Optimal query complexity for fractional quantum evolution
Anthony Yuezhang Liu, Adam Wesołowski, Jayne Thompson +2
Given oracle access to an unknown unitary , the fractional query problem asks how many queries are required to implement a noninteger power , , when…
Virtual quantum resource distillation: General framework and applications
Ryuji Takagi, Xiao Yuan, Bartosz Regula +1
We develop the general framework of virtual resource distillation -- an alternative distillation strategy proposed in [Phys. Rev. Lett. 132, 050203 (2024)], which extends conventio…
Causal Asymmetry of Classical and Quantum Autonomous Agents
Spiros Kechrimparis, Mile Gu, Hyukjoon Kwon
Why is it that a ticking clock typically becomes less accurate when subject to outside noise but rarely the reverse? Here, we formalize this phenomenon by introducing process causa…
Quantum sensing of phase-covariant optical channels
Ranjith Nair, Mile Gu
We obtain universal (i.e., probe and measurement-independent) performance bounds on ancilla-assisted quantum sensing of multiple parameters of phase-covariant optical channels unde…
Causal classification of spatiotemporal quantum correlations
Minjeong Song, Varun Narasimhachar, Bartosz Regula +2
From correlations in measurement outcomes alone, can two otherwise isolated parties establish whether such correlations are atemporal? That is, can they rule out that they have bee…
Quantum Uncertainty Principles for Measurements with Interventions
Yunlong Xiao, Yuxiang Yang, Ximing Wang +2
Heisenberg's uncertainty principle implies fundamental constraints on what properties of a quantum system can we simultaneously learn. However, it typically assumes that we probe t…
