Quantum Computation Language

Quantum Computation Language (QCL) is one of the first implemented <a href="/facts/Quantum_programming/oDpNfGSA">quantum programming</a> <a href="/facts/Programming_languages/cWTYbgWa">languages</a>. The most important feature of QCL is the support for user-defined operators and functions. Its <a href="/facts/Syntax/6PxSV98p">syntax</a> resembles the syntax of the <a href="/facts/C_programming_language/Ky2No763">C programming language</a> and its classical <a href="/facts/Data_type/fcx5hgVL">data types</a> are similar to primitive data types in C. One can combine classical code and quantum code in the same program.
The language was created before there were multi-qubit quantum computers and the only implementation of QCL uses an interpreter with a built-in classically simulated quantum computer.
QCL was created to explore programming concepts for quantum computers.
The QCL library provides standard quantum operators used in quantum algorithms such as:

<ul><li>Controlled-not with many target qubits,</li>
<li><a href="/facts/Hadamard_operation/EFV5sPCU">Hadamard operation</a> on many qubits,</li>
<li>Phase and controlled phase.</li>
<li>Quantum algorithms for addition, multiplication and exponentiation with binary constants (all modulus n)</li>
<li>The <a href="/facts/Quantum_Fourier_transform/pT71oCV7">quantum fourier transform</a></li></ul>
