我有一个新的Microsoft Quantum Development Kit的简单Q#示例的编译错误:
namespace Quantum.Bell
{
open Microsoft.Quantum.Primitive;
open Microsoft.Quantum.Canon;
operation Set (desired: Result, q1: Qubit) : Unit
{
let current = M(q1);
if (desired != current)
{
X(q1);
}
}
operation BellTest (count : Int, initial: Result) : (Int, Int)
{
mutable numOnes = 0;
using (qubit = Qubit())
{
for (test in 1..count)
{
Set (initial, qubit);
let res = M (qubit);
// Count the number of ones we saw:
if (res == One)
{
set numOnes = numOnes + 1;
}
}
Set(Zero, qubit);
}
// Return number of times we saw a |0> and number of times we saw a |1>
return (count-numOnes, numOnes);
}
}
C#Quantum Simulator代码看起来像
using System;
using Microsoft.Quantum.Simulation.Core;
using Microsoft.Quantum.Simulation.Simulators;
namespace Bell
{
class Driver
{
static void Main(string[] args)
{
using (var qsim = new QuantumSimulator())
{
// Try initial values
Result[] initials = new Result[] { Result.Zero, Result.One };
foreach (Result initial in initials)
{
var res = BellTest.Run(qsim, 1000, initial).Result;
var (numZeros, numOnes) = res;
System.Console.WriteLine(
$"Init:{initial,-4} 0s={numZeros,-4} 1s={numOnes,-4}");
}
}
System.Console.WriteLine("Press any key to continue...");
System.Console.ReadKey();
}
}
}
用
dotnet run
编译时,我得到ip-192-168-1-103:Bell loretoparisi$ dotnet run
Driver.cs(18,31): error CS0103: The name 'BellTest' does not exist in the current context [/Users/loretoparisi/Documents/Projects/AI/quantum/Bell/Bell.csproj]

The build failed. Please fix the build errors and run again.

最佳答案
名称空间不匹配:Q#代码中使用的命名空间为Quantum.Bell
,而C#代码中使用的命名空间仅为Bell
-您需要修复文件以使用相同的命名空间,或添加using Quantum.Bell;
到C#代码。
