Interactions Protect Periodically Driven Time Crystals Against Dephasing but Destabilise Multipolar-Driven Order
Karthikeya Machiraju, Kaustav Bhowmick
We show that stronger interactions protect periodically driven time-crystal order against dephasing but destabilise order under random multipolar drives, and that coordination matt…

Disentangling Expressibility, Symmetry Protection, and Hardware Noise in Variational Quantum Simulation of the Two-Flavor Schwinger Model
Karthikeya Machiraju, Krishna Sujith, Kaustav Bhowmick
Existing quantum simulations of the two-flavor Schwinger model have run at a single lattice size, and it is not known how far the variational approach can be pushed or which weakne…

A theoretical treatment of optical metasurfaces as an efficient basis for quantum correlations
Ramaseshan R, Prateek P. Kulkarni, Sharanya Madhusudhan +1
Entanglement is a cornerstone of quantum technology, playing a key role in quantum computing, cryptography, and information processing. Conventional methods for generating entangle…
