Quasi-integrability and nonlinear resonances in cold atoms under modulation
Rahul Gupta, Manan Jain, Sudhir R. Jain
Quantum dynamics of a collection of atoms subjected to phase modulation has been carefully revisited. We present an exact analysis of the evolution of a two-level system (represent…

Quantum error correction beyond the toric code: dynamical systems meet encoding
Garima Rajpoot, Komal Kumari, Sudhir Ranjan Jain
We construct surface codes corresponding to genus greater than one in the context of quantum error correction. The architecture is inspired by the topology of invariant integral su…

Quantum Zeno effect: a qutrit controlled by a qubit
Komal Kumari, Garima Rajpoot, Sudhir Ranjan Jain
For a three-level system monitored by an ancilla, we show that quantum Zeno effect can be employed to control quantum jump for error correction. Further, we show that we can realiz…
