A Quaternary Legendre Pair of Length 64
Harshit Verma
We construct an explicit quaternary Legendre pair of length . To the best of our knowledge, this is the first reported construction at this length.
Optimizing resource allocation for accuracy in noisy variational quantum algorithms
Harshit Verma, Thomas Ayral, Alexia Auffèves +1
For quantum algorithms to achieve their full potential, we need methodologies to optimize them, such as reaching a given output accuracy with minimal resource costs. Here, we devel…
Measuring two temperatures using a single thermometer
Harshit Verma, Fabio Costa
We consider the question: Is it possible to measure two temperatures simultaneously using a single thermometer? Under common circumstances, where the thermometer can interact with…
Quantum information diode based on a magnonic crystal
Rohit K. Shukla, Levan Chotorlishvili, Vipin Vijayan +4
Exploiting the effect of nonreciprocal magnons in a system with no inversion symmetry, we propose a concept of a quantum information diode, {\it i.e.}, a device rectifying the amou…
Reassessing thermodynamic advantage from indefinite causal order
Matheus Capela, Harshit Verma, Fabio Costa +1
Indefinite causal order is a key feature involved in the study of quantum higher order transformations. Recently, intense research has been focused on possible advantages related t…
Operational models of temperature superpositions
Carolyn E. Wood, Harshit Verma, Fabio Costa +1
A quantum system and a thermal bath can reach thermal equilibrium through an interaction, whereupon the system acquires the same temperature as the bath. But how does a delocalised…
Constraining the number of fundamental quantum degrees of freedom using gravity
Harshit Verma, Magdalena Zych, Fabio Costa
We consider the effect of gravity on extended quantum systems (EQS) in the low energy regime. We model the gravitational effect due to a nearby source mass as a redshift in the int…
Quantum teleportation by utilizing helical spin chains for sharing entanglement
Harshit Verma, Levan Chotorlishvili, Jamal Berakdar +1
We develop a new protocol for sharing entanglement (one ebit) between two parties using the natural dynamics of helical multiferroic spin chains. We introduce a novel kicking schem…
Effect of environment on the interferometry of clocks
Harshit Verma, Magdalena Zych, Fabio Costa
Quantum interference of "clocks", namely of particles with time-evolving internal degrees of freedom (DOFs), is a promising avenue to test genuine general relativistic effects in q…
Schwinger's Model of Angular Momentum with GUP
Harshit Verma, Toshali Mitra, Bhabani Prasad Mandal
We study the generalized uncertainty principle (GUP) modified simple harmonic oscillator (SHO) in the operator formalism by considering the appropriate form of the creation and ann…
Qubit(s) transfer in helical spin chains
Harshit Verma, L. Chotorlishvili, J. Berakdar +1
Qubit(s) transfer through a helical chain is studied. We consider the transfer of a single state and Bell states across a multiferroic spin chain and the possibility of an electric…
