Quantification of Entanglement and Coherence with Purity Detection
Ting Zhang, Graeme Smith, John A. Smolin +7
Entanglement and coherence are fundamental properties of quantum systems, promising to power near future quantum technologies, such as quantum computation, quantum communication an…
Optimal one-shot entanglement sharing
Vikesh Siddhu, John Smolin
Sharing entanglement across quantum interconnects is fundamental for quantum information processing. We discuss a practical setting where this interconnect, modeled by a quantum ch…
The platypus of the quantum channel zoo
Felix Leditzky, Debbie Leung, Vikesh Siddhu +2
Understanding quantum channels and the strange behavior of their capacities is a key objective of quantum information theory. Here we study a remarkably simple, low-dimensional, si…
Generic nonadditivity of quantum capacity in simple channels
Felix Leditzky, Debbie Leung, Vikesh Siddhu +2
Determining capacities of quantum channels is a fundamental question in quantum information theory. Despite having rigorous coding theorems quantifying the flow of information acro…
Active Learning of Quantum System Hamiltonians yields Query Advantage
Arkopal Dutt, Edwin Pednault, Chai Wah Wu +4
Hamiltonian learning is an important procedure in quantum system identification, calibration, and successful operation of quantum computers. Through queries to the quantum system,…
Hardware-efficient random circuits to classify noise in a multi-qubit system
Jin-Sung Kim, Lev S. Bishop, Antonio D. Corcoles +3
In this work we extend a multi-qubit benchmarking technique known as the Binned Output Generation (BOG) in order to discriminate between coherent and incoherent noise sources in th…
