Time-ordered free energy in correlated quantum systems: An agentic approach
Ruo Cheng Huang, Isha Singh Le Xue, Yuxuan Qu +3
How much work can an agent extract from a temporal sequence of quantum states when it can only operate online under causal constraints---deciding which energy extraction method to…
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…
Optimized circuits for windowed modular arithmetic with applications to quantum attacks against RSA
Alessandro Luongo, Varun Narasimhachar, Adithya Sireesh
Windowed arithmetic [Gidney, 2019] is a technique for reducing the cost of quantum arithmetic circuits with space--time tradeoffs using memory queries to precomputed tables. It can…
Measurement-based uncomputation of quantum circuits for modular arithmetic
Alessandro Luongo, Antonio Michele Miti, Varun Narasimhachar +1
Measurement-based uncomputation (MBU) is a technique used to perform probabilistic uncomputation of quantum circuits. We formalize this technique for the case of single-qubit regis…
Amplification, Mitigation and Energy Storage via Constrained Thermalization
Harshank Shrotriya, Midhun Krishna, Leong-Chuan Kwek +2
Amplification (mitigation) is the increase (decrease) in the change of thermodynamic quantities when an initial thermal state is thermalized to a different temperature in the prese…
