Local Universality and Structural Certificates for Minimal Fixed-Depth Two-Qutrit Gate Decomposition
Yurui Liu, Ruoting Dou, Peng Xu +4
We study a dimension-saturating fixed-core ansatz in which four copies of a fixed, non-tunable two-qutrit core are interleaved with five adjustable local layers from $…
Confidence uncertainty: position and momentum can be jointly determined with a guaranteed probability
Jia-Yi Lin, Xin-Yu Li, Wei Wang +1
Standard-deviation and entropic formulations of uncertainty principle capture the spread of the probability distribution but say little about the probability itself contained in a…
Wave-particle duality as an uncertainty relation for the average confidence width
Shengjun Wu
We introduce the average confidence width : the confidence width -- the smallest position interval carrying a fraction o…
A measure for genuine tripartite entanglement
Shengjun Wu, Kaichen Zhong, Jeffery Wu
We introduce a single real-valued functional , built from four three-qubit correlation expectation values, that turns the Greenberger--Horne--Zeilinger (GHZ…
Experimental asymmetric relativistic zero-knowledge proofs with unconditional security
Chen-Xun Weng, Ming-Yang Li, Nai-Rui Xu +6
Zero-knowledge proofs (ZKPs) are widely applied in digital economies, such as cryptocurrencies and smart contracts, for establishing trust and privacy between untrusted parties. Cl…
Weakly-Driven Quantum Walks for Memory-Constrained Pauli Channel Learning
Yuan-Zhuo Wang, Yi-Ran Xiao, Ming-Yang Li +2
Accurate characterization of quantum noise, exemplified by the Pauli channel, is a cornerstone for building fault-tolerant quantum computers. A recent protocol (PRX Quantum 6, 0203…
