If you encounter a clinic offering a “Quantum Resonance scan,” your best medical decision is to walk out. Save your money for a test that actually measures reality—and leave quantum mechanics to the physicists.

Quantum effects in biology (e.g., photosynthesis, avian magnetoreception) occur at molecular scales and require near-absolute-zero temperatures and shielded environments. A $2 USB chip cannot detect quantum signals from a liver through clothing and air.

Teardowns of the QRMA 6.3 by electronics engineers (available on YouTube and EEVblog) reveal the probe contains a simple temperature sensor (an NTC thermistor) and a noise generator. The device measures your skin temperature and then—using a random number generator—selects a pre-written report from a database. The “magnetic field” it detects is the ambient 50/60Hz hum from power lines.
