Alternative medicine quackery is spreading throughout medicine, but is especially common in psychiatry:
Complexity theory, quantum mechanics, and quantum field theory are conceptual frameworks that have been largely overlooked by Western medicine as potentially useful explanatory models of illness and healing. These nonclassical paradigms may eventually lead to models or research methods that will clarify the nature of putative informational or energetic phenomena related to health, illness, and healing. Phenomena regarded as legitimate subjects of inquiry in nonorthodox paradigms that have been largely overlooked by Western biomedical research include the role of intention in healing and the putative beneficial effects of “subtle energy” on health.
Quantum brain dynamics is a nonclassical model that uses quantum field theory to explain subtle dynamic characteristics of brain functioning, including postulated influences of nonclassical forms of energy and information on the brain. It has been suggested that healing intention operates through nonlocal energetic interactions between the consciousness of the medical practitioner and the physical body or consciousness of the patient. Conventionally trained physicians generally regard reports of beneficial outcomes following “energy” treatments as examples of the placebo effect because contemporary Western science is not able to substantiate the role of postulated forms of nonclassical energy when these modalities are employed.
If you hear a psychiatrist using the word "quantum" or if you hear him talking about "energy fields", that psychiatrist is a quack and you should run out of his office as fast as possible. Quantum mechanics has nothing to do with psychiatric treatment.
