For Mitchel
Special thanks to Anne Lesley Groell for her brilliant editing and uncanny ear for what I meant to say; to Charles H. Bennett, John A. Smolin, and Mavis Donkor of the Quantum Information Group at IBM’s Watson Labs for brainstorming, technical advice, and quantum teleportation jokes; to Ann Chamberlin and M. Shayne Bell for kindness above and beyond the call of duty; to Scott Anderson, Julia Junkala, Jim McLaughlin, Susan Mayse, Tony Pustovrh, and Kirsten Underwood for being the best readers any writer could ask for; to Judith Tarr for sensible advice and extravagant encouragement; to John Dorfman for being there at the beginning… and of course to the fabulous Jimmy Vines, who made it all happen.
