good quantum control: high fidelity, fast operation
Quantum Effect consideration scenarios: [ultra-cold, ultra-fast, ultra-small three or [one] of the extremely accurate time measurement]
spatial scale small to some extent; low temperature to a certain temperature; to observe the system time scale ultra-small when
Heisenberg principle:
[Ultracold] After ultra-cold temperatures to a certain system into a low energy quantum parts for every one part.
[Ultra-small energy gap]> energy field
[] ultra-fast frequency as high as possible, (soldiers cross the bridge)
Controlling ion
in the case without reciprocal AB, can not accurately measure the two or more physical quantities, A is the measurement of B can not be measured, which is the result of lack of mutual Heisenberg Uncertainty Principle.
