a. Of or pertaining to quantum mechanics
Usage examples of "quantum-mechanical".
When the motion of a string is quantized, its possible vibrational states are represented by vectors in a Hilbert space, much as for any quantum-mechanical system.
A red dragonfly hovers above a backwater of the stream, its wings moving so fast that the eye sees not wings in movement but a probability distribution of where the wings might be, like electron orbitals: a quantum-mechanical effect that maybe explains why the insect can apparently teleport from one place to another, disappearing from one point and reappearing a couple of meters away, without seeming to pass through the space in between.
The Newtonian world view was as instinctively alien to Wan-To as quantum mechanics was to a human, because he himself was a quantum-mechanical phenomenon.
Well, recall from Chapter 8 that this constraint arises from counting the number of independent directions in which a string can vibrate, and requiring that this number be just right to ensure that quantum-mechanical probabilities have sensible values.
It would derive its power not only from its staggering number of processors but also from new advances in quantum computing--an emerging technology that allowed information to be stored as quantum-mechanical states rather than solely as binary data.
The numbers were provided on demand from a central source, accessible by WormCam, rumored to be a random number generator buried in a disused mine in Montana, based on uncrackable quantum-mechanical principles.
Colliding, fragmenting, and recombining at quantum-mechanical speeds, billions of different combinations came and went during every second of hundreds of millions of years.
