Experimentally probing the Quantum Physics in the Inverted Harmonic Oscillator
Si-Cong Ji, Philipp Schüttelkopf, Nataliia Bazhan +6
When a quantum system passes through an unstable fixed point the local dynamics reduces to the inverted harmonic oscillator (IHO). It exponentially amplifies along one quadrature w…

Quantum Transport Protected by Acceleration From Nonadiabaticity and Dissipation
Arnab Chakrabarti, Biswarup Ash, Igor Mazets +2
We put forth a hitherto unexplored control strategy that enables high-fidelity fast transport of an unstable quantum wavepacket even in the presence of bath-induced dissipation. Th…
