Private　information　retrieval　implies　oblivious　transfer　in　classical　cryptography.　Following　this　clue,　we　present　a　novel　quantum　one-out-of-two　OT　protocol　based　on　a　practical　quantum　symmetrically　private　information　retrieval　protocol　Jakobi　et　al.　(Phys.　Rev.　A　83(2),　022301　2011),　with　changes　only　in　the　classical　postprocessing　of　the　key.　While　unconditionally　secure　oblivious　transfer　is　known　to　be　impossible,　we　argue　that　an　interesting　degree　of　security　can　be　achieved　by　means　of　quantum　physical　principles　instead　of　unproven　security　assumptions　in　order　to　protect　both　the　sender　and　the　receiver.　The　proposed　OT　protocol　is　loss　tolerant,　practical　and　robust　against　quantum　memory　attack.
