Quantum-enhanced sensing in a driven-dissipative system via chiral waveguide
Yan Xi Foo, Saubhik Sarkar, Leong Chuan Kwek +2
Quantum sensors can achieve precision unattainable by classical sensors. However, dissipation coming from interaction with the environment can greatly degrade the performance of qu…
Transient entanglement generation in driven chiral networks beyond the secular approximation
Yan Xi Foo, Kian Hwee Lim, Jia-Bin You +2
We study transient entanglement generation between two quantum nodes coupled through a chiral one-dimensional channel. In an emitter-only Born-Markov description, we show that cont…
Approximate virtual quantum broadcasting
Matthew Simon Tan, Davit Aghamalyan, Varun Narasimhachar
The no-broadcasting theorem, a fundamental limitation on the communication of quantum information, holds that a physical process cannot broadcast copies of an unknown quantum state…
The Dirac--Bergmann approach to optimal control theory
Davit Aghamalyan, Aleek Maity, Varun Narasimhachar +1
We present a novel framework for optimal control in both classical and quantum systems. Our approach leverages the Dirac--Bergmann algorithm: a systematic method for formulating an…
Data re-uploading in Quantum Machine Learning for time series: application to traffic forecasting
Nikolaos Schetakis, Paolo Bonfini, Negin Alisoltani +6
Accurate traffic forecasting plays a crucial role in modern Intelligent Transportation Systems (ITS), as it enables real-time traffic flow management, reduces congestion, and impro…
Generation and optimization of entanglement between atoms chirally coupled to spin cavities
Jia-Bin You, Jian Feng Kong, Davit Aghamalyan +5
We explore the generation and optimization of entanglement between atoms chirally coupled to finite 1D spin chains, functioning as {\it spin cavities}. By diagonalizing the spin ca…
