    "abstract": "Future wired and wireless communication systems will employ pure or combined\nCode Division Multiple Access (CDMA) technique, such as in the European 3G\nmobile UMTS or Power Line Telecommunication system, but also several 4G\nproposal includes e.g. multi carrier (MC) CDMA. Former examinations carried out\nthe drawbacks of single user detectors (SUD), which are widely employed in\nnarrowband IS-95 CDMA systems, and forced to develop suitable multiuser\ndetection schemes to increase the efficiency against interference. However, at\nthis moment there are only suboptimal solutions available because of the rather\nhigh complexity of optimal detectors. One of the possible receiver technologies\ncan be the quantum assisted computing devices which allows high level\nparallelism in computation. The first commercial devices are estimated for the\nnext years, which meets the advert of 3G and 4G systems. In this paper we\nanalyze the error probability and give tight bounds in a static and dynamically\nchanging environment for a novel quantum computation based Quantum Multiuser\ndetection (QMUD) algorithm, employing quantum counting algorithm, which\nprovides optimal solution.",
