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…
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…
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…
Availing non-Markovian dynamics in effective negative temperature-based transient quantum Otto engines
Arghya Maity, Ahana Ghoshal
We demonstrate that the efficiency of effective negative temperature-based quantum Otto engines, already known to outperform their traditional counterparts operating with positive-…
