Dave Gorski has an article at Science-Based Medicine about the use and abuse of quantum mechanics to justify pretty much any form of flim flam and quackery anyone wants to sell to the ignorant and the credulous. And as he points out, Deepak Chopra may be the worst at this:
Among the favorite real science term that quacks love to appropriate is “quantum.” I blame Deepak Chopra. Although I highly doubt he was the first promoter of alternative medicine and various New Age thought to use and abuse the term “quantum” as a seemingly scientific justification of what in reality is nothing more than ancient mystical thinking gussied up with a quantum overcoat to hide its lack of science, Chopra has arguably done the most to popularize the term among the science-challenged set. In Chopra’s world, the word “quantum” functions like a magical talisman that explains ™everything because in the quantum world anything can happen. Actually, I should clarify. While it’s true that many bizarre and wondrous things can be explained through quantum theory (such as quantum entanglement), it is not, as Chopra and his many imitators would have you believe, a “get out of jail free” card for any magical thinking you can imagine, and quantum effects do not work the way people like Chopra (say, Lionel Milgrom, who seems to think that homeopathy works through quantum entanglement between practitioner, remedy, and patient) would like you to think.
He also highlights a new and hilarious bit of lunacy from QuantumMANtm, which bills itself as “the world’s first downloadable medicine.” All you have to do is sign up, and pay your money of course, and medicinal “data” will “transfer from a remote quantum computer to your brain’s neural network for the benefits desired.” And did I mention that this is “extraterrestrial technology” that was “provided by an advanced civilization” and it will turn your cell phone into a “personal medical tricorder to instantly diagnose and treat your pet”? This is weapons-grade hooey.
