Lax pairs and -matrices for some two-dimensional isotropic oscillators

Govind S. Krishnaswami, Garima Rajpoot, Srividya N. Vaidya

This paper concerns Lax pairs for circularly symmetric harmonic, Fock-Darwin-type and quartic anharmonic oscillators in two dimensions. Although the 2d isotropic harmonic oscillato…

Quantum Simulation of Collective Neutrino Oscillations in Dense Neutrino Environment

Shvetaank Tripathi, Sandeep Joshi, Garima Rajpoot +1

Inside dense neutrino gases, such as neutron star mergers or core-collapse supernovae, collective neutrino effects cause the transformation of one neutrino flavour into another. Du…

Quantum circuits for simulating neutrino propagation in matter

Sandeep Joshi, Garima Rajpoot, Prashant Shukla

Quantum simulation of particle phenomena is a rapidly advancing field of research. With the widespread availability of quantum simulators, a given quantum system can be simulated i…

Controlling and engineering a quantum state in a multi-qubit system employing the quantum Zeno effect

Dhruva Naik, Garima Rajpoot, Sudhir Ranjan Jain

Controlling quantum jumps is crucial for reliable quantum computing. In this work, we demonstrate how the quantum Zeno effect can be applied to a two qubit system interacting with…

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…
