Naomi Owen, Joanna Parker and Na Liu will compete, as English national champion Kelly Sibley is ruled out because a hip injury.
As a final fall-back, if no player qualifies, Great Britain is still entitled to six player spots at the London 2012 Games as host nation.
‘A couple of weeks ago, I did not really know if they were going to send anybody. I am delighted that I am going – I think everybody wants to go without using a host nation place.
‘I think if I am in good shape and playing well then it is possible to qualify, but it is going to be difficult with only two places available.’
Two spots are up for grabs in each of the men’s and women’s competitions at the final world Olympic Qualification Tournament in Qatar.
