In Harry Potter and the Chamber of Secrets, Tom Riddle says the following to Harry:
‘If I say it myself, Harry, I’ve always been able to charm the people I needed. So Ginny poured out her soul to me, and her soul happened to be exactly what I wanted. I grew stronger and stronger on a diet of her deepest fears, her darkest secrets. I grew powerful, far more powerful than little Miss Weasley. Powerful enough to start feeding Miss Weasley a few of my secrets, to start pouring a little of my soul back into her ...’
Chamber of Secrets - page 228 - Bloomsbury - chapter 17, The Heir of Slytherin
So, Voldemort put parts of his soul into Ginny.
J.K. Rowling describes Professor Quirrell's possession by (the barely alive and very fragmented) Voldemort as a "partial Horcrux".
While Quirrell did not lose his soul, he became completely subjugated by Voldemort, who caused a frightful mutation of Quirrell's body: now Voldemort looked out of the back of Quirrell's head and directed his movements, even forcing him to attempt murder. Quirrell tried to put up feeble resistance on occasion, but Voldemort was far too strong for him.
Quirrell is, in effect, turned into a temporary Horcrux by Voldemort. He is greatly depleted by the physical strain of fighting the far stronger, evil soul inside him. Quirrell’s body manifests burns and blisters during his fight with Harry due to the protective power Harry's mother left in his skin when she died for him. When the body Voldemort and Quirrell are sharing is horribly burned by contact with Harry, the former flees just in time to save himself, leaving the damaged and enfeebled Quirrell to collapse and die.
Professor Quirrell - POTTERMORE - J.K. Rowling
Both Quirrell and Ginny did not ultimately lose their souls to Voldemort. Both were subjugated by Voldemort (both tried to fight back) and both were greatly physically depleted by their contact with him. Both housed Voldemort in their very beings, their souls. Neither had the Horcrux spell performed on them, nor were there murders associated with either Ginny or Quirrell (which is required to make a Horcrux).
Is Ginny Weasley considered a "temporary Horcrux" in the way that Professor Quirrell is?
