BARC codes: general polynomial framework for coherent-state superposition codes
Praneel Gore, Davit Aghamalyan, Varun Narasimhachar +1
We introduce an algebraic framework for constructing a new class of quantum error-correcting codes, bosonic algebraically-restricted constellation (BARC) codes. The code states are…
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…
