Towards fault-tolerance with universal phase-error-transparent gates for high-spin cat codes
Kelvin Onggadinata, Si Yan Koh, Arghya Maity +5
High-dimensional nuclear spins offer a hardware-efficient route to quantum error correction (QEC), with the spin cat code providing intrinsic robustness against phase errors -- the…
Exact Tradeoff Between Quantum Error Correction and Quantum Darwinism: An Information-Theoretic No-Go Theorem
Arghya Maity, Kelvin Onggadinata, Teck Seng Koh
Quantum error correction (QEC) and Quantum Darwinism describe opposing consequences of system-environment interactions: QEC seeks to preserve logical quantum information, whereas Q…
Non-Markovian and Thermodynamic Signatures in the Classicality Assessment via Kolmogorov Consistency
Arghya Maity, Ahana Ghoshal, Kelvin Onggadinata +1
The Kolmogorov consistency condition (KCC) defines the statistical boundary between classical and quantum dynamics. Its violation signifies the breakdown of a classical Markov desc…
Quantum Heat Transformers
Arghya Maity, Paranjoy Chaki, Ahana Ghoshal +1
We propose a quantum heat transformer (QHT), a quantum thermodynamic device that modulates temperature gradients between two thermal junctions in quantum systems. Functionally, the…
Violation of the thermodynamic uncertainty relation in quantum collisional models
Arghya Maity, Ahana Ghoshal
The thermodynamic uncertainty relation (TUR) is a fundamental principle in non-equilibrium thermodynamics that relates entropy production to fluctuations in a system, establishing…
