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…
The tunable 0-\texorpdfstring{}{Lg} qubit: Dynamics and Relaxation
Garima Rajpoot, Komal Kumari, Sandeep Joshi +1
We present a systematic treatment of a 0-\texorpdfstring{}{Lg} qubit in the presence of a time-dependent external flux. A gauge-invariant Lagrangian and the corresponding Hamilt…
Qubit control using quantum Zeno effect: Action principle approach
Komal Kumari, Garima Rajpoot, Sandeep Joshi +1
We employ the stochastic path-integral formalism and action principle for continuous quantum measurements - the Chantasri-Dressel-Jordan (CDJ) action formalism [1, 2] - to understa…
A Genus-two Surface Code
Komal Kumari, Garima Rajpoot, Sudhir Ranjan Jain
We construct a double-toric surface code by exploiting the planar tessellation using a rhombus-shaped tile. With n data qubits, we are able to encode at least n/3 logical qubits or…
