Enhancing the phase sensitivity of a Mach-Zehnder interferometer beyond the Heisenberg limit through dynamic squeezing
Lakshya Bhardwaj, Ankit Tiwari, Mohan Sarovar +1
We propose a method to enhance the phase sensitivity of a Mach-Zehnder interferometer, independent of its input states. This is achieved by applying squeezing sequences to one arm…

Amplification of bosonic interactions through squeezing in the presence of decoherence
Ankit Tiwari, Cecilia Cormick, Christian Arenz
We consider the amplification of bosonic interactions through parametric control that implements squeezing along orthogonal quadratures. We show that bosonic interactions described…

Loss tolerant cross-Kerr enhancement via modulated squeezing
Ankit Tiwari, Daniel Burgarth, Linran Fan +2
We develop squeezing protocols to enhance cross-Kerr interactions. We show that through alternating between squeezing along different quadratures of a single photonic mode, the cro…
