On the first day of the Games, Kvassov placed twenty-first for the Kazakhstan team in the 4×100 m freestyle relay. Teaming with Sergey Borisenko, Pavel Sidorov, and Igor Sitnikov in heat three, Kvassov swam a second leg and recorded a split of 52.25, but the Kazakhs settled only for last place in a final time of 3:28.90. The following day, in the 200 m freestyle, Kvassov placed forty-eighth on the morning prelims. Swimming in heat two, he touched out Cyprus' Alexandros Aresti for a seventh seed by almost a full body length in 1:55.72.

Kvassov made his official debut for Kyrgyzstan at the 1996 Summer Olympics in Atlanta. He failed to reach the top 16 final in the 400 m freestyle, finishing twenty-sixth in a time of 4:00.69. A member of the Kyrgyzstan team, he also placed eighteenth in the 4×100 m freestyle relay (3:30.62), and seventeenth in the 4×200 m freestyle relay (8:00.00).
