Quantum-to-classical transition and the emergence of trajectory level Darwinism with measurements distributed in time: a path integral approach
Harsh Arora, Bishal Kumar Das, Baladitya Suri +1
The paper develops a path‑integral framework that incorporates continuous measurements to explain how classical trajectories emerge from quantum dynamics, linking decoherence, quan…
Loschmidt echo and scrambling of systematic errors in tomography -- a quantum signature of chaos
Abinash Sahu, Naga Dileep Varikuti, Vaibhav Madhok
How does quantum chaos lead to rapid scrambling of information as well as systematic errors across a system when one introduces perturbations in the dynamics? What are its conseque…
Localizable Entanglement as an Order Parameter for Measurement-Induced Phase Transitions
Sourav Manna, Arul Lakshminarayan, Vaibhav Madhok
We identify localizable entanglement (LE) as an order parameter for measurement-induced phase transitions (MIPT). LE exhibits universal finite-size scaling with critical exponents…
Absence of quantum Darwinism as a resource in secure quantum communication and computation
Bishal Kumar Das, Sourav Manna, Vaibhav Madhok
The emergence of classical world from underlying quantum mechanics is characterized by not only vanishing quantum correlations but also an unfolding of objectivity also known as qu…
Entangling power, gate typicality, and measurement-induced phase transitions
Sourav Manna, Vaibhav Madhok, Arul Lakshminarayan
When subject to a non-local unitary evolution, qubits in a quantum circuit become increasingly entangled. Conversely, measurements applied to individual qubits lead to their disent…
On Simultaneous Information and Energy Transmission through Quantum Channels
Bishal Kumar Das, Lav R. Varshney, Vaibhav Madhok
The optimal rate at which information can be sent through a quantum channel when the transmitted signal must simultaneously carry some minimum amount of energy is characterized. To…
