    "abstract": "3G and 4G mobile are based on CDMA technology. In order to increase the\neffectiveness of CDMA receivers large amount of effort is invested to develop\nsuitable multi-user detector techniques. However, at this moment there are only\nsuboptimal solutions available because of the rather high complexity of optimal\ndetectors. One of the possible receiver technologies can be the quantum\nassisted computing devices which allows high level parallelism in computation.\nThe first commercial devices are estimated by 2004, which meets the advert of\n3G and 4G systems. In this paper we introduce a novel quantum computation based\nQuantum Multi-user detection (QMUD) algorithm, employing simple Positive\nOperation Valued Measurement (POVM), which provides optimal solution. The\nproposed algorithm is robust to any kind of noise.",
