.
           use register = Qubit[nBits];
   
           // Set the qubits into superposition of 0 and 1 using the Hadamard
           // operation `H`.
           for qubit in register {
               H(qubit);
           }
   
           // At this point each has 50% chance of being measured in the |0〉 state
           // and 50% chance of being measured in the |1〉 state.
           // Measure each qubit and reset them all so they can be safely
           // deallocated.
           let results = MeasureEachZ(register);
           ResetAll(register);
           return results;
       }
   

3. Select In-Memory Simulator.

4. Select Run.

   • The results are displayed in the Results field, and a histogram of the results is displayed below the code window.
   • You can move the slider for Select number of shots to specify how many times the program is run.
   • The Shots field displays the result for each shot.

To run your program again using a different simulator:

1. Select the In-Memory Simulator dropdown and select Quantinuum H-Series Emulator.

2. Select the number of shots (currently limited to 20) and select Run.

   • The job status is displayed at the top of the code window.
   • A histogram of the results is displayed below the code window. Results for each shot aren't currently available with the Quantinuum H-Series Emulator.

Ask Copilot

You can prompt Copilot in Azure Quantum for almost anything quantum related. For example, ask Copilot the following questions and see what happens:

• "Explain the MResetZ operation"
• "Write Q# code that entangles two qubits"
• "Explain quantum interference"
• "What is the difference between a qubit and a classical bit?"
