How to add a vector image .eps file from Illustrator to Photoshop CS6 without extreme

Hello

I have a vector image in the form of an .eps file and I want to transfer it to Photoshop. I need to re-size the image to a much smaller 150x150 pixel frame size JPEG image and every strategy I have used has resulted in extreme loss of quality and pixelization. Is there a way to transfer my vector from Illustrator to Photoshop CS6, or at least properly resize the image through Illustrator so that I can import a high quality version at those 150x150 dimensions?

Thanks!

greatly simplify your image. 150x150 means little detail or edge definition for complex art. Your gorgeous subtle logo with blends and transparency and hairlines fall apart when shrunk so far. Look at the avatars on this site, they are 100x100. It is hard to get the Mona Lisa on a postage stamp and still see her smile.
