The quantum geometric limit

 


Abstract:

This talk derives quantum limits to the measurement of space-time geometry. Combining quantum limits to measurement accuracy of clocks and signals as in the global positioning system (GPS) with Einstein's theory of general relativity provides a quantum geometric limit to the number of elementary events -- ticks of clocks and clicks of detectors -- that can occur within a space-time volume.
