  A new class of atomic interferences using ultra-narrow optical transitions
are pushing quantum engineering control to a very high level of precision for a
next generation of sensors and quantum gate operations. In such context, we
propose a new quantum engineering approach to Ramsey-Bord\'e interferometry
introducing multiple composite laser pulses with tailored pulse duration, Rabi
field amplitude, frequency detuning and laser phase-step. We explore quantum
metrology with hyper-Ramsey and hyper-Hahn-Ramsey clocks below the $10^-18$
level of fractional accuracy by a fine tuning control of light excitation
parameters leading to spinor interferences protected against light-shift
coupled to laser-probe field variation. We review cooperative composite pulse
protocols to generate robust Ramsey-Bord\'e, Mach-Zehnder and double-loop
atomic sensors shielded against measurement distortion related to
Doppler-shifts and light-shifts coupled to pulse area errors. Fault-tolerant
auto-balanced hyper-interferometers are introduced eliminating several
technical laser pulse defects that can occur during the entire probing
interrogation protocol. Quantum sensors with composite pulses and ultra-cold
atomic sources should offer a new level of high accuracy in detection of
acceleration and rotation inducing phase-shifts, a strong improvement in tests
of fundamental physics with hyper-clocks while paving the way to a new
conception of atomic interferometers tracking space-time gravitational waves
with a very high sensitivity.
