Universal Sampling Lower Bounds for Quantum Error Mitigation
Ryuji Takagi, Hiroyasu Tajima, Mile Gu
Numerous quantum error-mitigation protocols have been proposed, motivated by the critical need to suppress noise effects on intermediate-scale quantum devices. Yet, their general p…

Universal trade-off structure between symmetry, irreversibility, and quantum coherence in quantum processes
Hiroyasu Tajima, Ryuji Takagi, Yui Kuramochi
Symmetry, irreversibility, and quantum coherence are foundational concepts in physics. Here, we present a universal tradeoff relation between these three concepts. This particularl…
