Learn the key principles and mathematical foundations of quantum computing. Build your first quantum circuit with interactive code demonstrations.
The fundamental unit of quantum information, existing in superposition of |0> and |1> states.
Enables quantum states that are combinations of classical basis states (|0> + |1>).
Links qubits so their states depend on each other (Bell states and EPR pairs).
Unitary operations (Hadamard, CNOT) that manipulate qubit states.
// Create superposition
operation CreateQubitState() : Unit {
use q = Qubit();
H(q); // Apply Hadamard gate
X(q); // Apply Pauli-X gate
M(q); // Measurement
Set(Qubit(), PauliOne, 0);
}
This example demonstrates a quantum circuit that prepares a qubit in a superposition state using the Hadamard gate and then applies a bit-flip operation.
dotnet new -i Microsoft.Quantum.ProjectTemplates
Set up Microsoft's quantum development kit for local quantum circuit simulation and visualization with full .NET integration.
dotnet new console -o my-quantum-project

Edit Operations.qs with this basic Bell state circuit:
namespace Bell {
open Microsoft.Quantum.Intrinsic;
operation CreateBellState() : Unit {
use (q0, q1) = (Qubit(), Qubit());
H(q0); // Superposition on first qubit
CNOT(q0, q1); // Entangle with second qubit
MResetZ(q0, q1); // Measurement
}
}
dotnet run --project my-quantum-project
The QDK simulator will display results with probability distributions and quantum state visualizations.
