I investigate how quantum systems behave under measurements and how entanglement structures emerge and evolve in complex quantum circuits.\nCurrent Projects # Below are my main research projects, each exploring different aspects of quantum information and many-body physics:\nMeasurement-Induced Phase Transition (MIPT) # Quantum measurements compete with unitary evolution to shape the entanglement structure of quantum many-body systems, giving rise to measurement-induced phase transitions (MIPTs). In our recent work, we showed that in brickwall circuits, the critical parameter of the phase transition can be tuned by modifying the properties of the two-qubit gates. For more details, see the paper, which is also listed on the Publications page.\nMy ongoing research explores how local entanglement structures evolve under non-unitary dynamics, particularly in circuits involving unitary operations interspersed with measurements.\nResearch Output # For a complete list of my publications, conference presentations, and preprints, please visit the Publications page.\nCollaborations # Dr. Vaibhav Madhok, Department of Physics, IIT Madras Prof. Arul Lakshminarayan, Department of Physics, IIT Madras For more information about specific projects or potential collaborations, please contact me.\n","date":"1 January 2024","externalUrl":null,"permalink":"/research/","section":"Research Overview","summary":"\u003c!-- # Research Overview --\u003e\n\u003cp\u003eMy research centers on \u003cstrong\u003equantum information theory\u003c/strong\u003e, \u003cstrong\u003equantum simulation\u003c/strong\u003e, \u003cstrong\u003emany-body entanglement\u003c/strong\u003e, \u003cstrong\u003equantum cryptography\u003c/strong\u003e, \u003cstrong\u003emeasurement-induced phase transitions\u003c/strong\u003e, and \u003cstrong\u003equantum chaos\u003c/strong\u003e.
