Quantum Walk Algorithms are related to random walks. A random walk is a probability distribution over some states. Quantum walk is a quantum superposition over states.
Algorithms based on quantum walks are listed below.
In C#, variadic templates can be classes with repeated methods or use collection initializers and compile them into series of calls. Q# and C# are used to write quantum programs. Variadic templates help writing C# Drivers.
The code snippet shows Add Call with its own generic parameters and type inference.
using System;
using System.Collections.Generic;
using System.IO;
using System.Net;
using Microsoft.Quantum.Simulation.Core;
using Microsoft.Quantum.Simulation.Simulators;
namespace Hello
{
class Driver
{
static void Main(string[] args)
{
Container listContainer = new Container() {
() => new List<byte>()
};
Container memoryContainer = new Container() {
() => new MemoryStream()
};
Container credentialContainer = new Container() {
() => new CredentialCache()
};
Console.WriteLine(listContainer + "Type " + listContainer.GetType());
Console.WriteLine(memoryContainer + "Type " + memoryContainer.GetType());
Console.WriteLine(credentialContainer + "Type " + credentialContainer.GetType());
}
}
class Container : System.Collections.IEnumerable
{
public void Add<T>(Func<T> func)
{
}
System.Collections.IEnumerator System.Collections.IEnumerable.GetEnumerator()
{
throw new NotSupportedException();
}
}
}Run the following commands to execute the project in Visual Studio Code:
^F5 In the terminal, you can execute the build by running the command below.
dotnet run

Parameterized types are specified in generic classes. Generics in C# is powerful feature which defines the type-safe data structures. They are similar to templates in C++. The parameters can be typed by using generics in methods and classes. The framing of data type is deferred till the class or the method is declared and instantiated & executed by client code. They reduce the overhead of following operations :
The code snippet below shows ParameterizedTypes Class which takes a generic type parameter ’T’.
public class ParameterizedTypes<T>
{
private T data;
public T value
{
get
{
return this.data;
}
set
{
this.data = value;
}
}
}The Driver class has Main method, in which ParameterizedTypes Class is instantiated as string and float. The constructor accepts the required type for ParameterizedTypes class.
using System;
using Microsoft.Quantum.Simulation.Core;
using Microsoft.Quantum.Simulation.Simulators;
namespace Hello
{
class Driver
{
static void Main(string[] args)
{
ParameterizedTypes<string> name = new ParameterizedTypes<string>();
name.value = "Parameterized Types";
ParameterizedTypes<float> version = new ParameterizedTypes<float>();
version.value = 7.0F;
Console.WriteLine(name.value);
Console.WriteLine(version.value);
}
}

Q# is a programming language for quantum computing. Q# draws on inspiration from F# as a functional language, C# for syntax, and draws some ideas from Python.
A Q# operation is a callable routine, which contains Q# code to carry out a quantum operation. An operation is the basic unit of quantum execution in Q#. It returns a single value as output, specified after a colon, and may be a tuple.
A Q# Function is classical subroutine used within a Quantum algorithm and can only contain classical code. A function will take a single value as input and returns a single value as output.
namespace Quantum.HelloWorld
{
open Microsoft.Quantum.Canon;
open Microsoft.Quantum.Primitive;
operation SayHello () : Unit {
Message("Hello World!");
}
}
