+class AntiCommutator(Expr):
+    """The standard anticommutator, in an unevaluated state.
+
+    Explanation
+    ===========
+
+    Evaluating an anticommutator is defined [1]_ as: ``{A, B} = A*B + B*A``.
+    This class returns the anticommutator in an unevaluated form.  To evaluate
+    the anticommutator, use the ``.doit()`` method.
+
+    Canonical ordering of an anticommutator is ``{A, B}`` for ``A < B``. The
+    arguments of the anticommutator are put into canonical order using
+    ``__cmp__``. If ``B < A``, then ``{A, B}`` is returned as ``{B, A}``.
+
+    Parameters
+    ==========
+
+    A : Expr
+        The first argument of the anticommutator {A,B}.
+    B : Expr
+        The second argument of the anticommutator {A,B}.
+
+    Examples
+    ========
+
+    >>> from sympy import symbols
+    >>> from sympy.physics.quantum import AntiCommutator
+    >>> from sympy.physics.quantum import Operator, Dagger
+    >>> x, y = symbols('x,y')
+    >>> A = Operator('A')
+    >>> B = Operator('B')
+
+    Create an anticommutator and use ``doit()`` to multiply them out.
+
+    >>> ac = AntiCommutator(A,B); ac
+    {A,B}
+    >>> ac.doit()
+    A*B + B*A
+
+    The commutator orders it arguments in canonical order:
+
+    >>> ac = AntiCommutator(B,A); ac
+    {A,B}
+
+    Commutative constants are factored out:
+
+    >>> AntiCommutator(3*x*A,x*y*B)
+    3*x**2*y*{A,B}
+
+    Adjoint operations applied to the anticommutator are properly applied to
+    the arguments:
+
+    >>> Dagger(AntiCommutator(A,B))
+    {Dagger(A),Dagger(B)}
