Optimal control of large quantum systems: assessing memory and runtime performance of GRAPE
Yunwei Lu, Sandeep Joshi, Vinh San Dinh +1
Gradient Ascent Pulse Engineering (GRAPE) is a popular technique in quantum optimal control, and can be combined with automatic differentiation (AD) to facilitate on-the-fly evalua…
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…
Mixed state geometric phase for neutrino oscillations
Sandeep Joshi
The geometric picture of neutrino oscillations offers a unique way to study the quantum mechanics of this phenomenon. In this picture, the propagation of a neutrino beam is describ…
Localization in one-dimensional relativistic quantum mechanics
Abhay Mehta, Sandeep Joshi, Sudhir R. Jain
We present the relativistic analogue of Anderson localization in one dimension. We use Dirac equation to calculate the transmission probability for a spin- particle in…
Neutrino spin-flavor oscillations in solar environment
Sandeep Joshi, Sudhir R. Jain
We study the phenomenon of neutrino spin-flavor oscillations due to solar magnetic fields. This allows us to examine how significantly the electron neutrinos produced in the solar…
