A Minimum-Cardinality Genuinely Unextendible Product Basis in Three Qutrits
Fei Shi, Ge Bai, Xiande Zhang +2
It has remained an open question whether a genuinely unextendible product basis (GUPB) exists. We resolve this problem by constructing an explicit three-qutrit GUPB of cardinality…
Triage: An Adaptive Parallel Window Decoding Scheduler for Real-time Fault-Tolerant Quantum Computation
Jiahan Chen, Chenghong Zhu, Ge Bai +1
Fault-tolerant quantum computation (FTQC) critically depends on real-time classical decoding, which is rapidly emerging as a system bottleneck. As quantum systems scale, decoding l…
Observational entropy with general quantum priors
Ge Bai, Dominik Šafránek, Joseph Schindler +2
Observational entropy captures both the intrinsic uncertainty of a thermodynamic state and the lack of knowledge due to coarse-graining. We demonstrate two interpretations of obser…
Unextendible product bases from orthogonality graphs
Fei Shi, Ge Bai, Xiande Zhang +2
Unextendible product bases (UPBs) play a key role in the study of quantum entanglement and nonlocality. A famous open question is whether there exist genuinely unextendible product…
Quantum Similarity Testing with Convolutional Neural Networks
Ya-Dong Wu, Yan Zhu, Ge Bai +2
The task of testing whether two uncharacterized quantum devices behave in the same way is crucial for benchmarking near-term quantum computers and quantum simulators, but has so fa…
Flexible learning of quantum states with generative query neural networks
Yan Zhu, Ya-Dong Wu, Ge Bai +3
Deep neural networks are a powerful tool for the characterization of quantum states. Existing networks are typically trained with experimental data gathered from the specific quant…
Quantum autoencoders for communication-efficient quantum cloud computing
Yan Zhu, Ge Bai, Yuexuan Wang +2
In the model of quantum cloud computing, the server executes a computation on the quantum data provided by the client. In this scenario, it is important to reduce the amount of qua…
Quantum Causal Unravelling
Ge Bai, Ya-Dong Wu, Yan Zhu +2
Complex processes often arise from sequences of simpler interactions involving a few particles at a time. These interactions, however, may not be directly accessible to experiments…
Efficient verification of continuous-variable quantum states and devices without assuming identical and independent operations
Ya-Dong Wu, Ge Bai, Giulio Chiribella +1
Continuous-variable quantum information, encoded into infinite-dimensional quantum systems, is a promising platform for the realization of many quantum information protocols, inclu…
Efficient Algorithms for Causal Order Discovery in Quantum Networks
Ge Bai, Ya-Dong Wu, Yan Zhu +2
Given black-box access to the input and output systems, we develop the first efficient quantum causal order discovery algorithm with polynomial query complexity with respect to the…
Quantum Compression of Tensor Network States
Ge Bai, Yuxiang Yang, Giulio Chiribella
We design quantum compression algorithms for parametric families of tensor network states. We first establish an upper bound on the amount of memory needed to store an arbitrary st…
Test one to test many: a unified approach to quantum benchmarks
Ge Bai, Giulio Chiribella
Quantum benchmarks are routinely used to validate the experimental demonstration of quantum information protocols. Many relevant protocols, however, involve an infinite set of inpu…
Compression for quantum population coding
Yuxiang Yang, Ge Bai, Giulio Chiribella +1
We study the compression of n quantum systems, each prepared in the same state belonging to a given parametric family of quantum states. For a family of states with f independent p…
Quantum uncertainty relation using coherence
Xiao Yuan, Ge Bai, Tianyi Peng +1
Measurement outcomes of a quantum state can be genuinely random (unpredictable) according to the basic laws of quantum mechanics. The Heisenberg-Robertson uncertainty relation puts…
