Initial reactions to the album were mixed on social media.^[8] Writing for Milliyet, Mehmet Tez noticed Tarkan's attempt to live up to his old image and lamented his desire to "recreate his image from the 1990s and the first half of the 2000s. ... Today, with Kuantum 51, he repeats what he had attempted in a series of albums, starting with Metamorfoz (2011). He's competing with the megastar Tarkan of 20 years ago. If this is the opponent you are facing, it is impossible to win."^[9] Writing for Hürriyet, Sinem Vural also noted that "Tarkan is always expected to deliver the same '90s hits. But he's delivering 'what pop music should be like in 2024'". She added that the album could be catchy and "if you listen to it with your expectations cleared, you will understand Tarkan's new age, his place in his career, his own tastes, and you will memorize the lyrics in a short time".^[3] Writing for Sabah, Yüksel Aytuğ found "Müteşekkir" as "the song with the best lyrics on the album" and "Darmaduman" as the only memorable piece. He concluded: "In short, Kuantum 51 made me ask, 'Where are the old Tarkan albums that were all hits?'".^[10]
