What Penrose suggests is that the human brain itself is a kind of quantum device.

Now a quantum device such as the drive is very specialized and needs to be kept as isolated as possible.

I'm torn between this and the macro-scale quantum device.

(Exactly what unitaries can be applied depend on the physics of the quantum device.)

She stared at the fist-sized quantum device with loathing.

In theory, this could run about 30% faster and use less power, as well as permit a direct interface with quantum computational devices.

In short, the classical mechanical resonance was creating a feature that could be detected with a quantum device.

Dr. Bennett predicted that quantum cryptographic devices might find a niche in corporate suites.

Such quantum devices represent perhaps the most exciting frontier in semiconductor research today, promising smaller and faster electronic circuitry.

But, he said, quantum devices will be used for communications and electronic instruments.
