QSharp and Quantum Console

This is the home page of QSharp, a quantum computing and information simulation project written in C# running on the Microsoft.NET plaform. QSharp includes the Quantum Console, a console application used to execute commands against a register of simulated quantum bits.

This project is designed to assist programmers in understand quantum information fundamentals, and how operations performed in a quantum computer may function.

You may prepare the register with your own amplitude values.

Register initialised with 3 qubits, 8 basis states

(A|0› + B|1›) (x) (C|0› + D|1›) (x) (E|0› + F|1›)

ACE 0.555|000› + ACF 0.396|001› + ADE 0.238|010› + ADF 0.170|011› + BCE 0.502|100› + BCF 0.357|101› + BDE 0.215|110› + BDF 0.153|111›

Syntax

Valid commands follow the following form:

{GateName}({QubitNumber});

For example, the following command performs a NOT operation on the first qubit (A|0› + B|1›):

X(0);

*Note that qubit indicies are 0 based, not 1 based.

Multiple commands may be specified by delimiting instructions with a semicolon:

X(0); X(1);

Multiple commands may appear also on seperate lines, specified by delimiting instructions with a semicolon:

X(0);
X(1);

Refer to the following documentation for in-depth explanations of each command, how to execute them, and what is happening 'under the hood'.
