I think the querybuilder looks alright. Your problem is likely in the data structure.

The way you normally approach this is by setting up a property per relation. For your Users class it'd make sense to have an information or userInformation one for example.

Perhaps something like this helps?

class User
{
    /**
     * @ORM\Id
     */
    protected $id;

    /**
     * @ORM\OneToOne(targetEntity="UserInformation")
     */
    protected $information;
}

class UserInformation
{
    /**
     * @ORM\Id
     */
    protected $id;

    /**
     * @ORM\OneToOne(targetEntity="User", inversedBy="information")
     * @ORM\JoinColumn(name="user_id", referencedColumnName="id")
     */
    protected $user;
}
